Treats are a good start. A hiking staff can be very handy also. Just keep it between you and the dog. They have a hard time with this simple obstacle. Also, most dogs are "bluffing" and are terrified of loud cracking noises, fireworks, gunshots. BTW, urban/suburban dogs would probably be much more of a hassle. I find country and farm dogs to be much more balanced and less aggressive. If you're carrying a shotgun or pistol, great. If not, bearspray, maybe some fireworks, and an easily accessible fixed blade knife. But again, IIRC the only accounts I read of "packs" of dogs going after humans happens in cities.
