We,have a Shihtzu, a rescued 2 year old. Second owner claims found in the sreet, given to her mom,who died when dog was two. Kids & wife love dog, when he sees me home from work, he comes running tail wagging. If I touch him he pees. If I am sitting on the couch dog will lay at my,feet until I motion him to jump on my lap. He then pees while I pet him. He is not afraid of me, never been hit but if this coninues I have to get him out of the house .Dog has doggy door. I can't live with this. Please help.
