My sister has 2 yorkshire terriers. The one is very good, and the other one is dumb and uses the whole house to crap/piss. She's tried everything, but it doesn't work. However, she says the little things can't go more than 30-60 minutes without a trip outside. (Personally, if that's all the longer they can go, they'd be sleeping with the fishes) So I dunno, there may be no hope for you. Our little dogs here (pug and korgie) both pee in their crates and on the floors from time to time. Luckily, we have wood floors, but if our mastiff's bed is laying out, they will sometimes pee on it. So it's washable. Stupid little dogs...
