I'm thinking of feeding my dog the bones of my enemies.
That is pretty morbid. Why are you killing your enemies and feeding them to your dog?
I often hear dogs also enjoy bones. Once he ate some chicken bones while I was sleeping, so yeah I've got the idea.
So you want to commit murder just to feed your dog, there is so much wrong with that even if you consider the people your enemies. If you just want bones for your dog you could check with a butcher, I'm sure you can get some beef or pork bones your dog will enjoy.
Okay, I'll ask a butcher but what would happen if I went ahead with my evil plan.
They would probably report you to the police. You should look into humane ways with dealing with people you don't like that won't turn you into a murderer. If its truly that bad, try getting a third party or authority involved to help solve things in a civil manner.
