Any dog that is small enough to be drop kicked like you're punting an american football.
Dogs that are this small aren't really even dogs at all. They're annoying and piss and crap in the house. Their owners call this common occurrence an accident and feel the need to cater to the animal's every perceived need.
Dude, why are you walking funny and paying for all of your girlfriend's stuff.
Oh, she has a puntable dog so I can't sleep comfortably in the bed because the puntable dog takes up the whole thing and she had to buy it the most expensive food, sweaters and haircuts for it as well. I think we're even spending more on it's kennel then for our vacation when we're away.
