Your dog needs to get out more. Kennels and doggie day care are awesome. Mine loved going to the kennel when I'd travel. He played none stop and would sleep for a day after he got back. We'd have to be running fourteeners for him to be that tired. Your dog is missing out because your paraniod. Give him a shot or a pill and let'em party with the rest of the pack. Quite being so lame.
And do everyone a favor and don't spent the paraniod disease to others. Next you'll be giving your dog bottled water.
