The psychology professors and neuropsychological scientist claimed in an article available in Psychology Today that majority of the dogs are stressed due to hugs.

The research examined those 250 Internet photographs of individuals hugging their dogs have indications of worry in the dog, including turning their head away, viewing the whites of the eyes and slicked back ears.

Coren’s fact states that about 82 percent of dogs in the pictures indicated the signs of stress. At around 8 percent of dogs looked very happy with the hug and the last 10 percent seemed neutral or showed an uncertain reaction in the movement

According to Coren, “Dogs are technically cursorial animals, which are a term that indicates that they are designed for swift running. That implies that in times of stress or threat the first line of defense that a dog uses is not his teeth, but rather his ability to run away. Behaviorists believe that depriving a dog of that course of action by immobilizing him with a hug can increase his stress level and, if the dog’s anxiety becomes significantly intense, he may bite.”
