Peanut: A rambunctious puppy with overly big ears. Overall, nothing but trouble.
Butter: A plump, persnickety cat, who lives with Crackers. In other words, above it all — especially canines.
Crackers: A goofy rescue dog, whose peaceful home life, along with Butter’s, is disrupted when Peanut arrives on the scene. Definitely not a fan of drama.
