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.
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.
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.
The results of a new canine numerosity study suggests that a common neural mechanism has been deeply conserved across mammalian evolution.
The impact of animal-assisted interventions for both patients and health services could be substantial, but more rigorous research is needed.
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.
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.
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.
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.
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' doctors have warned after treating a middle aged man with severe lung inflammation that developed soon after he bought feather-filled bedding.
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.
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 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.
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.

New research shows that some breeds of dogs have hidden coat colors -- and in some cases, other traits -- that have been lurking all along.
Estrogen's role in canine mammary cancer is more complex than previously understood, according to new research. The nuanced findings may help explain why dogs spayed at a young age are more likely to develop more aggressive cancers, the team says.
Detection dogs trained to sniff out the scat of an endangered lizard in California's San Joaquin Valley, combined with genetic species identification, could represent a new noninvasive sampling technique for lizard conservation worldwide.
Laryngeal paralysis is a serious and sometimes deadly disease in some dog breeds that prevents proper opening of the larynx for breathing. Specialists in canine head and neck surgery and geneticists have identify a mutation responsible for laryngeal paralysis in Miniature Bull Terriers, enabling the development of a genetic test for the disease.
Pulmonary hypertension is a type of high blood pressure that affects the lungs of both animals and people. When tiny vessels in the lungs become narrowed or blocked, it becomes harder for blood to flow through and can cause the heart to weaken or fail.
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 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.
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.
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 (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.
