A study conducted by veterinarian Lisa Horn from the University of Vienna found that dogs and cats view their human owners as their parents. The study observed 22 puppies divided into three groups, with those in the group with their parents being the most cheerful and playful. Dogs feel more motivated and secure when they are close to their human parents, according to the study. When separated from their parents, they become insecure, fearful, and disinterested. The same is true for children who feel safer and more capable when accompanied by their parents. Pets see their human owners as their world and all they have.
