lol danz. If you have a .22 they sell a bird shot load for those that will turn a dog the other way but. I wouldn't suggest shooting that load often as it will mess up the rifling in the barrel over time. I have a shotgun but I like my .22 because it dosn't make alot of mess but still leathal. I'm pretty good with dogs but hate cats because they've killed so many of my birds. I have no problems killing a cat. As far as your dog problems go try yelling at it, banging a couple pots togather, smack it with a broom a couple times, if all else fails I would try a low power bb gun. Dogs learn a little easier than cats and unless they are killing things or being aggressive toward kids I wouldn't use leathal force.
