I have two four and a half year old male chihuahuas who are brothers and they have been neutered. I have to keep them in a separate room with a gate up since they ruined my couches. I use potty pads and sometimes they use them and sometimes they do not. At night I put them in their crates and in the a.m. they do bark and I bring them straight out to the backyard and they do do their duty. Howevever, this morning I took the little one in on a leash and he picked up his leg and urinated on my new couch before I could put him in the room. In the room, when they are not in their crates they pee all over. I tried to find a new home for them, but cannot find someone who wants to deal with this. What can I do?
