Sometimes if they have that problem, a dental cleaning could help, ask your vet though. I crate trained my dogs, and if they peed, they would get corrected , if they got a light tap with the fly swatter , shamed and got to where sometimes one would pee in the garage, so put a fly swatter on the cleaned spot........no problems now. We have doggie doors. so they can go out whenever. Hope your little ones do better, Love really helps!
