This is a good response. The hamburger thing is good. It doesnt change the fact that the guy is a jerk though. I have a feeling if you tell him you have poisoned food he would just kick it into the river. There is more of a problem with him than just the dog. I have a feeling though that the reason that he acts the way he does is because he knows the dog will back him up in case of a scuffle. poor poor dog.
