get the dog into the bathtub 

You're screwing a girl in the ass. You try to get your nuts up in there as well. It's about as tough as trying to get the dog into the bathtub.

Dog in a Bathtub 

This is the proper name for when you attempt to insert your nuts into a girl's ass. It is so named this because it can be just as hard as keeping a dog in the tub while giving it a bath.
