Dog Pees While Sitting Down and in His Crate?

I adopted a 1.9 year old Siberian Husky. They told me he was house broken, but he keeps soiling in the house. I keep him on a schedule, control his food intake, and take him for long walks to ease his anxiety. He will still come in and pee, the most alarming thing is that he pees while sitting and pees in the crate. I took him to the vet, but the vet doesn't think he has a UTI. Anyhow I am waiting for the results. If it's not a UTI; what's wrong with him? And how do I correct him? I have tried everything in the book.
