Skin issues are common in golden retrievers. If your dog needs a special shampoo (prescribed or recommended by a vet) you will probably be bathing your dog once a week until the issue is resolved, or at least controlled. If there are no skin problems, it's best not to bathe your dog more often than every 2-3 months, unless he or she gets visibly dirty (romps through a mud puddle, etc).
