You leave your dog outside unattended irresponsibly and then you solve that problem by shooting and harming other animals instead of watching your own.

And for the record, NO, I wouldn't put a shock collar on a dog. That's horrible too. No idea why you'd assume I'd be cool with that.

How are none of you in the comments bringing up the fact this psycho said he keeps an airsoft gun by the door to shoot dogs with? OP please spend some time learning about responsible pet ownership and treatment of animals or if you're not willing to do that surrender your dog to a no-kill shelter.
