My Shih-Tzu, Snickers, will be 3 in November. My boyfriend and I got him when he was only 8 weeks. He is potty-trained (we used wee-wee pads as we do not like crates) and we use a harness to walk him (our vet told us to because he chokes with a collar). When we take him out, he will urinate in a lot of places and also is very picky where he will poo (it usually takes him about a 30 min walk). That was the first of our problems and now when we leave the house we come back to various spots where he has urinated (tonight it was 7 BIG spots) we walk him a few times a day and right before we leave but still come back to messes, even if we are gone for only an hour or so. We will point at the spot and say no and he knows he's done wrong as he will put his head down and not go near the spot but he still continues to do it. He also tends to do it in the same places, no matter what we use to clean it up. My boyfriend and I are at our wits end! Please help us find a solution! PS - he is also not neutered and has only been trained to go outside, sit, give paw, and only by us (not a pro) could this also be a cause?
