Hazel is a timid, soft-spoken red squirrel that lives "across the pond". When nervous, she tries to hide herself behind her long, poofy tail. It's assumed that Chessie and Hazel are cousins, but the exact lineage is unclear.
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.
