  • Genes play a role in dog breed differences in behavior
    on October 8, 2019 at 8:58 pm

    Border collies are highly trainable, greyhounds love to chase, and German shepherds make good guard dogs. While the environment plays a role, traits like these are highly heritable, according to a study of 101 dog breeds. The work identifies 131 genetic variants associated with breed differences in behavior.

  • Dog ownership associated with longer life, especially among heart attack and stroke survivors
    on October 8, 2019 at 12:31 pm

    Dog ownership was associated with a 33% lower risk of early death for heart attack survivors living alone and 27% reduced risk of early death for stroke survivors living alone, compared to people who did not own a dog. Dog ownership was associated with a 24% reduced risk of all-cause mortality and a 31% lower risk of death by heart attack or stroke compared to non-owners.

  • Dog owners often inaccurately measure out kibble
    on October 7, 2019 at 4:32 pm

    New research finds dog owners are often inaccurate when measuring out kibble using a scoop, putting the dogs at risk of under-nourishment or weight gain.

  • Identifying a gene for canine night blindness
    on October 3, 2019 at 9:37 pm

    Researchers have identified the gene mutation responsible for a form of night blindness in dogs. Strategies to treat this condition, which affects a layer of neurons just below the primary photoreceptor cells, could also inform treatment of other diseases that rely on targeting this cell type.

  • Lop-eared rabbits more likely to have tooth/ear problems than erect eared cousins
    on October 1, 2019 at 10:49 pm

    Lop (floppy) eared rabbits are more likely than erect ('up') eared breeds to have potentially painful ear and dental problems that may ultimately affect their ability to hear and eat properly, finds a small observational study.

  • Immune response against Toxocara roundworms helps explain disease
    on September 26, 2019 at 6:50 pm

    Neurotoxocarosis (NT) occurs in humans when larvae of the Toxocara roundworm migrate into the central nervous system. That infection is accompanied by a complex molecular signaling cascade, including changes to anti-inflammatory lipid molecules, researchers now report.

  • Dog rabies vaccination programs affect human exposure, prophylaxis use
    on September 26, 2019 at 6:17 pm

    The World Health Organization has made it a goal to eliminate human rabies deaths due to dog bites by the year 2030. An increase in dog rabies vaccination rates decreases dog rabies cases, human exposure, and human deaths, researchers now report.

  • What wolves' broken teeth reveal about their lives
    on September 24, 2019 at 6:31 pm

    An evolutionary biologist has spent more than three decades studying the skulls of many species of large carnivores -- including wolves, lions and tigers -- that lived from 50,000 years ago to the present. She reports today the answer to a puzzling question.

  • The problem with promoting 'responsible dog ownership'
    on September 24, 2019 at 4:50 pm

    Dog welfare campaigns that tell people to be 'responsible owners' don't help to promote behaviour change, a new report suggests. Dog owners interviewed for a study all considered themselves to be responsible owners, despite there being great variation in key aspects of their dog-owning behavior.

  • Antibody testing reveals dogs can suffer from same autoimmune encephalitis as humans
    on September 23, 2019 at 6:07 pm

    Researchers have found that dogs can suffer from the same type of autoimmune encephalitis that people do. The finding could lead to better screening methods for diagnosis and possibly more effective treatments for canine encephalitis.

  • Cats are securely bonded to their people, too
    on September 23, 2019 at 3:12 pm

    Cats have a reputation for being aloof and independent. But a study of the way domestic cats respond to their caregivers suggests that their socio-cognitive abilities and the depth of their human attachments have been underestimated. The findings show that, much like children and dogs, pet cats form secure and insecure bonds with their human caretakers.

  • Overweight Danes are more likely to have overweight dogs
    on September 19, 2019 at 1:52 pm

    A new study reports that the prevalence of overweight dogs is markedly larger among overweight owners than among normal weight owners. Part of the explanation lies in whether treats are used as training tools or ''hygge-snacks''.

  • The diet-microbiome connection in inflammatory bowel disease
    on September 9, 2019 at 9:07 pm

    A change in diet is a go-to strategy for treating inflammatory bowel diseases like Crohn's. In dogs with a similar illness, researchers tracked specific changes in the microbiome as the pets went into remission. The team's findings, which mirror what is seen in children with Crohn's, could inform the design of improved therapeutic diets.

  • Hidden danger from pet dogs in Africa
    on September 9, 2019 at 2:46 pm

    Researchers have detected a potentially human-infective microbe in pet dogs in Nigeria.

  • Feeding pets raw food is not considered by pet owners as a significant source of infections
    on September 6, 2019 at 2:41 pm

    An extensive international survey indicates that pet owners do not consider raw food to considerably increase infection risk in their household. In the survey, targeted at pet owners, raw food was reliably determined to be a contaminant only in three households.

  • Furry friends ease depression, loneliness after spousal loss
    on September 5, 2019 at 2:25 pm

    Researchers have found the companionship of a pet after the loss of a spouse can help reduce feelings of depression and loneliness in older adults.

  • How humans have shaped dogs' brains
    on September 2, 2019 at 5:53 pm

    Dog brain structure varies across breeds and is correlated with specific behaviors, according to new research. These findings show how, by selectively breeding for certain behaviors, humans have shaped the brains of their best friends.

  • Yet another way dogs help the military: aeromedical patient evacuations
    on August 22, 2019 at 6:19 pm

    Animal-assisted therapy has many benefits in health care. Yet, its biological and psychosocial effects in the military are unknown, especially for injured, airlifted patients. Researchers teamed up with a non-profit animal organization that trains therapy dogs to see if an animal-assisted intervention could reduce stress in this setting. Results showed that levels of the stress biomarkers cortisol, alpha-amylase, and immunoglobulin A, significantly decreased after a 20-minute intervention with the dogs, regardless of post-traumatic stress symptom severity.

  • Hush, baby -- the dog is whimpering!
    on August 21, 2019 at 4:08 pm

    We are all familiar with the sounds of a cat or dog vying for human attention, and for pet-owners, these sounds are particularly evocative. Dog sounds are especially sad to both cat and dog owners, who actually rate a whimpering dog as sounding as sad as a crying baby.

  • Treating dogs with human breast cancer drug
    on August 20, 2019 at 7:36 pm

    Like many women who develop a particular type of breast cancer, the same gene -- HER2 -- also appears to be the cause of lung cancer in many dogs. Researchers found that neratinib -- a drug that has successfully been used to battle human breast cancer -- might also work for many of the nearly 40,000 dogs in the US that annually develop the most common type of canine lung cancer, known as CPAC.
