A new analysis dives into the use of service dogs by U.S. veterans who have posttraumatic stress disorder (PTSD), illuminating factors and mechanisms that may underlie the mental health effects of these relationships.
New research has revealed an association between the feeding of raw meat to pet dogs and the presence of bacteria resistant to critically important antibiotics.
Researchers have developed a protocol for using robotic pets with older adults with dementia. The protocol uses a low-cost robotic pet, establishes ideal session lengths, and identifies common participant responses to the 'pets' to aid in future research.
Researchers have provided the first documentation that dogs' sense of smell is integrated with their vision and other unique parts of the brain, shedding new light on how dogs experience and navigate the world.
In a new finding that goes against current conservation paradigms, re-introducing wolves and other predators to our landscapes does not miraculously reduce deer populations, restore degraded ecosystems or significantly threaten livestock, according to a new study.
Sniffing or licking other dogs' genitalia -- the common site of Canine Transmissible Venereal Tumour -- can spread this unusual cancer to the nose and mouth.
An international group of geneticists and archaeologists have found that the ancestry of dogs can be traced to at least two populations of ancient wolves. The work moves us a step closer to uncovering the mystery of where dogs underwent domestication, one of the biggest unanswered questions about human prehistory.
In a new study, researchers have sampled the fecal microbiomes across diverse geographical populations of dogs to better understand what they look like around the world.
Over a 30-year period, African wild dogs shifted their average birthing dates later by 22 days, an adaptation that allowed them to match the birth of new litters with the coolest temperatures in early winter. But as a result of this significant shift, fewer pups survived their most vulnerable period because temperatures during their critical post-birth 'denning period' increased over the same time period, threatening the population of this already endangered species. It is the first study to show that large mammalian carnivores are making major changes to their life history in response to a changing climate.
Thirteen genetic variants associated with disease in cats are present in more pedigreed breeds than previously thought, according to the largest ever DNA-based study of domestic cats. However, these variants are declining in frequency in breeds that are regularly screened for the genetic markers.
Dog-assisted interventions can lead to significantly lower stress in children both with and without special needs, according to a new study using salivary cortisol levels.
English Bulldogs must be bred with more moderate physical features, experts say, as a new study reports that the breed is significantly less healthy than other dog breeds. English Bulldogs are at increased risk of breathing, eye, and skin conditions due to their extreme physical features, including shortened muzzles, folded skin, and a squat body, reports a recent article.

A fossilized lower jaw has led an international team of palaeontologists to discover a new species of predator that once lived in Europe. These large predators belong to a group of carnivores colloquially known as 'bear dogs'. They could weigh around 320 kilograms, appeared 36 million years ago before becoming extinct around 7.5 million years ago.
An inhaled immunotherapy successfully treated cancer in some companion dogs as part of a clinical trial conducted by oncology and veterinary researchers. Results show potential for fighting cancer in humans as well.
Intestinal flora plays an important role in health -- including mental health. Researchers have shown that probiotics can support the effect of antidepressants and help to alleviate depression.
Young children who grow up with a dog or in a large family may have some protection later in life from a common inflammatory bowel disease known as Crohn's disease, according to a new study.
Veterinarians and researchers have developed a technique to predict leptospirosis in dogs through artificial intelligence. Leptospirosis is a life-threatening bacterial disease dogs can get from drinking contaminated water.
A recent study confirmed that scent detection dogs can be taught to identify individuals with a coronavirus infection from skin swabs. In the experimental set-up at Finland's Helsinki-Vantaa International Airport, the accuracy of the dogs in identifying the samples was 92 percent.
Researchers have found that a suite of complimentary tests can quantify changes in dogs suspected of suffering from cognitive decline. The approach could not only aid owners in managing their elderly canine's care, but could also serve as a model for evaluating cognitive decline progression in -- and treatments for -- humans with Alzheimer's disease.
Modern day Patagonian sheepdogs are the closest living relative to now-extinct varieties of herding dogs of Victorian era Britain, according to a new study.
Despite the good care, a shelter can be a stressful environment for dogs. Researchers investigated if the amount of the hormone cortisol in hair indicates the levels of stress that dogs experience before, during and after their stay in the shelter.
A survey of veterinarians in the U.S. and Canada highlights mounting cases of cannabis poisoning among pets and sheds new light on symptoms, treatments, and outcomes.
