It seems to me you are down to just a few options. Unless the dog bites you, probably the sheriff or animal control will do nothing. You have already gone the sheriff route and animal control will have to catch the dog out of his yard. I hate to get pepper spray but did several years ago because the person I was dealing with was unreasonable and sounds like you are dealing with the same type person. Lastly, you can just take your dog somewhere else via car or golf cart until things change with this situation. If by cart, I would have the pepper spray handy. If the man is not well, things could change sooner instead of later.
