Our dog, Mingus, plays a game we call "Get the kitty!", which generally consists of Mingus snapping/pawing at our cat, Chuck, until Chuck comes after him. From there it usually degenerates to Chuck lying on his back swinging an occasional paw at the dog if he comes close.
This dog plays "Get the monkey!" and the capuchin seems to play by Chuck's rules. The monkey even looks a little like Chaz.
Curious...
