If someone came sneaking up on the house at night, especially a group of people sneaking with guns, my 2 big dogs would naturally assume someone was up to no good, and they would protect their humans.
I hope none of this ever happens, believe me. I can't say what I'd do if my dogs were shot because I would get banned.
Although I'm sure to catch heck for my #18 post. I agree with you. In fact, after the Ruby Ridge incident, I have wondered many times about the act of preimptively shooting someone's dog. If my dog were shot in such a scenario I would consider it an attack on my life (why else kill the dog). If the police were to mistakely raid my house, I knew it was the police as they came in, and they shot my dog, I'd wait until charges had been dropped, reparations made, and then I'd go find the policemen, while he was off duty, and get my self arrested for assault.
I find this whole business of shooting dogs however, to be a completely separate issue from enforcing the laws against illegal drugs.
