A shotgun and SSGs worked very well for me when hunting deer. You don't survive even a single direct hit from that.The shot gun is great, but wouldn't you like a security camera to capture those precious moments of making someone crap their pants?
Your buddies look like they mean business. Good looking dogs.
We had Rottweiler's growing up. They kept the house safe for sure and when not guarding the house, they we much better to pet than security cameras. However, I hope with our new place to get some cameras installed so if anything happens, at least there's a better chance of catching the person.
