as disgusting as that may be, IMO, animal cruelty is one of the worst things that a human can do. Dogs are ignorant to their actions and only have an approx. 5 second memory. So by the time that you figure out what your dog did..and you punish him, he'll wonder what it's for. I realize that some of you are obviously just kidding, but man, I cant even joke about harming my dog. Just my two cents
With that said..i'd burn the car.
