Many dogs experience petting as a form of affection from humans, which makes these interactions not only pleasant, but even supportive of your dog's mental health. In fact, research shows that dog brains release the love hormone Oxytocin when they're petted and given attention from a human.

Although some dogs tolerate head pats, most instinctively feel uncomfortable when a hand reaches down from above their head.

In our hearts, we know the answer to “why do dogs like to be petted?” It feels good! But along comes science to confirm it. Research shows that when we interact positively, such as through cuddling and petting, both dogs and humans get a boost of oxytocin, the warm-and-fuzzy hormone.
