The chimp who thinks he's a puppy.

The chimpanzee was born at a Russian zoo and was taken home by one of the staff after it became clear he had not bonded with his mother. By chance, her 100lb bull mastiff had just given birth and the dog was soon treating the new addition as one of the family. Endearingly, the chimp soon seemed to think he was a puppy himself, bending double to eat from food bowls with his adoptive siblings.
