I could never own a hairless dog. It'd freeze up down here before my muscovies would.
Florida is probably the best place for hairless dogs. My dog suffers in the summer. He goes out to pee - quickly - in the shade - and then wants right back in. When he was a puppy and was potty training, I'd take him out and he'd look at me like "really, I HAVE to be out here to pee? Are you kidding me, lady?"
