Barking, growling, or whining is an additional form of communication, not the primary one. They tell each other almost everything through body language first, then by scent. When two strange dogs meet, there is very little sound. Because we depend so much on speech, we tend to think that dogs communicate that way too, when in fact, they don't. Dogs do not understand English (or any other language). Hearing dogs learn the meaning of words through repetition. It doesn't require any more time, effort, or necessarily different methods, just different cues. Training a deaf dog is really not so very different from training a hearing one, you just 'talk' in a different language.
