Emotional contagion has been studied extensively in birds, primates and dogs, among other animals. It is generally more pronounced between individuals who know each other than between strangers. Emotional contagion occur between dogs and people. There is evidence that...

Dogs Helped Humans Hunt Mammoths
New evidence from archaeological sites
Archaeological sites with hundreds of dead mammoths posed a puzzle to scientists: How could humans kill so many of these massive animals with the weapons available at the time? The answer is that one of the “weapons” used was not made of stone like the other tools of the time, but was made of flesh and blood. It was the domestic dog. According to new research by Pat Shipman at Penn State...

Dogs' Responses to Familiar Human Scents
Their brains reveal a positive response
You may not feel happy when you smell your husband’s underarm when he has not showered or used deodorant for 24 hours, but your dog probably does. So concluded scientists who conducted an fMRI study to investigate the response of dogs’ brains to both familiar and unfamiliar canine and human odors. Since the canine sense of smell is so well-developed, studies that investigate it are especially...

Dog and Human Voice-Sensitive Brain Regions
The similarities are considerable
If you’ve always thought that you and your dogs understand one another’s emotions, you increasingly have scientific evidence supporting your views. The use of MRIs allowed researchers to demonstrate that the brains of both dogs and people have a similar response to human voices, crying and laughter, among many other sounds. Researchers conclude that the brains of both dogs and people have similar...

Tibetan Mastiffs Adapted to High Altitude
Dog flexibility strikes again
If you’re not amazed by the diversity of dog body type and the huge number of habitats in which they can live, then you’re in the minority. Scientists, dog lovers and scientists who are dog lovers consider the domestic dog a species of considerable interest for the great number of forms that have evolved over a relatively short time. Some of the variation is obvious because it involves shape,...

Is Your Dog a Southpaw?
Links between canine lateralization, behavior and emotion
Dalmation Jumping by Amanda Jones
A few years ago, dog trainers and behaviorists renewed their love affair with tail-wagging, constantly checking to see whether dogs were wagging their tails higher to the right or to the left. Our awkward attempts at positioning ourselves to observe this behavior were surely entertaining to others. Why were we so eager for the information conveyed by these asymmetrical tail wags? Because they...

Puppy Dog Eyes Influence Humans
Infantile features have power
Those big puppy dog eyes may be powerful in addition to just being cute. According to a recent study, they may actually affect human choice about which dogs to adopt. The researchers who conducted the study “Paedomorphic Facial Expressions Give Dogs a Selective Advantage” found that dogs whose facial expressions made them look more puppyish were adopted more quickly from shelters than dogs who...
