Hello all, i just joined this site in hopes of finding others like myself. I am the proud mama of a Brother and sister 7 month old yorkies. The Boy, Oso is 5.5 pounds and my lil one is SusieQ at 3 pounds. Guess the parents were a little on the small size. I think Oso is about 75% house trained but SusieQ seems to not have a clue. I have setup where their crate (no door on it) is like a little room for them. Their food and water dishes are next to it and then I corralled around all that which is about 3-4 feet and it has full access to the doggie door. In the night I can hear them going in and out of the doggie door. When I take them out of the caged area SusieQ will squat and pee or poo like nothing. I have seen her go out the doggie door quite a few times so what's up with that?
