I
gotta second that! The property I used to lease (before moving to Nicaragua!

) had TONS of wild dogs! During dear season, it was easy, because many guys carried rifles. However, I primarily hunt with Longbow and they are not know for "stopping power" on a wild dog!

I have been attacked twice by dogs when I did not have sufficient firepower . . . never again!
First time, I only had my longbow. I was still hunting when a line of eleven dogs came by. It was my intention to let them pass but, when they caught my scent, they charged in. I was able to pin the lead three dogs to the ground (less than 20 feet) and the others scattered. It scared me to death and I swore, in spite of the fact that it is illegal to carry a firearm during bowseason in GA, that I would never enter the woods without a firearm again.
Dummy me

went in the woods squirrel hunting later that year with ONLY a Remington 597 .22 LR. While hunting, I had a Rottwieler looking mixed breed charge me. I tried yelling and throwing stuff but it kept coming. At about 10 feet, I unloaded the 10 shot clip into it's head and shoulder area rapid fire. (Rifle was scoped so I rolled it to the side and sighted along the barrel.)
I did not stop the dog! I had to turn and run with the dog in pursuit (Slinging blood EVERYWHERE!) while trying to reload the clip. Once reloaded, I turned and shot the dog
four more times before he fell!

Now, needless to say, I carry more firepower. My usual carry is an inexpensive Rossi .357 magnum snub-nose. It is ONLY intended for close range protection and is an accurate shooter with good heft but easily fits in my fanny pack. My wife is very comfortable shooting it with .38s and, with a premium load like hydra-shocks, it should be plenty to stop a dog.
Don't take the risk of making a wild dog wilder with insufficient knock-down power!
