2 year old lab is peeing on the carpet
I recently moved in with my girlfriend and I have a Rottie mix and she has a yellow lab. Both dogs are neutered and have spent ample time together in the past. The problem we are having is her two year old Yellow Lab is now from time to time peeing in the house. One night we were playing and he just stopped and started peeing, this morning when we got up there were two spots in the living room. I don't think it is a dominance thing; it just seems that he has decided not to be house broken anymore. Any suggestions?
