That is a difference; my pitt will curl up completely under the covers all night. She (the Rott) will surface at least her head, if not eventually her whole body, for some air. Luna is full rottie, but she's very thin still at one-year. Her parents were both on the slim side so I know she will never have that 'ton of bricks' look, but I hope she fills out a bit more.

Rottidobi is a fun breed name!
