* Dog domestication may have increased harmful genetic changes, biologists report

The domestication of dogs may have inadvertently caused harmful  genetic changes, a UCLA-led study suggests. Domesticating dogs from gray wolves more than 15,000 years ago involved artificial selection and inbreeding, but the effects of these processes on dog genomes have been little-studied. UCLA researchers analyzed the complete genome sequences of 19 wolves; 25 wild dogs […]

How dogs see your emotions: Dogs view facial expressions differently

A recent study from the University of Helsinki shows that the social gazing behavior of domestic dogs resembles that of humans: dogs view facial expressions systematically, preferring eyes. In addition, the facial expression alters their viewing behavior, especially in the face of threat. The study was recently published in the science journal PLOS ONE. The […]

Precise method underlies sloppy madness of dog slurping

Stories about lap dogs are everywhere, but researchers at the Virginia Tech College of Engineering can tell the story of dog lapping. Using photography and laboratory simulations, researchers studied how dogs raise fluids into their mouths to drink. They discovered that sloppy-looking actions at the dog bowl are in fact high-speed, precisely timed movements that […]

Dogs give friends food

Compared to the rest of the animal kingdom, the human capacity for cooperation is something quite special. Cooperating with one another requires a certain amount of prosocial behaviour. This means helping others without any direct personal benefit. Prosociality has already been demonstrated in animals that are very closely related with humans, i.e. primates. In other […]

* Puppy bred to have muscular dystrophy saved by surprise mutation

Ringo, a golden retriever born in 2003 in a Brazilian kennel, was never expected to live long. Researchers bred him and his littermates to inherit a gene mutation that causes severe muscular dystrophy. They hoped that the puppies would provide insight into Duchenne muscular dystrophy (DMD), an untreatable and ultimately fatal human disease caused by […]
