Do Dogs Have Belly Buttons?

by Kate Barrington

Published: October 24th, 2017

Is it an innie or an outie? No, we’re not talking about you – we’re talking about your dog! Have you ever noticed if your dog has a belly button?

The belly button is just another part of the human anatomy that most people are familiar with. When you are born as an infant, the doctor clamps and cuts the umbilical cord – what remains attached to the body eventually shrivels and falls off, leaving behind the belly button. Dogs are mammals, as are humans, so it only makes sense that they have belly buttons – or do they?

Does Your Dog Have a Belly Button?

All mammals give birth to live young. The babies develop inside the mother’s womb where they are connected to her life’s blood via the umbilical cord. Nutrients and oxygen are delivered to the babies through the umbilical cord and it also carries waste products away.

When babies are born, they are still attached to the umbilical cord so it must be severed to allow the baby to live on its own. After birth, the mother typically bites off the umbilical cord which leaves a scar behind. The scar left behind is the equivalent of the belly button in humans, though it may not look quite the same. All mammals, including dogs, have belly buttons with the exception of marsupials.

What Does a Dog’s Belly Button Look Like?

A dog’s belly button is more of a scar that is left behind when the umbilical cord is severed. Because your dog’s belly is covered in hair, you probably won’t even be able to see the belly button unless you look for it. Another reason you probably won’t notice the belly button is because it will be tiny – puppies are smaller than human babies, so the umbilical cord is narrower. Whereas the human belly button forms a round hole, a dog’s belly button forms a slit. If you want to locate it, look for it on the underside of the dog’s belly at the point where the coat comes together at the base of the dog’s ribs.

If your dog’s belly button starts to protrude, it could be cause for concern – a swollen belly button in dogs is often the result of an umbilical hernia and, left untreated, it can become fatal. Any swelling around your dog’s belly button is cause for concern so you should contact your veterinarian.

A hernia develops when something that is meant to stay protected inside the body bulges out. If the hernia remains very small and uncomplicated it may resolve itself in time but large, complicated umbilical hernias require veterinary treatment. Some breeds that seem predisposed to umbilical hernias include Beagles, Basenjis, Pekingese, and Airedale Terriers.

The more you know about your dog’s anatomy, the better you will be able to identify problems when the occur. In a normal, healthy dog you probably won’t be able to see or feel the belly button unless it becomes herniated. At that point, you should seek immediate veterinary care for your dog because it could become dangerous without treatment.

Why Do Some Dogs Have Bad Body Odor?

Dogs are cute, no doubt about that, but most of them are not winning awards for their lovely BO – in fact, if we’re being honest, most pooches are a bit stinky. Of course, if you make sure to keep them clean with regular baths, grooming, and teeth brushing, you can eliminate or at least significantly reduce any unpleasant smell. But sometimes, even if you are very attentive about your dog’s hygiene, they can still smell a bit funky. Why does this happen? And what should you do in that case? Lastly, is there a way to prevent unpleasant body odors in your dog? Let’s try and answer all these stinky questions.Why Does My Dog Smell Bad?Are you catching a whiff of something foul whenever your dog enters the room? Are you struggling to keep them clean and smelling fresh? There could be a number of reasons why your pupper is stinky, and it is important to go over everything in order to properly address this issue. Firstly, you want to consider their hygiene. Lack of regular grooming and bathing can lead to a buildup of dirt, oils, and bacteria on a dog's skin and coat, resulting in a bad odor. Make sure you are giving your dog a regular wash or a bath, and that you are using  special shampoos that are safe for pets and smell nice.

Do Dogs Have a Concept of Time?

Can your dog tell the time? When you’re at work all day, it’s not like your dog can watch the clock until you get home. They say that time flies when you’re having fun, but even when time seems to be passing more quickly than usual, you have an awareness of its passing. As humans, many of us live in a 9-to-5 world where 8 hours of each day belongs to someone else and that time often seems to creep by slowly while time off passes before you know it. Dogs have very few responsibilities and demands on their time, so it may lead you to wonder whether they understand the concept of time at all. Many animal experts say that dogs live in the moment – they are not haunted by past events or anxious about the future like humans are. But are they actually aware of the passing of time or do they have a concept of time at all? Keep reading to find out. Related: Is Your Anxiety Contagious to Your Dog? How Do Dogs Understand Time? There are days when you don’t even have to say a word to your dog – he automatically knows when it is time to head to the dog park. And you’ve probably noticed that your dog is waiting by the door when you come home from work at the usual time. Dogs often seem to have a strangely accurate concept of time, but it begs the question – do they actually know what time it is, or is something else going on? It is difficult to explain a dog’s perception of time, because the only point of comparison is a human’s concept of time. Humans have the ability to quantify time and to break it down into artificial measures such as seconds, minutes, and hours. This is possible because humans have episodic memories that enable us to recall past events and to anticipate events in the future. Dogs don’t perceive time in this same way, but that doesn’t mean that live stuck in the moment. Though your dog may not be able to recall the details of an entire day six months ago, they can distinguish how much time has passed since a certain event. For example, they may know that it has been six hours since they went outside. Related: 5 Stress-Free Ways To Deal With Dog Separation Anxiety How Dogs Understand the Passing of Time Scientists suggest that, like humans, dogs have an internal clock called a circadian rhythm which operates on a roughly 24-hour cycle. This cycle responds to cues like daylight and darkness and can be used to keep track of time by associating a particular event with a time of day. Some even say that dogs may respond to changing scents throughout the day and, in this way, can actually smell time. Another interesting concept to address is how a dog’s concept of time changes when left alone versus time spent with its owner. Studies have shown that dogs display a greater degree of affection toward their owners if they have been separated for a significant amount of time. As the duration of the separation increases, so does the dog’s excitement. This highlights the fact that dogs are able to recognize and respond to different spans of time, a concept that comes into play for dogs with separation anxiety. The difference between one hour of separation and five hours could be the different between mild agitation and a full-blown anxiety attack. Time is a strange thing, whether you’re a human or a dog. Though your dog may not experience time in quite the same way that you do, he does have his own concept of it and learning to work around your dog’s perception of time could help you better understand him.

Watch As Adorable Shelter Dogs Pick Their Own Christmas Toys

The holiday season is associated with traditions and festivities as we gather with family, put up festive decorations, and exchange holiday gifts. For pet parents, these traditions often carry over to spoiling our furry companions. But what about the thousands of pets sitting in shelters and rescues around the world, waiting for their forever home?One rescue based in Ireland has embraced a heartwarming tradition since 2017. Each year, Dogs Trust Ireland collects donations from the public. Hundreds of donated toys are placed in a room, and the pets are brought in one at a time to select their perfect holiday gift. They record the selection process, sharing the adorable footage on their YouTube channel for animal lovers worldwide to enjoy. “The reason we love making the video so much is that it’s so special to witness each dog’s individual reaction. Some burst in the door and scatter toys everywhere in an excited frenzy, and when they choose ‘the’ toy, they do excited zoomies,” explained Corina Fitzsimons, Public Relations and Communications Manager. “For dog lovers, it doesn’t get much better than seeing dogs doing Zoomies! Others prefer people and, after a sniff, will come over for cuddles. Then there are those who test every toy three or four times before picking, and many of the Collies who find a plain ball, throw it at our feet, and look at us as if to say, ‘Please throw human,’ which we are happy to oblige with.” This year, a total of 54 dogs were recorded as they carefully made their selection. While some dogs quickly found that perfect holiday toy, others took as long as 20 minutes to settle on a favorite. The organization promises that every one of the 264 dogs in their care will receive at least one toy during the holiday season, thanks to the generous donations they received.

What Should I Do If My Dog is Afraid of Nail Trims?

The dreaded nail clippers – a source of stress and occasional doggy drama in our home as well as for many dog parents. You see, our youngest pup, Lucifer, and I have been on quite the journey to conquer his fear of nail trimming. If you’ve ever found yourself in a similar situation, you know the struggle all too well!But fear not, because in this article, I’m sharing our personal tale of progress and a toolkit of tips we’ve picked up along the way to help overcome your dog’s fear of nail clipping.So, let’s swap nail-trimming anxiety for confidence and cooperation, one paw at a time.Why Does My Dog Hate Nail Trims?The first step to overcoming a fear of nail trims is understanding why the sight of nail clippers is a source of anxiety for your dog. After all, the clippers themselves aren’t frightening or intimidating.For many dogs, the fear of having their nails cut is rooted in a desire to protect their paws. This is a survival instinct, as they need their paws to survive in the wild, both to escape predators and be able to catch food. They haven’t been taught that the process of having their nails cut or their paws handled isn’t going to cause harm.If your dog was previously okay with having their nails trimmed and suddenly changes their mind and lashes out when you try, this is a sign of trouble. Have you recently cut your dog`s nail and accidentally nicked the quick of the nail? If so, your dog may associate the experience with the pain and discomfort they felt at that moment.This could also indicate that your dog feels pain in their leg or paw. Watch for other signs of distress or discomfort, like lameness, limping, or excessively licking the area. If you suspect your dog is in pain or if your dog has shown a behavior change that you can’t otherwise explain, contact your veterinarian. They can run the tests necessary to help diagnose the problem and recommend ways to provide effective pain relief.For us, with Lucifer, we are overcoming a reaction due to previous pain. He suffered injuries to his front paws before he was rescued and adopted out to us as a puppy. While we have worked with specialists to help him heal and move on from these injuries, he is still more protective of his paws and dislikes having them handled. What Happens if You Wait Too Long to Cut Dog Nails?Keeping your dog’s nails trimmed and cared for is an integral part of grooming. How often you need to trim their nails will vary, depending on their breed, age, and lifestyle. Some dogs will naturally wear down their nails from walking and running on rough surfaces, as they would in the wild, while others don’t engage in these activities frequently enough to keep up with nail growth.When a dog’s nails become overgrown, they interfere with their ability to stand and walk properly, reducing traction and potentially causing injuries in their feet and tendons. This is because the nails contact the floor before their paw pads. Over time, this can also lead to long-term injuries, deformities in the paw or leg, or arthritis. This can also cause older dogs to slip and fall due to losing traction and unsteadiness on their feet.

“One-of-a-Kind” Cat With Two Noses Searches for Her Forever Home

As rescue cat parents and rescue advocates, we know firsthand that every cat has a unique story to tell. But some cats truly stand out and make their mark on the world. Nanny McPhee, a rescue cat who recently came into the care of the Cats Protection Warrington Adoption Centre. It’s not the way this sweet girl came into the shelter or her life before that has everyone talking… It’s a VERY unique physical feature – her nose, or “noses,” in her case! The sweet kitty lived in a loving home for the first four years of her life. Unfortunately, her previous owner had to make the difficult decision to contact a rescue due to health and financial reasons. When Nanny McPhee first arrived at the rescue, volunteers and rescue workers noticed a few things about the tuxedo kitty. First, she was a very gentle lady with a love for attention.“She has proven to be a gentle lady who adores a fuss and a cuddle, and we are hopeful her new-found fame will mean she will have no shortage of potential adopters,” shared shelter manager Lindsay Kerr. “She really does deserve a home where she can settle down and become the center of a loving family.” Second, they noticed she had a surprisingly large nose. It was this unique feature that led to her being named after the popular children’s character. But that signature sniffer was hiding an even bigger secret. A check-up with a local veterinarian revealed that the cat had not one but TWO noses, creating the appearance of one large snout. When asked about the discovery, senior field veterinary officer Fiona Brockbank explained that it was the first time they had seen this but that the cat’s unique appearance resulted from a congenital malformation. Other more common examples of this include cleft palates or cleft lips. These conditions can be inherited or caused by an incident during development in utero.

What Age Should You Start Clicker Training?

Clicker training is a popular form of positive reinforcement dog training that uses a small handheld device called a clicker to mark and reinforce desired behaviors. The clicker makes a distinct and consistent sound that signals to the dog that they have performed the desired behavior, followed by a reward such as a treat or praise. The idea is to associate the sound of the clicker with the reward, making it a powerful tool for communication between the owner and the dog.Now, if you want to try clicker training with your dog, you could be wondering at what age should you start. Very early on? Or as your puppy grows a bit older? Let’s find out.What Age Should You Start Clicker Training?Clicker training is versatile and can be used for teaching  basic commands, tricks, and even addressing behavioral issues. It is a humane and positive approach to training that fosters a strong bond between the owner and the dog. Clicker training can be started with dogs at a relatively young age, typically when they are around 8 weeks old. Puppies are capable of learning basic commands and behaviors from a young age, and clicker training can be a positive and effective method for teaching them.However, it's important to keep in mind that very young puppies have shorter attention spans, so training sessions should be kept short and fun. Focus on simple commands and behaviors, and use positive reinforcement, such as treats or praise, in conjunction with the clicker.Consistency and patience are key when training puppies, and it's important to make the training sessions enjoyable for them. Stay consistent and maintain your composure and command. Even if the early training sessions last just a few minutes, keep it up. Of course, if you're unsure about how to start clicker training or have concerns about your puppy's readiness, consulting with a professional dog trainer or attending puppy training classes can be helpful. Always use positive reinforcement methods to create a positive and trusting relationship between you and your dog.Remember that clicker training requires patience and hard work to be successful. The idea is to associate the sound of the clicker with positive reinforcement, making it a powerful tool for communication between the owner and the dog.4 Things to Know About Clicker TrainingTo ensure your training sessions with a clicker are successful no matter when you start implementing them in your pet’s routine, you need to know the basics. These tips will help you optimize your process for maximum efficiency:Timing is KeyClicker training relies on precise timing. The click should occur at the exact moment your dog exhibits the desired behavior. This helps your dog make the connection between the behavior and the reward.Positive Reinforcement

A New Survey Shows Both Pets and Owners Feel Separation Anxiety

When you really love spending time with your pet, and vice versa, it is only natural that you feel sad when you are apart. For pets, this is often manifested as the dreaded  separation anxiety, which can cause a lot of issues both for them and their owners alike. While you know you are coming back from work – unlike your pooch – so you won’t feel as stressed about the time you spend away from your pet, that doesn’t mean that it won’t affect your mental health. The latest  survey from PetMed Express only proves that separation has an effect both on dogs and their pawrents.The results of this survey were recently released after being conducted by OnePoll, and they show us that pet parents – unsurprisingly – while out away for work or chores, will deeply miss their four-legged friends back at home. And, interestingly, the poll shows that the strain only got worse after the owners had to return to their offices after the Covid pandemic and the time they spent in their homes. "This research confirms what we already know: People love their pets and prioritize being with them," said Matt Hulett, President and CEO of PetMeds. "What's eye-opening is how many pet parents feel their own sense of separation anxiety and loneliness when they're away from their pets – a concept that underscores the pivotal role our pets play in our lives."The results indicate that 4 in 10 pet parents said that they would rather accept a lower salary and work from home, just so they could be closer to their furry friends. It is a sad truth and an everyday occurrence that owners have to endure the commute and long work hours and yearn for the company of their pets all the while. PetMeds claims that pet parents begin to miss their pets just 37 minutes after being apart, on average. Furthermore, the results show that on average they find themselves thinking about their pets about 13 times per day. Here are some other stats included:44% expressed worry about their pets experiencing separation anxiety52% have felt an increase in their own separation anxiety in the past two years42% said they have observed a change in their pet's mental health and behavior in the past two years48% said their pets follow them to the door and look sad when they leave63% would like more support and guidance in understanding their pet's health and behavior70% would try pet telehealth servicesWhat about you? How do you cope with being separated from your cherished four-legged friend?

Dog Who Spent 900 Days in a Shelter Returned 1 Day After Being Adopted

The staff at the Valley Animal Center in Fresno, California was joyous when a Labrador retriever pit bull mix named Sora was finally adopted. Sora, who was the shelter’s longest resident, has waited 900 days to be adopted into a loving, furever home.Sadly, less than 24 hours after the adoption, the poor pooch was returned to the shelter. The Valley Animal Center in Fresno, the largest no-kill shelter in California’s Central Valley, welcomed Sora nearly 4 years ago after the pup’s previous owners surrendered the pet. Since then, Sora hasn’t garnered much attention from prospective adopters, which is shocking to shelter staff who know the pooch well. “Sora is a high-energy dog who loves to play and gets super excited anytime she gets to go on walks,” said Sim Kaur from Valley Animal Center to Newsweek. According to Kaur, Sora loves to walk and hike and will make an amazing travel companion to an outdoorsy person. The sweet pooch also loves playing with tennis balls and is always in the mood for a game of fetch. Sora has tested well with children over the age of five and is affectionate and lovable with adults.Despite being overlooked for so many years, this cute pup recently caught the attention of a potential adopter. After a few meetings, the person decided to adopt Sora, giving this pooch the happy ending she deserved.Then, the worst possible thing happened! Just 24 hours later, the new owner called the shelter to say they would be returning the pup. Sora arrived at the shelter heartbroken and looked particularly sad to be back in the same kennel she called home for so many years.This turn of events shocked Kaur, who believed Sora’s adopters should have given her more time to decompress and settle in her new home before deciding to return the pet to the shelter.“Being in a shelter for many years affects the mental health of our adoptables and it is no different for Sora,” she added. “Sora did not get enough time to decompress in her new home and was introduced to new family members too quickly.”Sora’s sad story was posted on TikTok and has received more than 1.6 million views, leaving doggy lovers around the world in tears. Sharing the video of Sora with another pooch, Eros, who was also returned quickly after adoption, the shelter wrote: “Their tails wagging with hope as they were welcomed into their new home. However, after a short period of time, these shelter dogs found themselves back in their kennels. They are still hopeful that somewhere out there is their furever home where they will be cherished as they deserve.”One day is not enough time for a shelter dog to adjust to its new home. Especially, if the dog in question has spent more than 900 days stuck inside a shelter. Unfortunately, staff at animal shelters see this happen often. Some people who adopt shelter dogs simply don’t give them the time they need to adjust to a new home, and all the unfamiliar sights, smells, and people. It comes as no surprise, to most people, that any dog that has spent any time in a shelter, much less 900 days, will need some time to adapt to its new life and recover from the stress they have experienced. Hopefully, the next person who adopts Sora will understand her and give her the time she needs to adjust to her new home. This adorable pooch is still looking for her furever home. If you think Sora will fit right into your family, submit an adoption application here. Join the PetGuide community.

Latest Studies Find That Aging in Dogs Can Mirror Aging in Humans

In the United States alone, pet owners spend around $1,500 a year on  veterinary care. To be precise, people tend to spend more on dogs than on any other pets – up to 41% of Americans spend $2,000 per year caring about their cherished canine friends. Of course, this is all in the hopes that their pet reaches their senior age with minimal issues and that they get to spend as many years enjoying their company. While providing veterinary care is an important factor that contributes to a pet’s longevity, it’s not always easy to determine when a certain procedure or treatment will help prolong your pet’s life and not their suffering. By comparing the concept they labeled “frailty” in humans and in dogs, a team of researchers hopes that they can help owners make better decisions about their pet’s care.Scientists behind the “ Dog Aging Project” are studying how they could improve your dog’s quality of life for many years to come. The team from the University of Washington is conducting extensive research, based on dogs of all ages, in their attempts to determine how their quality of life is impacted as they age. Dr. Anya Gambino, one of the chief veterinarians working on the project, says: “There's a quantity of life. It's amazing to have a long life, but you always want to have quality of life." The team’s UW Biologist and the Co-Director of the Project, Daniel Promislow, quickly drew a parallel with humans. "Dogs get the same kinds of diseases that humans get. They also show the same kinds of frailty that we see in humans," he said.The so-called “frailty” of dogs, which is the object of the study, is already studied in humans. Dr. Promislow firmly believes that through this study, researchers can gain a much better understanding of life expectancies in dogs and potential disease risks as well. "We hope we'll be able to figure out the relationship between frailty and the disease," Promislow says. But what exactly is this “frailty”? Researchers describe it as "a complex syndrome associated with aging. Because it considers physical, mental and emotional changes associated with aging, it is a better indicator of the body’s condition and overall health than age alone.""If we can do that, we can help vets treat dogs earlier before those diseases are apparent and can also help dogs enjoy their later years to the best degree possible," said Promislow.The study is on a very grand scale and already enrolls over 46,000 dogs across the United States. What is best, researchers believe that humans can also benefit from this extensive study. "The other thing about aging in dogs is that aging in dogs looks a lot like aging in people," said Promislow. "What we learn about aging in dogs is going to help us learn about aging in people, as well."Hopefully, this would mean that many more dogs would get a chance to enjoy their golden years, right by their owner's side. "They provide us with so much unconditional love, joy, and humor," said Dr. Gambino. "We can do something for them that gives them the best chance for living a very happy life with us."

How Much Playtime Does My Cat Need?

Sure, cats tend to spend a lot of their day seemingly lazing about, basking in the sun, meticulously cleaning themselves, and snoozing away. However, that doesn’t mean that cats are not active animals that need daily exercise – they have an instinct to hunt, explore, and engage in different activities that stimulate their minds and bodies. Without adequate mental and physical stimulation, cats can become bored, stressed, and even develop behavioral issues. This is why playtime is not “just” a matter of playing for felines. It meets their most basic needs and it's an essential component of their overall well-being.What Are the Benefits of Playtime for Cats?Engaging your cat in interactive play stimulates their cognitive abilities, keeping their minds sharp and active. Activities like chasing toys, solving puzzles, or hunting for treats mimic their natural hunting instincts, providing mental enrichment. Enrichment is crucial to prevent destructive behaviors, aggression, and other behavioral issues that stem from boredom and lack of mental stimulation. In addition to keeping your kitty’s mind sharp, playtime will keep them fit as a fiddle and in their top form. Regular play sessions help cats balance extra energy, maintain a healthy weight, and prevent obesity-related health issues. It also promotes muscle tone, flexibility, and overall physical fitness, reducing the risk of joint problems as they age.Last but not least, interactive play presents a unique bonding opportunity. Playing together with your cat will strengthen your relationship, fostering trust and affection. It's a chance to spend quality time together and will provide your cat with a sense of security and happiness.How Much Playtime Does My Cat Need?The importance of your cat having regular playtime is indisputable, but how much playtime do they need? Well, as it usually goes with these things, the answer will largely depend on your pet’s specific traits, such as their age, breed, and health status. However, for most cats, that “magic” number ends up being between 20 to 30 minutes of playtime each day. This could be your starting point to determine the right amount of play for your pet, just tailor it to their needs – for instance, younger cats and kittens will need longer and more frequent play sessions to burn off excess energy and engage their curious minds. How To Make Playtime Engaging for Your CatAs intelligent and sometimes finicky animals, cats can be a bit hard to please. A new toy might bore them in a matter of hours, or they might prefer scratching your couch rather than the new cat tree you bought them – but if you rely on the following tricks, it’s much likelier that your kitty will enjoy playtime.#1 Rotate ToysKeep your cat's interest piqued by rotating their toys regularly. Introduce new toys periodically to prevent boredom and stimulate their curiosity, but don’t overdo it – bringing home new toys too often will ensure they get bored of each one too quickly. #2 Variety is KeyExperiment with different types of toys, such as wand toys, laser pointers, puzzle feeders, and interactive play circuits. Cats have unique preferences, so observe what activities your cat enjoys most and tailor playtime accordingly. Usually, a safe bet is going for a catnip-filled toy such as the well-loved  Yeowww! Catnip Yellow Banana Cat Toy. Popular for its shape that makes it perfect for cats to grab onto and forcefully scratch with all fours, this toy will keep your kitty engaged thanks to the organic catnip stuffing that fills this banana-shaped toy to the brim.

New Study Reveals More About How Cats Purr

Pet parents love hearing their cats purr while in a relaxed and blissful state, and it’s believed that a kitty’s purr could be healing, too. But, no matter how long you’ve shared your home with felines, you might still wonder how your furry friend is able to make such a unique sound. New research now sheds some more light on how cats purr, so people can learn even more about their feline companions.

What to Know About Osteoarthritis in Cats

Osteoarthritis, also referred to as OA, is a condition that’s common in cats – experts have found that 90% of kitties over the age of 12 have it. And because cats may hide the signs, it can be overlooked, so it’s a good idea to learn about the symptoms and keep an eye out for them, especially as your pet gets older. The good news is, if your feline friend is diagnosed with this condition, there are things you can do to help her experience less pain.

A New Four-Legged Robot May Soon Replace Guide Dogs

Robots aren’t only taking human jobs! Our four-legged colleagues may soon need new jobs because there’s a new AI-powered robot guide dog in town. Named RoboGuide, the four-legged robot guide dog was born and bred at the University of Glasgow. The research team that created the robotic pooch, says that RoboGuide could help blind and visually impaired people move more freely in indoor spaces. Their new design solves some of the most common problems in assistive tech.“One significant drawback of many current four-legged, two-legged, and wheeled robots is that the technology which allows them to find their way around can limit their usefulness for the visually impaired,” said Olaoluwa Popoola, the project’s principal investigator. “Robots which use GPS to navigate, for example, can perform well outdoors but often struggle in indoor settings, where signal coverage can weaken. Others, which use cameras to ‘see’, are limited by the line of sight, which makes it harder for them to safely guide people around objects or around bends.”To overcome these limitations, the RoboGuide uses a series of sensors that analyze its surroundings. Software created by the team allows the robotic pooch to find optimal routes between locations and interpret sensor data in real-time, so it can avoid hitting obstacles while guiding a blind or visually impaired person.This robotic pooch also obeys its owner. Thanks to large models, RoboGuide understands speech, and can even talk to its handler. The RoboGuide was showcased at the university’s Mazumdar-Shaw Advanced Research Center. The team working on the prototype said that the robotic pooch uses several innovative technologies and that their goal is to release a complete version in the following years.Professor Muhammad Imran, dean of graduate studies at the James Watt School of Engineering and co-investigator on the project said: “Our assistive technology project for the visually impaired embodies innovation, fostering inclusivity.”“In Glasgow, we’re pioneering world-changing technologies that hold the potential to transform lives and reshape societal norms. This achievement was made possible through collaboration with industry and charity partners and co-creating the design with the invaluable input of end users.”The prototype was tested for the first time with volunteers at the Hunterian, Scotland’s oldest museum, in December. During the trial,  the robotic pooch guided the volunteers around the museum and provided interactive speeches on six different exhibits. With an estimated 2.2 billion people in the world living with some form of vision loss, the team hopes to create a commercial product to help guide visually impaired people indoors.“Ultimately, our aim is to develop a complete system which can be adapted for use with robots of all shapes and sizes to help blind and partially sighted people in a wide range of indoor situations,” said Wasim Ahmed, who’s also a co-investigator on the study.  The RoboGuide project is backed by two leading charities. Both the Forth Valley Sensory Centre Trust (FVSC) and the Royal National Institute of Blind People (RNIB) are supporting the development of RoboGuide. “Mobility is a big issue for the blind and partially sighted community,” said Jacquie Winning, the chief executive of FVSC. “RoboGuide is a wonderful solution to that problem, and we are delighted to help test this innovative and creative robot.”James Adams, the director of RNIB Scotland, added: “We’re delighted to be supporting the research and development of technology that could be part of making the world more accessible and empowering blind and partially sighted people to live their lives confidently.”Join the PetGuide community.

How Do I Train My Dog to Wear a Muzzle?

Introducing a new tool to your dog can feel like uncharted territory. While some dogs will readily accept whatever is thrown their way, others will become stressed or anxious when presented with something new. Unfortunately, if you are in a position where a muzzle is necessary for the safety of your dog or others around you, forgoing a tool because your dog appears to be uninterested in it isn’t an option. So, what do you do? How do you train your dog to wear a muzzle? This guide will dig into the importance of conditioning when planning to muzzle your dog. This includes explaining what conditioning is, walking you through the process step-by-step, and sharing some helpful tips to set you up for success. What is Muzzle Conditioning? Before expecting your dog to wear their muzzle, it is recommended that you take the time to focus on muzzle training, also referred to as muzzle conditioning. This is the process of introducing the muzzle alongside positive rewards. If each time your dog sees or interacts with the muzzle, they get “good things,” it will create a positive association. Over time, they will not only tolerate the muzzle but happily accept it. Why? They recognize that wearing their muzzle means they will receive good things like verbal praise, pets, and their favorite treats. How Long Does It Take for a Dog to Get Used to a Muzzle? There is no one guaranteed timeline when working on muzzle conditioning. While some dogs will quickly take to the muzzle, adjusting in just a few days, others will take longer. Some factors that can impact this include your dog’s personality, trainability, previous experience (positive or negative) with a muzzle, and their trust/bond with you as the person introducing this tool to them. It’s important to keep in mind that the time it takes does NOT mean you are doing better or failing at your training efforts. We have three dogs, all of which have been muzzle-trained. While two of our dogs took to the muzzle relatively quickly, Lucifer’s nerves and anxiety made the process more challenging. This doesn’t mean it was impossible. With time, patience, and consistency, he is now the dog that is most comfortable in a muzzle out of the three. We just had to move at his pace.

Survey Finds America’s Most Dog-Friendly Cities, You May Be Surprise

The number of Americans embracing a pet-friendly lifestyle is on the rise, and we’re here for it! We read announcements and news articles daily about businesses introducing pet policies and welcoming our furry friends into their establishments.However, if you’ve been traveling with your pup, you know that not all cities are created equally. Some locations truly shine—not only welcoming dogs but also creating an environment where they can live their lives to the fullest. From dog-friendly patios and shops to beautiful park spaces, these cities are rolling out the red carpet.Interested in finding the best locations for our best friends? MarketWatchGuides studied the country's 98 biggest cities, ranking them based on seven dog-friendly metrics, including:Number of pet activities per 100,000 peopleNumber of dog-friendly restaurants per 100,000 peopleNumber of dog-friendly apartments per 100,000 peopleNumber of dog-friendly weather days (days where the high did not exceed 90 degrees Fahrenheit and the low did not drop below 0 degrees Fahrenheit)Number of dog parks per 100,000 peopleNumber of vet offices per 100,000 peopleAverage vet costsUsing these findings, they gave each city a ranking out of 100 in 3 categories—Dog Friendliness, Dog Walkability, and Pet Health—as well as an overall score out of 100, allowing them to rank the cities from most dog-friendly to least dog-friendly. The findings may have you reconsidering what part of the country you call home!According to the study, Raleigh, North Carolina, was the most dog-friendly city in the United States, with an impressive overall ranking of 80.3. While the city did rank low on a couple of factors (namely, the number of dog-friendly weather days and the number of dog parks), it scored high enough in the other metrics to earn the top spot.Most impressively, the city scored 91.2 on the Pet Health Score, which considered the number of vet offices and average vet costs.Other cities that managed to earn a spot in the top 10 most dog-friendly cities included:Nashville, Tennessee (78.2)Madison, Wisconsin (77.4)Lexington, Kentucky (76.7)Boise, Idaho (76.5)Austin, Texas (74.3)Portland, Oregon (73.9)Cincinnati, Ohio (73.4)Seattle, Washington (72.6)Greensboro, North Carolina (71.1)Of course, ranking these cities on an overall score may not appeal to every dog parent. While one may prioritize finding a city with the lowest vet costs, another may be willing to pay a little more to enjoy a location with more dog-friendly restaurants.Recognizing this, they then broke down a few fun stats to consider:The city with the most dog-friendly restaurants per capita was Orlando, Florida. Meanwhile, on the other end of the spectrum, North Las Vegas, Nevada, took the title of the fewest dog-friendly restaurants per capita.The most accessible pet health care in the United States can be found in Oklahoma City, Oklahoma.Does your dog love heading out for a “Pup Cup” on a warm day? The Starbucks chain first popularized this tasty treat, referring to the small cup of whipped cream as “Puppuccinos.” If the very mention of a Pup Cup has your dog’s tail wagging, you may want to visit Atlanta, Georgia, where you can find the most locations offering pup cups per capita.Wherever your pet-friendly travels take you, check out our list of Dog Travel Essentials to set you (and your dog) up for success!Join the PetGuide community.

Scientists Finally Know Why Cats Love Tuna So Much

No food is more synonymous with cats than tuna. Even the pickiest of cats can’t resist the tuna’s fishy flavor. Finally, scientists have learned why cats love tuna so much. In the study published in the journal Chemical Sense, scientists report that cats, like humans, have receptors needed to detect umami flavor. Along with sweet, sour, bitter, and salty, umami is one of the five basic tastes.Umami seems to be the cats’ favorite flavor. Considering that umami gives food a deep and savory meaty aroma, it’s no surprise that an obligate carnivore like a cat would prefer it over all other flavors.The research team also found that cats’ taste receptors bind to two chemicals found in high concentrations in tuna. These chemicals boost the umami flavor, making cats obsessed with tuna. “This is an important study that will help us better understand the preferences of our familiar pers,” says Yasuka Toda, a molecular biologist at Meiji University. According to Toda, this study could help cat food manufacturers create healthier food and more palatable medication for cats. Previous studies showed that cats have a unique palate. Cats can’t taste sugar, because their sweet receptor gene is dysfunctional. Scientists believe that felines lose the ability to taste sweeteners and carbs because they don’t need these macronutrients to survive. Cats also have fewer bitter flavor receptors than humans. This trait is commonly seen in obligated carnivores. “Since discovering that cats don’t have a functional sweet taste receptor, we did wonder what they would respond to instead,” study lead author Scott McGrane, a sensory science expert at Waltham Petcare Science Institute, told Live Science. Humans and other animals possess two genes - Tas1r1 and Tas1r3 that work together to detect umami flavor. Previous research has shown that cats express the umami-related Tas1r3 gene in their taste buds, but it was unclear whether they possess both genes needed to detect umami flavor. The research team led by McGrane discovered that cats expressed both Tas1r1 and Tas1r3 genes in their taste buds. To learn this, the scientist biopsied the tongue of a six-year-old male cat that had been euthanized for health reasons unrelated to this study. However, a closer look at the protein sequences encoded by these genes showed that they are very different from human genes. As it turned out, the main amino acids that activate umami flavor in people - glutamic and aspartic acid - were mutated in cats. “So I began thinking, maybe cats can’t taste umami,” said McGrane. But, as it turned out, amino acids don’t bind to the cat umami receptor alone. Nucleotides, which are common in meat and yeast, bind to the cat receptor and glutamic and aspartic acid then have an enhancing effect. “That’s the exact opposite of what we see in people,” explained McGrane. Cats love tuna because it contains the nucleotide inosine monophosphate. Tuna also contains large quantities of L-histidine, an essential amino acid for cats, that enhances umami flavor. “The L-histidine content of tuna is much higher than of other fish species and meat sources.”These new findings could be used for the development of tastier cat food and pharmaceuticals. Although cat food manufacturers already knew that cats prefer meaty flavors, they now have much more details about the compounds they can start working with. It’s essential for manufacturers to ensure that animals want to eat the food they formulate and find it appealing. “I think umami is as important for cats as sweet is for humans,” said Toda. Dogs, she explained, can taste both sweet and umami, which may explain why they’re not such fussy eaters. Join the PetGuide community.
