Factory Dog
A factory dog is a stupid, clumsy dog that comes from a messed-up lab where they tried to make perfect dogs and failed. They can't aim worth a damn and always miss what they're trying to hit.
My dog tried to catch a frisbee and missed it so bad he hit the neighbor's cat.
He tried to bite the mailman and just got stuck in the mailbox.
He chased a squirrel and ended up stuck in a tree with no way down.
