My mother is going to get rid of her dog because it keeps pisin in the house. A little info on him - he gets looked in the passage part of the house all day which is about the size of a kitchen and gets taken out the back for a piss and walked at night. My brother has adhd and always winds the dog up the other side of the babies gate between the passage and the dinning room and my mother's childish b/f also winds the dog up and tells him off for doing nothing so the dog aint exactly learning right from wrong. Is there anyway or tips to stoping the dog from pissin in the house. He's 3 years old, is it to late.
