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.
