Caretaking: promotes sense of responsibility and empathy, increases physical activity (eg, walking, grooming), allows for learning about animals. Companionship: promotes self-esteem, relieves stress, provides emotional support (pet dog can act as a confidante). Social interaction: catalyzes social interactions, stimulates verbal and nonverbal communication, and develops relationships.
