Bears are evolutionarily closer to dogs than cats because both bears (Ursidae) and dogs (Canidae) belong to the suborder Caniformia (dog-like carnivores), while cats are in the suborder Feliformia (cat-like carnivores). Millions of years ago, all carnivores split into these two main branches, with bears and dogs sharing a more recent common ancestor than either shares with cats, making them "cousins" in the carnivore family tree.
Chow Chow. The chow chow is a breed hailing from ancient China. A thick mane (or ruff) makes these dogs appear particularly cute and cuddly (and bear-like), and they are also muscular and deep-chested with an overall furry coat.
The closest relatives to bears are seals, sea lions and walrus. Pinnipeds (the name given to the scientific order for seals, sea lions and walrus) are the sea-going cousins of bears.
Scientists think that beardogs diverged from other caniforms early on, forming their own branch of the mammal family tree. Both bears and dogs evolved later. But today, they are the beardogs' closest living relatives. And because of that, beardogs share a lot of similarities with both animals.
Humans Share Portions of DNA with Pets
Humans and cats share almost 90%. These high percentages of similarities make genetic sequencing in all three species mutually beneficial. Advancements in both human DNA testing and pet DNA testing can potentially be applied across species.
The top "silent killers" in cats are Chronic Kidney Disease (CKD), often progressing until 75% kidney failure, and Hypertrophic Cardiomyopathy (HCM), a heart muscle disease, both often showing few symptoms until advanced stages, along with Hypertension (High Blood Pressure) and Hepatic Lipidosis (Fatty Liver), leading to sudden illness or organ failure if undetected. Early detection through regular vet check-ups, blood tests, and monitoring for subtle changes like increased thirst/urination, weight loss, or hiding is crucial for managing these common, often hidden, feline diseases, says this article.
People generally favour the “seven-year rule”, which equates one cat year to 7 human years, however, it is not entirely accurate as cats age faster when they are young. This rate of ageing slows down after the first few years of life.
An hour for a dog feels much longer than an hour for a human because dogs perceive time more slowly due to their faster metabolism and heightened awareness of routines, so a 10-minute wait can feel like 70 minutes to them, and your hour-long absence feels like an eternity, though they don't grasp clock time but rather the intervals between events like meals, walks, and your return.
Dogs evolved from gray wolves, but scientists debate exactly where, when and how many times dogs were domesticated. Ancient DNA evidence suggests that domestication happened twice, in eastern and western Eurasia, before the groups eventually mixed. That blended population was the ancestor of all dogs living today.
Bears are carnivoran mammals of the family Ursidae (/ˈɜːrsɪdiː, -daɪ/). They are classified as caniforms, or doglike carnivorans.
In regions where their ranges overlap, tigers stand as the only big cats capable of regularly hunting and killing adult bears. These apex predators possess the size, strength, and hunting skills necessary to take down even fully grown brown bears and Asiatic black bears.
Carnivora evolved into two main branches:
Caniformia, which includes dogs and seals. Feliformia, which includes cats and hyenas.
Bears are the youngest of the carnivore families, having arisen from doglike ancestors during the Eocene Epoch 55 million to 38 million years ago. The earliest bears had the characteristics of both dogs and bears, with heavy-set features and blunter teeth than those of true dogs.
Karelian Bear Dogs will hunt a variety of animals. Its quick reflexes and fearless nature have made it very popular for hunting large game including brown bears, moose, and wild boar. It was the breed's ability to hunt bears that earned the breed its name.
Therefore, while bears are distinct from both dogs and cats, they are more closely related to dogs in the broader context of evolutionary relationships. So bears and dogs share a common ancestor, this connection is one from millions of years ago.
The Caninae are the canines, and include domestic dogs, wolves, coyotes, raccoon dogs, foxes, jackals and other species. Canids are found on all continents except Antarctica, having arrived independently or accompanied by human beings over extended periods of time.
To find out more, the team analyzed thousands of dog and wolf genomes in publicly available databases. They found that over 64 percent of modern breeds have wolf ancestry, with even tiny chihuahuas carrying around 0.2 percent.
The #1 smartest dog breed, consistently ranked by experts like Dr. Stanley Coren, is the Border Collie, known for its exceptional ability to learn commands quickly (sometimes in under five repetitions) and obey them consistently, excelling in problem-solving and demanding mental stimulation. Other top contenders for intelligence often include the Poodle, German Shepherd, Golden Retriever, and Shetland Sheepdog, recognized for their trainability and eagerness to please.
Canis familiaris are highly adaptable and probably would not go extinct globally even in the absence of humanity. There are populations of feral dogs all over the world which eke out a living through scavenging and predation, in fact in some areas they're considered an invasive pest and a conservation issue.
The 3-3-3 rule for dogs is a guideline for the adjustment period after adoption, outlining three phases: 3 Days (decompression, feeling overwhelmed/scared), 3 Weeks (starting to settle in, learning routine, personality emerges), and 3 Months (feeling secure, bonded, and truly at home). It helps new owners manage expectations and be patient as their rescue dog transitions, emphasizing calm energy, routine, and space in the early days to build trust.
Harvard psyhologists reveal that dogs dream of their humans
What you may not have realised however is, according to new research by Harvard psychologists, your dog is likely to be dreaming about you too – their human – the most important thing in their life.
Fortunately for us, dogs do not understand they are being put to sleep. They may behave differently at this time generally because they feed off the emotions of their closest humans, who are understandably destraught. Plus they also getting all of this extra attention so they probably wonder what is going on!
The 3:3:3 Rule: Help Your New Cat Adjust to Their Home The 3:3:3 rule explains some general expectations for the transition process and some tips on how to support your cat through each stage: 3 days for initial acclimatization, 3 weeks for settling in, and by 3 months, they should be comfortable and at ease in their ...
Cats are often thought of as being independent creatures who are happy in their own company. But your cat can get lonely. Interacting with the human they love helps to enrich their lives (and yours). If your cat sleeps with you this indicates that they enjoy your company and want to spend time with you.
The number one killer of cats depends on age and lifestyle, but cancer is the leading cause of death in older cats, while Feline Leukemia Virus (FeLV), accidents/trauma (especially for younger cats), and diseases like kidney/heart issues are major factors, with FeLV often cited as the top infectious killer. Causes range from diseases like FeLV, Feline Immunodeficiency Virus (FIV), and FIP, to organ system failures (kidney, heart), and external factors like poisons or trauma.
