Marked his territory

A person with long dark hair, wearing a white shirt and dark pants, sits on a low wall or ledge on a paved outdoor area. A black and white dog approaches from the right, walks toward the person, briefly stands on its hind legs to place its front paws on the person's lap, then turns and walks away down the paved surface. The scene is set outdoors on a light-colored paved surface with a metal railing visible on the left.
