I'd do what Laura suggested. Find a behaviorist who will work with your dogs AND you. Sometimes, dogs will respond 100% to the trainer who trained them but the moment their owner asks them to sit, they refuse to. It's likely, they respect the trainer, not you. It also sounds like they think they're the top dogs. One of my dogs was extremely dominant back in September. With some consistant training, he accepted the position of the lowest ranking dog in the pack and things have gotten much better from there. The only command he would do back then was sit. I was positive he knew down but refused to. Why? Because he didn't respect me as the alpha. He growled and bit me when I asked him to down (as down is a submissive position). After he learned that I was the alpha, things got 110% better.

So, I'd look for a behaviorist who has had experience with dogs like yours. Make sure they will work with you and your dogs as they need to know that you and your husband are the top dogs, not just the trainer.
