Got a rifle or shotgun? Wild dogs of any sort are nothing to mess with, they don't have the fear of man that coyotes do, which makes them dangerous.
If I had your problem, and needed a good all purpose rifle that could handle wild dogs and coyotes, I'd pick up a .223 bolt action. Savage and Stevens (same company really) make a couple very nice models that shoot very well, and are affordable. .223 has very mild recoil, is cheaper to shoot than more high powered rifles, and if you get good with it you can make a shot all the way out to 400 yards.
If the problem dogs are within 50 yards, get a shotgun. If they are further out than that, get yourself a rifle. Wild dogs will happily kill a human adult or child if they are hungry and belligerent.
