Cranky

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

Unlike Grundgetta'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.
