Rat Dog 

Any animal of the Canine species that fits into a standard sized microwave.

Yapping, whining, biting ankles, and fitting into small purses are common amongst these animals.

KellEy: Check out my new puppy! She's a Chihuahua Yorkie mix.

Hailey: It's cute now, but just wait until it becomes a full-sized Rat Dog...
