Best friend

A man in a light-colored shirt and dark pants stands in a room, holding a small object, then turns and walks toward a table before sitting down. As he sits, a dog runs into the frame from the left, jumps onto his lap, and causes him to fall backward onto the floor. The man lands on his back with the dog on top of him, and the dog remains on his chest as he lies on the floor. The setting is a dimly lit room with a bookshelf, a chair, and a table.
