shit rat

A miserable little dog, usually a terrier. The owner thinks that the sun shines out of their shit rat's arse. Given the opportunity, a shit rat will piss all over your house, and/or yap incessantly at nothing at all.

My girlfriend's Scotty is a shit rat. She pisses all over the floor right after going for a walk.
