Our 10 month old Cavalier keeps pooping on the carpet, he only does it down stairs in the basement, he's pretty much house broken, but he does this a couple times a week. We take him out side often, so it's not like he just can't hold it anymore. When he does it we tell him "no" and he knows he's done something wrong, but it doesn't seem to set in. My wife and I have just about had enough, don't know how much more of this we can take. Also, our house smells like pee in some areas, but I haven't found any wet spots on the carpets. Any advise?
