Dogs and human love each other so much.
We all know that.
But why is that the case?
A short answer is that on an emotional plane, families do not see the dog as alien. According to John Archer of the University of Central Lancashire, who has conducted a detailed study of dog-human relations from an evolutionary perspective, about 40% of owners identify their dog as a family member reflecting social compatibility between our two species.
Dogs are extraordinarily attentive and have an uncanny ability to predict what their owners will do, whether getting the dog a meal or preparing to go on a walk. Experiments show that dogs and wolves can be astute readers of human body language using the direction of our gaze to locate hidden food.
Dogs also seem attuned to the emotional state of their masters and express contrition when the owner is annoyed, for example. Otherwise, the capacity to express affection – unconditionally – makes the dog a valued “family member.”
