We have a somewhat similar problem with the new cat we brought home....she likes to growl and hisses excessively at the other three cats. It IS a dominance issue at our house, but I don't want the other three to be terrified all the time, just like you don't want your sweet lab to be.

My suggestion....get a spray bottle. I know it sounds really mean, but when Bandit feels a cold stream of water on his skin while attacking your dog, he'll get the idea that isn't not a good thing to do.

I hope that can help you. Its hard when the furkids don't get along.
