Damselfish General description

Damselfish are a colorful species of saltwater fish extremely popular in the modern saltwater aquarium hobby. Their small size, hardy nature and high availability have made them a popular choice of fish for new aquariums. Tank raised varieties are readily available in pet stores and aquariums and are significantly hardier than their wild-caught counterparts.

Damselfish are a colorful species of saltwater fish extremely popular in the modern saltwater aquarium hobby.

Origins

Damselfishes originate from tropical coral reefs around the world.

Color

Most species are vibrantly colored and come in shades of blue, yellow, red, orange, black and white.

Maintenance and care

Damselfish are capable of adapting to a wide range of aquarium conditions. Most species of damselfish only grow up to a couple of inches in length so can be housed in small to medium-sized aquariums. Damselfish also do best when kept in groups of 4 or more and can be kept in even larger groups when provided with adequate space. They can however turn aggressive and territorial towards other species of fish as they age; especially fish that are introduced later on to an aquarium. This is sometimes a concern when using damsels as starter fish to cycle an aquarium.

Damselfish do best in aquariums with open swimming spaces as well as plenty of hiding places. Each damselfish will establish and guard its own territory with one or more hiding places.

Feeding

Damselfishes are omnivores and will readily accept flake based foods as well as live and frozen foods. However, it is important to research the specific dietary requirements of individual species. For example, certain species are herbivores.

Damselfish are capable of adapting to a wide range of aquarium conditions.

Breeding

Damselfish have been successfully bred and raised in aquariums. When spawning, males will often court a number of females and entice them to lay eggs in their nesting sites. They will care for all the eggs laid in their nest, but do sometimes devour younger eggs so they can devote their parental efforts to the more mature eggs which are closer to hatching. Males engage in a frantic mating dance where they swim up and down in a column, emitting a pulse which indicates their vigor to potential females. The females choose their partners based on the speed and vigor of the males’ mating dance.

Aquarium varieties

Yellowtail Damselfishes, Blue Damselfishes, Three Stripe Damselfishes, Blue and Gold Damselfishes, Neon Damselfishes, Tracey’s Damselfishes, etc.

Let's Talk Turkey... and Why the White House Pardons One Each Year

It’s now a Thanksgiving tradition… and we’re not talking about the Macy’s parade, the Black Friday sales or that cranberry chutney Aunt Sally whips up each year. We’re talking about the turkey pardon that according to the White House Historical Association, is rumored to have begun back in 1863 with then-President Lincoln. Whether this tale is fact or fiction is debated. What we know is that more recent history confirms the big bird officially began as a gift made to the White House by The National Turkey Federation back in 1947. Alas, no details on his outcome.This year, President Biden pardoned two 42-pounders, preventing them from being on the wrong side of the Thanksgiving feast when he gave Liberty and Bell, a pass and a certain cushy future.As mentioned, this fun seasonal practice began in 1947 and over the years tended to be rather on-again/off-again depending on the whims of whichever administration was in place. It wasn’t until the Kennedy era in the early ‘60s that Tom Turkey was formally spared and lived to see another day. Since then, the support to spare this fine feathered fowl has ramped up considerably and his well-being post-pardon was carefully tracked by both the media and animal rights groups throughout the country.Was it just for show? Did he really make his exit from the White House intact versus being basted, carved and covered in gravy?Before I answer, let’s just say that the fun spin on this tradition is how it has evolved. Not only did Liberty and Bell enjoy a stay in a suite at the luxe Willard Intercontinental Hotel the night before their widely shared pardon, but following their moment in the spotlight, they returned home to Minnesota where the state’s College of Food, Agriculture and Natural Resources Sciences will oversee their care.So, yes. Beginning with the Bush administration in 1989, the turkey pardon became a tradition that sees one lucky bird truly pardoned and destined for a life of ease and indulgence.In fact, past White House pardons have typically resulted in said turkey being relocated to a local children’s farm where they can live out their remaining years being adored by the junior crowd and noshing down on kibble from a cone. BTW, did you know that a turkey can live to 10 years of age?Of course, now we’re all feeling warm and sentimental about turkeys, the inevitable question arises: Can a turkey be kept as a pet? The short answer is yes, these highly social critters enjoy the company of humans and can be curious, vocal, and entertaining.  So much so that they’re a top pick for hobby farmers and those who have already ventured into keeping chickens.Just a little food for thought!

What Is Scent Enrichment for Cats?

Your cat has a powerful sense of smell that she uses to navigate her surroundings and make decisions, so it’s important to consider your kitty when using scented products around the house and maintaining a litter box that doesn’t have offensive odors.In addition to considering the fragrances that can be off-putting to your kitty, you can also enrich your cat’s environment and make her daily life more fun with scent. Below are some tips on how to use scent enrichment to keep your furbaby happy.

Do Dogs Experience Grief?

Anyone who has ever shared their heart and home with a dog can attest to how deep the emotional connection we form with our best friends is. It is this bond that makes saying goodbye so difficult. But are we the only ones experiencing this pain?If you have recently experienced the passing of a pet or family member and noticed your dog acting a little differently, you may be wondering – Do dogs experience grief, too?In this article, we will dig into the truth about canine emotions and canine grief. This includes understanding what grief means to your dog, learning to recognize the signs that they may be mourning and tips for helping your best friend navigate this difficult time.Do Dogs Experience Grief or Mourning?The short answer is yes, dogs do grieve the loss of a person or animal in their lives. In a 2022 study led by Dr. Federica Pirrone, a veterinary physiologist at the University of Milan, 86% of dog owners reported that they saw a change in behavior in their surviving dog after losing a companion.Our dogs form close bonds with one another and with us. This can be seen both in wild dogs, with the relationships that exist between pack members, as well as the domesticated dogs of today.While they can’t tell us how they are feeling (although we wish they could), dog parents often witness physical and behavioral changes that indicate something is “off” for their dog following a loss. This occurs when a family member (human or pet) passes or even if a family member moves away like a child moving out of the family home.Recognizing that our dogs also go through a grieving process allows us to take steps to help our beloved furry friends deal with this difficult time.

Enigmatic Respiratory Illness Targets Dogs – These Are The Symptoms

A mysterious and seemingly quite dangerous dog respiratory illness is spreading across the United States– and has veterinarians perplexed. This illness is compared to pneumonia, as it starts with coughing and gradually worsens. To make matters even worse, the illness seems to be resistant to common antibiotics.Officials are now releasing  statements that say dogs are most likely to contract this enigmatic illness directly through contact with other dogs. What this means is that the danger lurks in dog parks, grooming salons, kennels, and any other place where a lot of dogs can be found.While there are some enigmatic aspects to the disease, there are ways, luckily, to recognize it quickly. The most common symptoms to keep an eye out for are coughing, trouble breathing, wheezing, sneezing, nasal and eye discharge, fatigue, lethargy, and so on. According to the Oregon Department of Agriculture, dogs who exhibit these symptoms may also test negative for common causes of respiratory illnesses. Needless to say, owners who spot these symptoms in their dogs should go to the vet immediately. In the meantime, vets are advising owners to avoid places with a lot of dogs for the time being, and also to make sure that their pets are “up to date” with all the necessary vaccinations. And although it is a new illness, officials at the Oregon Department of Agriculture have said that three main categories of cases can already be observed.Chronic mild-moderate tracheobronchitis with a prolonged duration (6 to 8 weeks or longer) that is minimally or not responsive to antibiotics. Chronic pneumonia that is minimally or not responsive to antibiotics.Acute pneumonia rapidly becomes severe and often leads to poor outcomes in as little as 24-36 hours.Checkups are advised, of course, and vets urge owners to schedule visits before exposing their dogs to potentially dangerous environments. According to officials, the illness had been reported in the following U.S. states: Washington, Idaho, Illinois, California, Indiana, Florida, Georgia, Colorado, Oregon, and New Hampshire.“Reduce contact with large numbers of unknown dogs.” the officials advise. “Just like with other respiratory pathogens, the more contacts your dog has, the greater the risk of encountering a dog that’s infectious.”While experts advise dog owners to be careful, but not to worry too much without a reason. Needless to say, you should avoid contact with dogs that look sick or exhibit symptoms such as coughing, wheezing, or runny nose and eyes. Do your best to keep your dog away from them. Another thing to avoid is communal water sources from which many dogs drink. And if your four-legged friend exhibits these symptoms, make sure to keep them at home in order to keep other dogs safe – and of course contact a vet to make sure they get the right treatment on time.

Rescues and dog experts alike felt solution to separation anxiety was a total fumble. Can they recover this year?

Pandemic Puppies Are Behaving Badly, Study Shows

Puppies bought during the COVID-19 pandemic are more likely to exhibit one or more problem behaviors, a new study suggests. Research by the Royal Veterinary Colledge (RVC) has found that four in five (82%) owners of pandemic puppies have resorted to using punishment-based training methods to try to curb their dog’s problem behavior. The study found that moving the dog or shouting at them were the most commonly used aversive training methods. Other owners reported using water pistols, rattle bottles, and choke chains. Only 18% of owners who participated in the study said they didn’t use any aversive training methods or aids. Not only are aversive training techniques such as yelling at the dog or pulling its lead ineffective but they are also linked to further behavioral problems. The survey which was funded by the Battersea animal rescue charity asked more than 1,007 UK dog owners to list problem behaviors exhibited by their dogs. The list consisted of 24 problem behaviors reported by the owners. They ranged from control behaviors ( pulling on the leash) and attention-seeking behaviors, to aggressive behaviors and fear behaviors (anxiety around other dogs or people).Almost all (97%) owners said their dog exhibited at least one problem behavior from the list. At 21 months, owners on average reported five behavioral problems, while 20% of owners reported that their dogs had eight or more problem behaviors. According to owners, pulling on the leash is the most common problem behavior (67%), followed by jumping on people (57%), and not coming back when called (52%).Denise Mariner-Chappell got a Labrador retriever Ted during the pandemic. Strict lockdown measures made it hard to properly train and socialize her new pooch.“He’s a crazy dog when he’s out,” she said. “He’s just manic. He just wants to play and sniff, and everything, but not with humans.” Dr. Rowena Packer, the lead author of the study explained that problem behaviors are very common in pandemic puppies. In many cases, owners exacerbate these issues by using punishment-based training methods. “Although we understand these problem behaviors can be very frustrating for owners, they are often a sign a dog is struggling to cope or that they haven’t been taught an appropriate response in a situation, rather than dogs intentionally behaving badly,” she added.Packer warned that punishing the dog can make it anxious and fearful and cause it to develop further behavioral problems, including aggression. According to Robert Bays, Battersea’s senior animal behavior manager, the charity has seen an influx in dogs with behavioral problems coming into centers. These pups are suffering from separation anxiety and show other problem behaviors, which can be linked to training challenges brought on by the pandemic. “Without the right kind of positive training and support, a small behavioral problem in a puppy or a dog can quickly escalate into a serious issue, so we are deeply concerned with this study’s findings that so many owners are using aversive training methods,” said Bays.This training approach can cause additional behavioral problems in adulthood and also significantly damage the relationship between the dog and its owner. The study found that puppies who were still exhibiting problem behaviors by the age of 21 months were at a higher risk of being rehomed or euthanized. “A key piece of guidance arising from our study is that attending puppy classes is a vital way to support owners in using the best training techniques available.”Although many pandemic puppy owners missed these training classes due to lockdown restrictions there are thankfully many certified trainers who offer training classes for adult dogs. Join the PetGuide community.

Human-Cat Amputee Duo Teams Up To Help Others Through Animal Therapy

Juanita Mengel from Amanda, Ohio, and her five-year-old dilute tortoiseshell cat Lola-Pearl, make a unique therapy team. The 67-year-old Mengel is missing a leg, and her fluffy feline is missing a left hind leg. This special duo is one of an estimated 200 therapy cat teams registered in the US through Pet Partners. This nonprofit organization puts together owners and their pets as volunteer teams. They aim to provide animal-assisted therapy in hospitals, nursing homes, and schools. “A therapy animal is an animal who’s been assessed based on their ability to meet new people and not just tolerate the interaction but actively enjoy it,” said Taylor Chastain Griffin, the national director of animal-assisted interventions advancement at Pet Partners. This organization registered nine different species of animals as therapy animals, including dogs, cats, rabbits, guinea pigs, rats, birds, horses, mini pigs, alpacas, and lamas. Therapy cats are less common than therapy dogs, and people are often surprised to see cats in this role. However, Griffin studies the impact of therapy cats and emphasizes the importance of cats in therapy teams. There’s a lot of research on other therapy animals, especially dogs, so there is often a ‘shock factor’ associated with therapy cats because many people don’t know these felines exist. “They go into a setting and people are like ‘Whoa, there’s a cat on a leash. What’s happening?’” said Griffin. According to her, cats inspire people to connect to them in a way that’s not seen with other kinds of therapy animals. Juanita Mengel knew that her cat Lola-Pear would be an excellent therapy animal a month after she adopted her. The feline’s therapeutic potential became clear after Mengel took her to an amputee conference. “She was so good with people I just knew she would be a good therapy cat,” said Mengel. “People really were attracted to her, too.”During a recent limb loss support group, Mengel pushed Lola-Pearl around in a cat stroller labeled “Therapy Cat’, so participants could pet the cat as she woke from a nap. When she wasn’t sitting in a stroller, Lola-Pearl could be found brushing against participants’ legs or cuddling in their laps, bringing a smile to the face of every person she decided was worthy of her company. “She’s very intuitive of people,” said Mengel.Although Lola-Pearl is very special, she isn’t the only cat Mengel owns. Mengel, who lost her leg after years of surgeries following a near-fatal car accident, is a mom to seven cats, most of whom have disabilities. “They find you, you don’t find them,” she added.Lola-Pearl was only a few weeks old when she was found with her back legs completely twisted together. The kitten was unable to walk and was brought to Mengel’s friend at a shelter in Missouri. Unfortunately, the vets there couldn’t help the feline. The shelter located a specialist in Iowa who was able to splint Lola-Pearl’s legs in order to save them. However, it was clear that the left hind leg was beyond saving and the vets decided to amputate. Mengel adopted Lola-Pearl after she recovered from the surgery and they formed the unique therapy team. After everything Mengel has been through, she is extremely grateful for Lola-Pearl and appreciates all the good work they do together. “It’s a really rewarding experience,” she said. “I get just as much out of it as the people that I visit.” Join the PetGuide community.

Can Cats Get Frostbite?

When a cat is exposed to extremely cold conditions, they are at risk of frostbite, which may require professional veterinary care. But what is frostbite, what puts a cat at risk of frostbite, and what can be done to treat it? Here’s a short guide to help you better understand this condition and keep your cat safe.

How Can I Tell If My Dog Has a Fever?

High fever is no joke, and can be quite serious – both for people and their furry four-legged friends. Yes, dogs can have a fever too, and it can be a much more serious condition for them than it is for us. Unfortunately, fever is not an ailment you can spot with your bare eye. Because of this, you will need to thoroughly observe your pet’s behavior and learn how to spot those little details that indicate a fever. Read on as we go through the basics of dog fever and just how to tell if your pet needs your help.Symptoms of Fever in DogsDogs, like humans, can develop a fever as a response to illness or infection. It’s the body’s natural way to fight off the “intruders” in the body. Fever comes in many forms and for various reasons. You can tell if your dog has a fever by observing their behavior and checking for physical signs. Here are just a few of the most common indicators.Increased Body Temperature: 

Are Squeaky Toys Safe for Dogs?

When it comes to dog toys that engage and entertain – squeaky toys are a tried and true classic that fits the bill perfectly. While most dogs love the high-pitched tones these chewable and squeezable toys produce, some owners are not as thrilled and are wondering if there are any potential dangers when it comes to squeaky toys. Could the squeaker come off and pose a choking hazard, or can mold build up inside the hollow center, etc? These are all valid questions, so let’s see what the answers are. Are Squeaky Toys Safe for Dogs? Safety Concerns To Have In MindSafety should always be paramount when it comes to choosing toys for your furry friend, especially when it comes to squeaky toys. Not every squeaky toy is created equal, and some may pose risks to your canine companion. Before selecting a squeaky toy, it's crucial to consider several safety factors.Firstly, pay close attention to the material of the toy. Opt for squeaky toys made from durable, non-toxic materials. Avoid toys with small parts that could be easily chewed off and swallowed, as this could lead to potential choking hazards. Ideally, the squeaker should be highly inaccessible, such as is the case in these  Multipet Loofa Dog Toys with a hidden internal squeaker. The long tubular body of the toy concealed the squeaker and is also super fun for pooches to carry and toss around.

A Former Elvis Impersonator Adopts Elvis, the Dog Who No One Wanted

Elvis, the only dog who didn’t get adopted at Anti Cruelty’s Fall in Love adoption event, finally found a forever home with an owner who used to work as an Elvis Presley impersonator. A three-year-old pit bull terrier mix was the only pooch out of 22 dogs and 39 cats who didn’t find a forever home at the November 11 adoption event. After the event, Elvis had to be sent back to his kennel which served as his home for around four months.Shortly after the event, the shelter took to social media to ask for help finding this handsome boy a forever home. The post that has gone viral said: “Elvis is the only dog that didn’t find a home during our Fall in Love adoption event. He met a lot of potential adopters but sadly did not get adopted. Help us find Elvis a family to love!”In the post, the shelter described Elvis as a “three-year-old meatball” with “the silliest personality.”“His giant smile lights up every room he enters. Elvis is a snuggler, so he hopes you’re okay giving up your personal space.”Elvis arrived at the shelter as an injured stray dog. Since the pooch didn’t put weight on his hind leg, the shelter took X-rays which showed a fractured pelvis. Although the fracture healed completely during his stay at the shelter, Elvis might be prone to arthritis in the future. A few days later this handsome boy found his forever home! And this is where things get really interesting. The couple who adopted the cute pup has a special connection to him - one of them used to be an Elvis Presley impersonator.Loren Agron, one of the pup’s new dads, worked as an Elvis-impersonating waiter at Ed Debevic’s, a 1950s-themed diner where staff entertained customers with choreographed dance routines. Agron dressed up as Elvis Presley and called himself Elvis Parsley.“I wore a black cowboy shirt and quintessential giant Elvis sunglasses, I had long sideburns and my hair was all pumped up and slicked back,” Agron told The Washington Post.“Elvis has always been a big part of my life because I’ve always loved music from that era,” he added.First, Agron went to the shelter to meet Elvis alone, and then he came back with his partner, Drew Wilhelm. “While we were sitting in the waiting room to meet him, I felt like a father waiting for his newborn son to arrive,” said Wilhelm. “As soon as I saw him, I knew that was our dog,” he added. “He couldn’t stop jumping on us, he was so excited we were there to see him.”The couple adopted Elvis that day and took him to his forever home.  “Elvis has left the building,” the shelter wrote alongside a photo of the happy family. “His adopters have been waiting for the right time to welcome a dog into their family, and once they saw Elvis on the news, they couldn’t deny that it was fate.”The couple plans to keep the handsome pup’s legendary name and smitten with their new four-legged companion. “The couple is head over heels in love with their new family member and already has a dog bed and tons of toys waiting for him at his forever home,” the shelter wrote in a post. “Loren is a dedicated ACS supporter and has hosted many of the ACS’s fundraising events at Chicago’s fabulous drag queen, Debbie Fox. We couldn’t be happier for Elvis who finally got his happily ever after!”Join the PetGuide community. Get the latest pet news and product recommendations by subscribing to our newsletter here.

“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.

This Special Camera Reveals How Our Pets See the World Around Them

Have you ever wondered how your pet  sees the world around them? We all know that the eyes of dogs, cats, and all other animals are not the same as ours, and they often see the world in a very different way. While all we could do is imagine and theorize up until now, thanks to a new breakthrough in technology we will be able to take a peek through the eyes of animals!Scientists have  invented a special camera that uses a unique combination of state-of-the-art hardware and software, in order to create videos and images that show us exactly how certain animals see. For example, with this latest tech, you will be able to see the vivid world of colors that are seen through the eyes of birds and bees. One of the recent demonstrations revealed how a UV-sensitive vision of a bird renders an orange sulfur butterfly - the result is more than striking, as it doesn’t look like anything related to human vision.

New Study Searches for the Secret Connection Between ‘Gifted’ Dogs

As dog parents, we all want to believe that our dog is the smartest, most incredible, most amazing dog out there. Right? But there is a select group of dogs whose talent and intelligence stand out above the rest. What makes these dogs so bright? That’s what a new study hopes to understand… Known as “Gifted Word Learner” (GWL) Dogs, these dogs display an impressive vocabulary by learning the names of dozens of their toys, with some learning as many as 125 toys by name! Interested in better understanding this phenomenon and what makes these dogs so naturally gifted, researchers at Eötvös Loránd University in Hungary set out to identify any commonalities between these pups. Their recent study, published in Scientific Reports on December 14, included 41 GWL dogs from nine countries: the US, the UK, Canada, Brazil, Norway, Netherlands, Spain, Portugal, and Hungary. They put out a call for ‘gifted’ dogs, asking owners to complete and submit a self-assessment following their detailed instructions and send the results in a video. Dogs that passed that phase were then given an online vocabulary assessment test to better assess their language skills. The owners were also given a questionnaire to provide a better understanding of each dog’s life experience. “In the questionnaire, we asked the owners about their dog’s life experience, their own experience in raising and training dogs, and about the process by which the dog came to learn the names of his/her toys,” explained Dr. Andrea Sommese, study co-author. Researchers discovered some interesting connections between the GWL dogs using all this information.

Researchers Find Genetic Links Between Human and Canine Brain Tumors

In a groundbreaking study, researchers have discovered striking similarities between the most common type of brain tumor in dogs and humans - meningioma. These findings were published in the scientific journal Acta Neuropathologica. Until now, scientists struggled to find reliable experimental models to understand the biology of and develop effective treatments for these tumors. But thanks to these newly discovered similarities, doctors will be able to use a classification system that identifies these aggressive tumors in humans and pooches.“The discovery that naturally occurring canine tumors closely resemble their human counterparts opens numerous avenues of exploring the biology of these challenging tumors,” said Dr. Akash Patel, an associate professor of neurosurgery at Baylor College of Medicine and principal investigator at the Jan and Dan Duncan Neurological Research Institute (Duncan NRI) at Texas Children’s Hospital. “It also provides opportunities for developing and studying novel treatments applicable to both humans and dogs,” he added.During the study, researchers analyzed 62 dog meningiomas from 27 breeds and found that the tumors were remarkably similar to the same kinds of tumors in humans. To this date, this is the largest study of the gene expression profiles of the canine meningioma. Others, including Dr. Jonathan Levine, a VMBS professor and the head of the Department of Small Animal Clinical Sciences (VSCS), and Dr. Tiemo Klisch, assistant professor at Baylor College of Medicine and Principal Investigator at Duncan NRI, were involved in the study along Dr. Patel. Meanwhile, assistant professor Dr. Beth Boudreau was a key collaborator. Previous work done by Levine, Boudreau, and others at VMBS, which found similarities between gliomas - the second most common type of brain tumors - in humans and dogs, was instrumental for Patel’s study. “We ended up agreeing to provide Patel with canine tumor samples we had worked years and years to achieve, to see if he could isolate the RNA, which is not always easy to do,” said Levine, in a statement. “He was able to produce this very robust data set that showed a similar pattern structure to human tumors. Our team also provided Dr. Patel with key clinical outcome data, including responses to certain treatments.”Now that the researchers have found a link between brain tumors in humans and dogs they hope to establish clinical trials to continue their research. Setting up this type of clinical trial can take several years of planning and requires funding.“We are really interested in creating wins for both human and animal medicine,” said Levine. “For example, we hope to give dog owners access to therapy that’s not available anywhere else in the world through clinical trials. At the same time, that information will also inform the next step of human trials.”As it happens, another group of researchers from the University of California, Davis, conducted a similar study with matching results about meningioma in humans and dogs. This study was also published in the scientific journal Acta Neuropathologica.Now, the two research groups plan to collaborate in the future and share their findings to develop treatment options for both human and canine brain tumors. “If we do one trial, we’d be able to enroll patients a lot more quickly, which would make it easier to get larger data sets resulting in stronger findings. So we have a lot of interest in doing a collaborative trial,” added Levine. “We really see the team out in California as potential partners.” Thanks to this groundbreaking research, scientists now have a better understanding of brain tumors and are one step closer to developing life-saving treatments for both humans and dogs. Join the PetGuide community.

What is a Hydrolyzed Protein Diet for Dogs?

Protein is a very important part of a dog’s diet. However, some doggos might have a sensitive digestive system or even allergies. In such cases, a hydrolyzed protein diet becomes essential as it provides important nutrients without being heavy on their tummy. But what is hydrolyzed protein exactly? A hydrolyzed protein diet for dogs is a type of food that is formulated specifically for dogs that have allergies or certain food sensitivities. The protein sources in this diet are all broken down into smaller molecules, thanks to a complex process called hydrolysis. What this process does is reduce the size of the protein molecules, making them less likely to trigger an allergic reaction. So, if your doggo is a bit sensitive, this could be what’s needed!Veterinarians often recommend hydrolyzed protein for dogs that are diagnosed with intolerances or  food allergies. Thanks to this, your pet can receive all the essential nutrients without any adverse reactions being triggered. The most common sources of hydrolyzed protein in these diets are beef, chicken, salmon, or soy. So it’s just like most of the common dog foods - but in a different, better form. 

AI Could Match You with a New Furry Friend Based on Personality

In a cutting-edge study, scientists specializing in canine behavior have used artificial intelligence to predict dog personality types. A multi-disciplinary research team has developed an AI algorithm that simplifies the painstaking process of evaluating canine personalities.Understanding a dog’s temperament is key not only for pet owners but also for training agencies and professionals working with working dogs. The study, which introduces a brand-new method of predicting and categorizing dog personalities, is published in the eminent journal Scientific Reports. The team that developed the algorithm hopes that it will more quickly and accurately evaluate which dogs are better suited for long-term careers, such as assisting people with disabilities and helping law enforcement. This new approach to predicting dog personalities could also be used to match owners with a new furry best friend. The new AI algorithm can help shelters place dogs in the right homes, thus reducing the number of dogs returned for not being the right fit for their adoptive families.Before this algorithm, canine behavioral experts used questionnaires and statistical analysis to determine a dog’s personality.  The AI algorithm uses data from almost 8,000 responses to the commonly used Canine Behavioral Assessment and Research Questionnaire (C-BARQ). The C-BARQ questionnaire has been the top resource for evaluating working dogs in the past two decades. “C-BARQ is highly effective, but many of its questions are also subjective,” said James Serpell, a professor of ethics and animal welfare emeritus at the University of Pennsylvania School of Veterinary Medicine. “By clustering data from thousands of surveys, we can adjust for outlying responses inherent to subjective survey questions in categories such as dog rivalry and stranger-related fear.”The team’s new AI algorithm gathers the responses to C-BARQ questions into five main categories that essentially form the digital personality of a dog. The results showed five distinctive personality types among domestic dogs, including excitable/attached, anxious/fearful, reactive/assertive, aloof/predatory, and calm/agreeable.The study was conducted over two years by a multi-disciplinary research team consisting of Dr Mohammad Amirhosseini of the University of East London and Professor James Serpell of the University of Pennsylvania School of Veterinary Medicine. The research was sponsored by Dogvatar, a Miami, Florida-based canine technology startup.“This innovative AI-based methodology holds promise for revolutionizing the selection and training of dogs for specific roles, both for working and non-working,” said Dr Amirhosseini. Almost 50 percent of people who surrender their dogs to animal shelters in the USA say that behavioral problems are a contributing factor, and nearly a quarter say that those problems are the main reason for giving up their dog. More research is needed to understand the nuances of canine personalities. However, researchers hope to promote strong bonds between people and their dogs by designing effective training programs and customized dog-owner interactions. According to researchers, these findings could serve as a foundation to explore personality matching between dogs and their owners and how that might improve the quality of their relationship.Dogvatar and the research team plan to conduct further research into potential uses for their dog personality testing algorithm.“This has been a really exciting breakthrough for us,” said Dogvatar CEO Piya Pettigrew. “This algorithm could greatly improve efficiency in working dog training and placement process and could help reduce the number of companion dogs brought back to shelters for not being compatible. It’s a win for both dogs and the people they serve.” Join the PetGuide community. Get the latest pet news and product recommendations by subscribing to our newsletter here.
