a dogs nose knows how to find expensive truffles

The First Annual International Truffle Expo is happening this weekend in Woodinville, WA, and some pretty amazing dogs and their humans are the highlight of the weekend!

We already know dogs are man’s best friend, and are capable of some incredible hunting. The nose dogs have for scents is indescribable, and two truffle hunters out of Washington are hoping to share their knowledge of truffles, and more specifically truffle hunting in hopes to bring greater awareness of the truffle industry.

Founders of Truffle Dog Co., Kristin Rosenbach and Alana McGee are sharing their many years of canine scent detection and truffle-hunting experiences with truffle enthusiasts, scientists, wine aficionados, foodies, land stewards and of course, dog lovers as they share their vision for a sustainable future for the truffle industry this weekend at the First Annual International Truffle Expo in Woodinville, WA.

Their passion for truffle awareness stems from their love of truffles, which are edible fungi that grow underground and are considered to be diamonds in the culinary world because of their strong and unique food characteristics and aromas, and their love of dogs. The co-founders have seven dogs between them. McGee is a Certified Professional Dog Trainer with over ten years of experience, especially in scent detection and Rosenbach has over 19 years of experience with humans and dogs as a truffle hunter and educator.

Truffles fall in the same category as caviar, saffron and other rare, expensive foods in the world and demand for them is growing in exponential rates. That demand, and their extensive experience with dogs is what inspired McGee and Rosenbach to combine forces and their skill to create the Truffle Dog Co., which trains dogs in scent detection as well as offers guided truffle hunts. In these hunts, participants are led on forays with trained dogs of the Truffle Dog Co., and are able to keep their rare finds or to sell them back to guides if they choose.

Traditionally, pigs were known as truffle hunting dominators, as truffles grow underground and require rooting skills, which pigs are known for. The problem, though, with pigs is that pigs are not as easy to train, and they don’t have endurance that dogs do. Mostly, dogs are better truffle hunters than pigs because their reward is pleasing their guide, whereas a 300-lb pig may bite all your fingers if you tried to wrestle their truffle away.

Truffle Dog Co., also offers global consultations for those interested in getting into the truffle business. With partners in parts of the world including British Columbia and New Zealand, the Truffle Dog Co., helps create sustainable truffle hunting programs and offers unique and science-based methodology for instructing dogs to be the incredible scent hounds they are. As well, they offer online course opportunities if you are interested in training your dog to be a truffle hunter too.

New Research Gives Insight To Why Dogs Are Superior Sniffers

Researchers have found new details about a dog’s anatomy that help explain more why they are such stupendous sniffers! Scientists at Washington University School of Medicine in St. Louis, MO have found new insight as to why dogs have superior senses of smell. They’ve learned more about how a pivotal anatomy difference in their olfactory epithelium development may be the reason they have such an advantage over humans when it comes to smelling things. Related: A Dog’s Nose Knows (How To Find Expensive Truffles) It’s no nose news that dogs’ senses of smell are far better than humans, and the researchers believe that the olfactory epithelium in humans differs in complexity from the olfactory epithelium in dogs, giving them the upper sniff. The olfactory epithelium is a flat tissue that lines the roof of the nasal cavity in humans, but in dogs, it develops more like a maze, with folds and curves over the turbinates in a dog’s nose. The oflactory epithelium has special neurons that attach to odor molecules and give off signals to the brain–that’s what we interpret as smell. Humans have far fewer of these neurons than dogs–hundreds of millions fewer– and so dogs have far more ability to smell things than humans do. Dr. David M. Ornitz is the Alumni Endowed Professor of Developmental Biology with the research and says that they believe the bigger surface area of the olfactory epithelium makes a difference in how well we smell. Dogs are often trained to use that phenomenal sniffing ability to do everything from find drugs, bombs and bed bugs to even finding humans and cancer. The study also may lead to more understanding about the evolution of senses of smells in animals altogether, and to understand why dogs got such better olfactory systems than humans did. Related: A New Generation of Bomb-Sniffing Dogs Picked Based on Brain Scans The team found that a stem cell called FEP controls the size of olfactory epitheliums and they also send signals to turbinates in the nose to tell them to grow. They believe that the signal swapping is where bigger/smaller olfactory systems develop and they’re curious about why the dog’s does so much more than a human’s. Lu M. Yang is a graduate student with the project and said that before their work, no one knew that the epithelium grew from a small patch of cells into a sheet collaboratively with turbinates. This knowledge gives even more insight into the complex turbinate structure of dogs, and eventually maybe in humans.

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.

How to Exercise Your Dog Indoors

Your dog needs daily exercise, but when it’s too cold, snowing, or raining, you shouldn’t let them spend too much time outside; instead, it’s best to bring the fun indoors. Whether you live in an apartment or a large house, there are simple and creative ways to help your canine companion get the physical exercise and mental stimulation they want and need.If you’re stumped when it comes to how to exercise your dog indoors, here are a few ideas to help you get started, along with some product recommendations that are worth considering.Indoor FetchWho says you can’t play fetch with your dog indoors? As long as you have a decent amount of space, you can toss a ball or toy for your pet to chase, grab, and bring back to you. Some people will use a hallway to give their dog enough room to run and grab their toy, but it really depends on your home and its layout. If you don’t have a large room with enough open space, you might need to move some furniture around temporarily, but it will be worth it.A good toy to consider for this is the Chuckit! Indoor Ball. It’s designed specifically for indoor use, and features textured chenille that’s soft and lightweight so you can toss it and let it bounce softly to entice your dog to grab it. Puppies and adult dogs of all sizes are sure to love it, and the multi-layered construction helps it withstand your pet’s teeth so this toy can last.

“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.

A Small Cat Family Was Found Living in the Ceiling of a Restaurant

Cats choose their homes in the unlikeliest of places! And a recent event from Massachusetts, when a momma cat and her four newborn kittens were discovered living in the ceiling of a New Bedford restaurant, definitely confirms this.The  Animal Rescue League of Boston said that they received a call from the employees of a local New Bedford restaurant. It was no ordinary call, however, as the employees said that they were “hearing kittens meowing from the ceiling”. The momma cat, however, was no stranger at the premises. The staff noticed her around the place before but did not suspect that she was pregnant – or that she was living in the ceiling. But hearing the distinct sound of kittens meowing, the employees were quick to understand what happened. The animal rescue team quickly responded to the call, and their field service agents soon spotted the tiny kittens through a small slit between the restaurant wall and a hole in the ceiling. With a little bit of patience and work, the rescue team managed to retrieve all four kittens from the ceiling space, and safely transport them to the rescue shelter. Rescuing the momma cat, however, was not as easy. Cunning and careful, the cat evaded all the efforts of the team, including artificial kitten sounds, and tasty cat food. Ultimately, the team employed a humane cat trap that they placed within the ceiling. The next day, they reported that the momma cat entered the trap at around 11 p.m. at night, which allowed them to reunite her with her children at the Animal Rescue League's Boston Animal Care and Adoption Center. There, they were all treated and given veterinary care."Community cats are incredibly resilient, and have a knack to find shelter for themselves and their offspring," the animal rescue league said in a subsequent statement for  NBC Boston. "However, kittens born this time of year are incredibly vulnerable to the elements and other potential dangers and ARL urges the public that if a cat with offspring are discovered, to contact ARL Field Services for assistance." In the meantime, the happy momma cat and her babies are resting and growing, until the time comes when they can be put up for adoption and find forever homes and each their own happy ending to this unusual story.

Expats May Need to Leave their Pets Behind as Travel Costs Skyrocket

Animal travel has always been expensive, but it’s about to become unaffordable for many pet lovers. Pet owners moving abroad may be forced to leave their pets behind after animal travel costs have gone up by as much as 400 percent!IAG Cargo, a sister company to British Airways, Vueling, and Aer Lingus, has recently announced that it was raising travel prices along some routes beginning March 1. This unexpected move shocked pet owners with relocation plans, particularly those moving to and from Britain and the United States. “To reflect the complexities of this bespoke service and the cost of providing the very best care for pets traveling as cargo, we have made some amendments to our prices,” a spokesperson for IAG Cargo said in a statement. This shipping company is mostly used by military personnel to move their pets abroad while deployed. After three years at their duty station in the UK, Sara and her family are moving back to the U.S. The family’s two dogs, Bentley and Ghost, are booked on a British Airways flight on 1 March.Under the current policy, IAG Cargo only accepts a booking for a pet transfer up to six weeks before the flight. The company then confirms the space has been requested. Two weeks before the flight, once the planes have been scheduled on that route, the IAG Cargo confirms the booking, locking in the price.Initially, Sara’s family was quoted $1,450 for a flight from London to Baltimore for both dogs. However, due to the recent price hike, the travel price for the dogs has jumped to $6,500! And that’s without the administration fees and the cost of the agency the family is using to arrange the cargo shipment. “We are paying out of our own pocket for this, and we just bought a house in our new location,” said Sara to BBC. “Our dogs are like our children, we would do anything for them but that doesn’t mean it’s not devastating for our finances.”The family’s shipping agent found another airline that could ship their dogs at a lower price. The catch - they would have to make a seven-hour round trip to collect the dogs from another airport. Sara explained that her dogs are small in size and that she believes people shipping large-size dogs could face shipping costs over $10,000.“I already know a number of people who did not bring their pets [to the UK] because of the costs to bring them one way… People are going to be shocked,” she added.Details about the new pricing and affected routes are still unclear, but some companies that work with IAG Cargo are already seeing the effects. Kimberly Cirone, a director at Pets Abroad UK, a pet relocation company that assists pet owners with travel arrangements and works with airlines, said that the costs of pet transport between Britain and the United States have increased by 400 percent without warning, consideration, or explanation.The unexpected price hike has left many military families in turmoil as they are unable to gather the necessary funds in time to have their pets shipped back home. “It’s a huge amount to organize, and within days or weeks of arriving one of those family members may be sent on to areas of conflict. The dog or cat is hugely important, it is the family’s companion when one partner is away fighting and this will be hugely distressing for them.”Join the PetGuide community.

Husky Detects a Dangerous Gas Leak and Saves the Entire Neighborhood

Kobe, a four-year-old husky became an internet hero after saving his home and the entire neighborhood from a catastrophic gas leak. According to his owner, Chanell Bell, the canine started digging a large hole in the front yard of their Philadelphia home. At first, Bell didn’t think much of Kobe’s strange behavior. However, as the hole grew bigger, she became concerned that Kobe was trying to tell her something.“I trust his judgment because that isn’t his typical behavior and he is usually right,” said Bell, according to PEOPLE. “He has great senses and he never digs holes unless he is helping me dig; I knew something was up.”Earlier in the month, Bell had a gas leak in the house, and out of caution, she decided to check the hole Kobe dug with a gas detection device. “I had a reader already in the house to make sure there were no leaks coming from my old heater,” explained Bell. “When I saw the hole, I realized it was odd behavior for my dog. My intuition told me to check it.”Immediately the device detected gas. A potentially catastrophic amount of gas was coming from the hole Kobe dug in the yard!Bell alerted authorities right away and they informed her that the entire neighborhood should be grateful that Kobe detected the leak when he did. “We were told it could’ve caused serious health effects like respiratory issues, brain damage, and even death. They told me that something as simple as a light switch turning on could’ve caused an explosion, too.”As soon as they arrived at the address, the gas foreman and crew turned off the gas and started to work on the pipes. During the repairs, the crew discovered three other gas leaks in the neighborhood, all caused by old pipes. The crew worked for three days to repair the leaks and install new pipes. Workers told Bell that something as simple as turning on a light switch could have caused the gas to ignite and blow up the entire house. While they worked, the crew praised Kobe.“They were so impressed with Kobe and mentioned what a good dog he was,” said Bell, adding that people should always listen to their pets and their senses. The gas company said that it adds Marcaptan to the natural gas it administers to homes to produce a smell similar to rotten eggs to allow for easier leak detection. “Just like this customer, any time anyone smells a foreign odor or egg-like smell, they should immediately call,” said the utility company, in a statement. “It feels amazing to know Kobe saved our block, I am very thankful to have him,” added Bell. “I hope this spreads awareness to others about the dangers and severity of gas leaks and to pay attention to your fur babies!”  Join the PetGuide community.

An AI App Helps Vets Diagnose Cats By Detecting Their Pain Levels

Every cat owner has wondered what their cat is thinking about - at least once in a while. You see your feline friend just standing there in the corner, its gaze fixed on something and its expression a true enigma. Sadly, it’s not that easy to read a cat’s emotions, so most of it just remains a mystery. Until now, that is. An Alberta-based company is developing an app that could change the way we see cats and their emotions. The innovative AI app is named Tably, and it aims to help vet clinics assess a cat’s pain more easily. Susan Groenveld, one of the developers of Tably, said that felines visit the vet far less than dogs. "And when you really unpack that, it's because they hide their pain. When a cat is in pain, they go and hide under the bed, versus a dog that'll present to the owner, like kids do," said Groeneveld, the founder at Sylvester.ai, the company developing the  Tably app. "I thought, wouldn't it be cool if everyday people that love their pets would know if their animal may be demonstrating pain."An earlier version of the app already showed remarkable success, with tens of thousands of downloads around the world. Susan Groeneveld said that those early stages of the app acquired around 54,000 downloads in just a week, showing that there is a big need for something like this. "This told us that people were really, really interested in it," she said. "But we really wanted to make sure that it was validated and veterinarians actually supported it because it was a really easy opportunity for us to become a novelty."As the work progressed, the app had been clinically tested by both veterinarians and pet owners in the United States, Canada, as well as in Europe. It is expected that the app will arrive in the digital market in the U.S., Singapore, and France in January. And for Canada, the app should see a release this fall. How does Tably work? The app uses special algorithms that apply standards and facial pain scores that vets previously created. With that, the vets can review the results and better assess the cat’s state. "We believe our technology will make it more accurate because there's less human bias in the subjectivity of the assessment," Groeneveld said.Positive reviews have been overwhelming so far, many of them coming from respected vets. Dr. Liz Ruelle, a vet at the Wild Rose Cat Clinic in Calgary, Alberta, is on the advisory board for the Tably app. Her involvement is very important for the developers, and Dr. Ruelle used the app in her practice. In fact, Dr. Ruelle states that she definitely plans on using the app in her future work and said for  Yahoo: “When a cat experiences pain, its eyes and eyelid positions change and they shift their ear positions. Like if we're in a good mood and we smile, we could think of how our cheeks are uplifted. We see the apples of our cheeks. If I had whiskers on my cheeks, then I would have that same uplifted, happy whiskers," she said. "But when I'm feeling sad, or headache, or painful, then those facial muscles start to sag down … instead of being upright and perky whiskers, they would be kind of dropping down the face."The best thing of all - the app won’t be exclusive to vets. Groeneveld and Ruell stated that a special lite version is planned, which will be aimed at pet owners to use at home. No exact dates have been provided, however.

Pet Obesity Study Shows Promise and Surprising Links With Humans

If you thought that your chubby doggo is incredibly cute, you might want to consider what’s hiding behind that adorable exterior.  Pet obesity is a real thing, and it is a major health hazard that many dogs experience in their lifetime. And, sadly, a lot of it is connected to improper care and diet. To show us just how big of a problem it has become, the latest study from the  Association for Pet Obesity Prevention revealed that in the U.S. alone, around 59% of dogs and 61% of cats were overweight or obese! However, recently conducted research shows that there might be a way to battle the obesity pandemic – with certain strains of probiotics that can help curb pet obesity, especially when dogs are in question. A research team from Seoul National University's Department of Agricultural Biotechnology, College of Agriculture and Life Science, conducted a study investigating the effects of probiotics on canine obesity. They discovered two strains that appeared to have weight-reducing properties in obese dogs. To assess the probiotic potential of these strains, the researchers employed a lifespan analysis using Caenorhabditis elegans, a genetic model known for its simplicity in genetic manipulation and shorter lifespan compared to other animal models. Their findings were detailed in a  paper published in the Microbiology Spectrum journal.Thanks to the positive outcome of this research, a new hope was discovered for doggos struggling with excess weight. The use of Caenorhabditis Elegans offers “interventions aimed at enhancing metabolic health in various mammals”, according to the research team. What is more, the effects could be applied to cats, humans, and other mammals, since C. Elegans “serves as a human homolog model”. In general, this whole study could prove to be beneficial to several animal species, as well as humans, making its significance multifold. However, the exact way that bacteria affects weight is not entirely understood. Even though some studies show that certain strains will slow weight gain, researchers were still unable to find a connection between bacteria and weight.Nevertheless, the study is proving to be a major leap forward when pet obesity is considered. There is plenty of potential in this study, and further efforts could change the way dog obesity is experienced – or possibly even root it out for good! 

Golden Retriever Nurses African Painted Dog Pups Rejected by Their Mom

The Potawatomi Zoo in South Bend, Indiana, recently welcomed a litter of eight endangered African painted dog puppies. After a rough start, only three puppies survived thanks to an unlikely surrogate mother - a golden retriever named Kassy.The Potawatomi Zoo announced that the pair of their African painted dogs, Bleu and Maurice, had a litter of eight puppies born in late September. However, it was soon clear to the care team at the zoo that the pack would not be able to raise the puppies successfully.“Bleu, an inexperienced mother, was not caring for her pups the way she should have, and Maurice was following her lead,” said the zoo. In their natural habitat, African painted dogs live in large packs with unique vocalizations and social dynamics. All adult dogs in the pack work together to help feed and raise the pups. The success of the birth and raising of the pups can be endangered if the pack doesn’t work together as they should. “We knew within 24 hours that we had to separate them,” the zoo’s executive director, Josh Sisk, told the South Bend Tribune. The zoo’s animal care staff consulted with the African Painted Dog Species Survival Plan (SSP), a group of zoo professionals who form the breeding plans for this endangered species in accredited zoos across the United States. The staff at zoos usually try to remain uninvolved, letting the packs raise the puppies as they would in the wild. This approach is often successful and helps the pups learn the complex social structure of their species. However, in this case, the decision was made to intervene and hand-raise the litter. Instead of bottle-feeding the puppies, the SSP recommended finding a surrogate dog to nurse the puppies. Within a few hours, the Indiana Council for Animal Welfare connected the zoo with a golden retriever named Kassy, who recently had a litter of puppies and had milk to spare. Kassy and her litter arrived at the zoo a day after the painted dog pups were born and immediately accepted them. The zoo’s staff watched as Kessy nursed and cared for the pups as if they were her own.“It was a crazy first month,” Sisk said. “Our team was there for four weeks, 24/7. We had a mattress next to the dogs.”The zoo’s veterinarian and care team worked around the clock to ensure that all of the puppies, including Kassy’s litter, were getting enough food and time with Kassy. However, despite everyone’s efforts, not all of the African painted dog pups survived. Four weeks after the litter was born, only three puppies remained. The surviving pups were named Blue, Red, and Orange for the colors staff used to track them since they were born. Originally, the zoo planned to reintegrate the pups with Bleu, Maurice, and Colby. However, the adult dogs didn’t show a positive interest in the pups, so the plan was changed. The zoo decided to build a home for the pups next to adult dogs, so they could still learn how to behave like painted dogs. Once the puppies get older they can either be integrated with Bleu, Maurice, and Colby or moved to another zoo.“Blue, Red, and Orange have had an unusual and challenging start to life, but the zoo hopes they will have a bright and successful future,” the zoo shared in a release. “These three healthy, active pups are just the start of this story and the zoo hopes to share more positive updates of their milestones in the future.”Join the PetGuide community.

Technology Tracking Dogs Really Are a Thing

We’ve all heard of dogs that can sniff out drugs and explosives or locate missing persons from a simple whiff of their clothing… but what’s all this about technology trackers? Can I seriously teach my pooch to hunt down the TV remote that went missing over the weekend? Actually, it’s not that kind of technology. You see, this highly specialized dog is trained to detect a compound called triphenylphosphine oxide (TPPO) and with a dog’s approximately 400 million olfactory receptors (humans have closer to 50 million) these super sleuths can smell that stuff through pocket material, duffle bags, a shoe insole, and even drywall. Now, if you’re wondering what TPPO is, it’s the compound used to cover circuit boards in storage devices ranging from hard drives to USB sticks, memory cards and even those tiny SIM cards that store data on our cellphones. Essentially, it’s the all-important coating that prevents these gadgets from overheating and because of that, it’s a compound that will never not be present on electronic devices.But as to why this specific training is growing in K9 units worldwide you need to consider the increase in cyber-terrorism. From drug and human trafficking to child pornography and weapons offences, the need to locate a criminal’s “tools of the trade” such as computers, burner phones, and hard drives is essential to securing a successful conviction. And while internet use and location trackers have made it easy to trail an individual, many perpetrators now work on darknets – an overlay that uses the internet but requires special software for the person to access illicit data.Of course, even a darknet involves a computer system and that’s where the TPPO-sniffing pooch steps up to the plate. Find the perp and let this specially trained K9 agent track down the concealed storage system. I mean, when you’re dealing with something as easily hidden as a SIM card, having a secret furry weapon that detects the scent, then sits, barks and wags his tail saves a heck of a lot of time.Truth is, technology-tracking dogs are becoming more and more common in the execution of this type of warrant because police often get just one shot at finding the much-needed evidence. No surprise that the best dogs for this type of work tend to be the usual suspects – Labrador retrievers because of their heightened sensory skills, innate hunting traits and their gentle disposition – important if there are younger family members present during a search. Other faves include the stately Belgian Malinois and German Shepherd dogs for their tenacity and handler loyalty. I’m not convinced my Schnoodles would rank but as with most family pooches, they’re ace at hunting down an errant chip between the sofa cushions… and that’s good enough for me.

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.

How To Tell if a Dog Is Cold

You might think your dog feels fine in cold weather, thanks to their thick coat, but they can definitely feel the chill—and when they aren’t warm and comfortable, they could develop serious problems like hypothermia. So, it’s important to know the signs that your dog is cold, and to take steps to keep your pet comfy, whether they’re indoors or outside.  Although any dog can be affected by cold temperatures, wind, and snow, some are going to feel the drop in temperature sooner or more intensely. Puppies and seniors, as well as small dogs and those with short coats, are a few examples, along with hairless dogs and those who are ill or have chronic medical conditions.Signs Your Dog Is ColdHere are some of the ways to tell if your dog is cold:Your dog feels cold to the touch – An easy way to tell if your dog is cold is by petting them and feeling the temperature of their body. A good place to check is their ears, but also touch their paws, belly, and skin under their fur. If their body is cool to the touch, there are ways to warm them up.Your dog doesn’t want to be active – If your dog isn’t as active as they usually are, they might be feeling the chill in the air. Feel their body, as discussed above, to see if they’re cold, and take steps to make them warm. A dog who’s moving more slowly than normal while outside should be brought inside right away. Your dog is shivering – Just like people shiver when they’re cold, dogs will too, so this is an obvious sign that your pet needs to be warmed up as soon as possible. If your dog is trembling, consider the temperature inside your home, as you might need to turn the heat up. And if your dog is shaking while outside in the cold, bring them inside right away.Your dog is searching for ways to stay warm – If your dog wants to lie down next to the fireplace or heater, or they want to snuggle up next to you or under a blanket, they’re looking for ways to get warm. In addition, your dog might be reluctant to go outside, whether for a walk or to go potty. If they’re outside and you see them trying to find some shelter to warm up, bring them in immediately.  Your dog’s body language and vocalizations change – If you know your pet’s normal behavior and demeanor, it should be easy to tell when they’re cold. There will be signs that they’re uncomfortable, and they might exhibit anxious behaviors that let you know something is wrong. For example, your dog may tuck their tail, have a hunched posture, or curl up in a ball, and they might also bark or whimper. What To Do if Your Dog Is ColdWhenever your dog is showing signs of feeling cold, take action right away. Remember, a dog who gets too cold is at risk of hypothermia. Also, the cold can make some dogs, such as those with arthritis, experience even more discomfort. If your dog is outside, bring them inside.
