Cranky

Cranky is Oscar the Grouch's pet Rottendoodle -- a grouchy breed of dogs. Oscar adopts Cranky in episode 4127.

Unlike Grungetta's Rottendoodle, Itchy, Oscar's dog is helpful, polite and loving. Thinking that Cranky is sick, Oscar brings her to Gina for veterinary advice. Gina helps Oscar to accept his dog for who she is -- a sweet, playful and annoying pet.
