A very small breed of dog that is a cross between a terrier and a chihuahua. Typical daily activities for a terrihuahua consists of pissing on carpets, chewing pillows, molding, candles, ornaments, and cleaning the litter box.
Dude, what is your dog doing?

Dont worry, terrihuahua's are known for catching the shit out of the the cat's ass while its pooping.
