Killing neighbours dog Hi may I know what is the karma of killing a dog please? 

My neighbours dog starts barking from 5am daily and I don't get enough sleep. I am so tired at work and cannot focus. I've tried soundproofing my walls and using ear plugs  but they don't work I can still hear the barking.

I've spoken to the neighbour but he tells me that he is a human and he can't ask ask his dog to keep quiet (whatever that means).

I am at my wits end, I am so tired, I never get enough rest. Can I kill the dog? May I know what is the karma for killing a dog?
