A small, tricolor Cavalier King Charles Spaniel dog is lying on its back on a dark blue mattress, with its belly exposed. The dog is mostly white on the belly, with black and tan markings on its head and back. Its fur is long and wavy. A hand reaches in and gently rubs the dog's belly. A small, black and white puppy with a blue collar is lying on the dog's belly, near the dog's teats. The dog appears relaxed and may be sleeping. A cardboard box is partially visible in the upper left corner. The scene appears to be indoors, possibly on a bed.
