I have a 5 year old Male Yorkie and an almost 4 month old Yorkie. Well Dallas the older one has been completely house broken and in the last two weeks is now peeing and pooping in the house again , sometimes it's around the little one's pen or crate but not always. I understand being a male he is marking his territory but now he doesn't it anywhere and I dont know what to do to stop him. I have fussed at him and put him in his crate and he knows better b/c once he does it he runs into his crate with his head down. Please give me some advice house breaking one is bad enough!
