  • Bartonella bacteria found in hemangiosarcoma tumors from dogs
    on January 16, 2020 at 5:18 pm

    Researchers have found a very high prevalence of Bartonella bacteria in tumors and tissues - but not blood samples - taken from dogs with hemangiosarcoma, a cancer of the blood vessels.

  • Scientists unexpectedly witness wolf puppies play fetch
    on January 16, 2020 at 5:18 pm

    When it comes to playing a game of fetch, many dogs are naturals. But now, researchers report that the remarkable ability to interpret human social communicative cues that enables a dog to go for a ball and then bring it back also exists in wolves.

  • Newly discovered genetic element adjusts coat color in dogs
    on January 15, 2020 at 2:34 pm

    Why are Irish Setters so red while other breeds can come in different hues? Geneticists now have an answer for why some dogs have more intense coat colors than others.

  • Preventing adverse drug reactions in dogs
    on January 13, 2020 at 6:53 pm

    If not identified before surgery, a rare genetic mutation could result in your dog being exposed to dangerously high levels of anesthetic agents.

  • Jaguars could prevent a not-so-great American biotic exchange
    on January 6, 2020 at 7:16 pm

    In eastern Panama, canid species from North and South America are occurring together for the first time. Urban and agricultural development and deforestation along the Mesoamerican Biological Corridor might be generating a new passageway for these invasive species adapted to human disturbance.

  • Dogs and wolves are both good at cooperating
    on January 6, 2020 at 5:34 pm

    A team of researchers have found that dogs and wolves are equally good at cooperating with partners to obtain a reward. When tested in same-species pairs, dogs and wolves proved equally successful and efficient at solving a given problem. This finding suggests that basic cooperation abilities were present in a common ancestor of dogs and wolves, and have not been lost in the domestication process.

  • Early-life exposure to dogs may lessen risk of developing schizophrenia
    on December 18, 2019 at 8:34 pm

    Ever since humans domesticated the dog, the faithful, obedient and protective animal has provided its owner with companionship and emotional well-being. Now, a study suggests that being around 'man's best friend' from an early age may have a health benefit as well -- lessening the chance of developing schizophrenia as an adult.

  • Dogs process numerical quantities in similar brain region as humans
    on December 18, 2019 at 8:33 pm

    The results of a new canine numerosity study suggests that a common neural mechanism has been deeply conserved across mammalian evolution.

  • Animal-assisted interventions positive for people's health
    on December 18, 2019 at 2:02 pm

    The impact of animal-assisted interventions for both patients and health services could be substantial, but more rigorous research is needed.

  • Dogs promote page turning for young readers
    on December 2, 2019 at 3:20 pm

    Reading in the presence of a pooch may be the page-turning motivation young children need, suggests a researcher. A new study examines the behavior of 17 children from Grades 1 to 3 while reading with and without a dog.

  • Unique sled dogs helped the inuit thrive in the North American Arctic
    on November 27, 2019 at 9:14 pm

    The legacy of these Inuit dogs survives today in Arctic sled dogs, making them one of the last remaining descendant populations of indigenous, pre-European dog lineages in the Americas.

  • Dinosaur skull turns paleontology assumptions on their head
    on November 25, 2019 at 10:34 pm

    A team of researchers has unearthed a well-preserved Styracosaurus skull -- and its facial imperfections have implications for how paleontologists identify new species of dinosaurs. Nicknamed Hannah, the dinosaur was a Styracosaurus -- a horned dinosaur over five meters in length with a fan of long horns. Paleontologists have learned much from those horns -- because they aren't symmetrical.

  • Simple model explains why different four-legged animals adopt similar gaits
    on November 21, 2019 at 7:14 pm

    Most mammals walk at slow speeds and run or trot at intermediate speeds because these movement strategies are energetically optimal, according to a new study.

  • Dog and sheep bones help injured pigeons fly again
    on November 20, 2019 at 5:11 pm

    Sheep and dog bones can be whittled into orthopedic pins that stabilize pigeons' fractured wings, helping the fractures to heal properly without follow-up surgery. Researchers describe the treatment, which is cheaper and more efficient than using metal pins for pigeon rehabilitative surgeries.

  • Watch out for 'feather duvet lung' caution doctors
    on November 19, 2019 at 12:08 am

    Watch out for 'feather duvet lung' doctors have warned after treating a middle aged man with severe lung inflammation that developed soon after he bought feather-filled bedding.

  • Humans' ability to read dogs' facial expressions is learned, not innate
    on November 11, 2019 at 3:50 pm

    Researchers assessed how experience with dogs affects humans' ability to recognize dog emotions. Participants who grew up in a cultural context with a dog-friendly attitude were more proficient at recognizing dog emotions. This suggests that the ability to recognize dogs' expressions is learned through age and experience and is not an evolutionary adaptation.

  • AI could help diagnose dogs suffering from chronic pain and Chiari-like malformation
    on November 7, 2019 at 4:29 pm

    A new artificial intelligence (AI) technique could eventually help veterinarians quickly identify Cavalier King Charles Spaniel (CKCS) dogs with a chronic disease that causes crippling pain. The same technique identified unique biomarkers which inspired further research into the facial changes in dogs affected by Chiari-like malformation (CM).

  • Liver-chip identifies drug toxicities in human, rat, and dog models
    on November 6, 2019 at 7:48 pm

    Liver toxicity is a big problem in the drug, food, and consumer products industries, especially because results in animal models fail to predict how chemicals will affect humans. A new Liver-Chip successfully predicts how different drugs impact rat, dog, and human models, and could help get the most effective drugs to patients faster.

  • New findings on gut microbiome's interactions with GI diseases
    on November 6, 2019 at 5:41 pm

    A study offers new insight on how the gut bacteria of dogs interact with a healthy vs. unhealthy GI tract, which could contribute to the development of new therapies for GI diseases in both dogs and humans.

  • Your dog might be hiding its true colors
    on November 5, 2019 at 7:09 pm

    New research shows that some breeds of dogs have hidden coat colors -- and in some cases, other traits -- that have been lurking all along.
