Buddy has taken to peeing in the house. It is generally in one of two areas of the house, the base of the stairs in the hallway and on the rug in front of the doggy door. He has even done it up stairs in the living room and also the kitchen, though not as often. He has access to the outside all day. There have been no changes in the house I can think of that would be upsetting. And aside from taking thyroid medication he is a very healthy 8 year old boy. Also can anyone recommend a good cleaner to get rid of the pee smell? The smell was overwhelming as I walked in the door tonight.
