Max is a mutt that lives in the same complex as Dook. On occasion, his owner will drop Max off at Dook's owner's place. Max's favorite pastimes are barking while hiding behind something (or someone), chewing on stuffed animal ears, giving Dook (and now Chessie) lots of kisses, and chasing down that elusive red dot that shows up from time to time.
Raoul is a wolf that has known Chessie since she was a kit. He's pretty patient with Chessie's antics, though that may come from being a little older than her.
