Sometimes Sammy will only make 1 mistake during the day. The next day he might make 6 mistakes. Now that its cold he doesn't want to go potty outside and when he comes in he pees!! It makes me soooo ANGRY. But then his cuteness makes up for it..... anyways, I take him out every hour to an hour and a half. He holds it for the intire night (most nights) and doesn't wake me up at all. But during the day he's not that great. He has learned that he can go in his kennel and pee on his pad. sometimes he does it, and other times he doesn't. It's like he plans in the morning "I am gonna pee all over the house today" and the next day "I feel like being an angel"
