I bought a Doberman a while back as a guard dog, as my family where having a few problems with pikeys who had parked up in a field near our house. Since we've had him nothing has been damaged or stolen from our land, so he's done the trick. I'd definitely recommend them as a breed, very friendly and obedient with people they know. Plus they are great guard dogs. A big powerful dog, with loads of speed. No robber will come near your property if you own one, and even If they do they won't get very far
