Biting

Anybody have some solutions? I haven't received a single comment or response from any forum users nor from the folks at SitStayFetch, which I thought was part of the package I purchased. Anyone?

My Lhasa is 9 yrs old. Although he was well socialized as a puppy (is an AKC confirmation champion) and obedience trained, he can still be aggressive. I was nervous every time a judge touched him. He went through handling classes at 7 mo old, and the instructor said he never knew what he was going to do. He even went through an agility course. He was voted least enthusiastic because he did things when HE wanted to do it. He has always remained very dominant, even after much behavior training and retraining. And yes, he IGNORES discipline. He does NOT like to be picked up, esp by strangers. As far as I know, he's never bit anyone for this. He Hates his crate, always has, and will fuss and attempt to bite you if you physically push him into it. And then he barks, fusses, scratches and tries to get out the whole time. He actually rocked himself out of the car one day onto the ground from inside his crate from pushing and jumping on it. He WILL nail you (bite) if you step on him or his tail. He fusses (grumbles) the whole time he gets a bath. He WILL nail you if you're grooming his feet (or anywhere) and he warns you to stop and you don't. Even us, his owners. Every groomer I know will tell you (and has told me) this is inherent of the breed. And I've not seen any books or information on the breed that says they're happy go lucky, easy going, well behaved, like-everybody dogs! Mine has issues with ankle biting friends as they LEAVE my house, not when they enter. And yes, he draws blood. Even with help from dog trainers, and the final use of an E collar, it is still not resolved. He knows when it's not on him. I now just have to put him away if company comes. He is very smart, and loyal, knows lots of tricks, and I love him, but his behavior is annoying. He is a terror at my windows, constantly lunging and barking at them when he sees anyone outside. Same thing in the car. Sometimes we think he's going to take out the glass. I can't answer the door because he does the same thing. I've tried teaching him to sit and stay, (which he knows very well) but as soon as that doorbell rings or someone knocks, he goes nuts and refuses to mind. I've tried distracting him with treats, but he ignores it. He didn't bait in the show ring either. Bark collars only stop the barking, not the lunging. He is not dog aggressive, doesn't bark at people outside my home, and walks on leash just fine. No pulling, etc. At 3 mo old, my vet told me I would have my hands full with him. My trainer saw him at 4 mo old, and said the same thing. And I have. My husband hates him. I neutered him at age 3 because I didn't want his temper passed on. I don't trust him with anyone. I feel for you. It's not all his fault though. The rest of the family isn't consistent with training, and as I've said, my husband has nothing to do with him. They crossed paths very early on and it's been like that every since (for years). Since the dog doesn't act submissive and wag his tail when he looks at him, he doesn't like him. This little guy could add a whole chapter to the dog training book! I'm here looking for help too...
