Looked to me as the driver ran ove the dog on purpose, and that would be considered animal cruelty. Which IS against the law and you do usually get jail time for, I have actually seen people serve jail time for less. And yes, the dog shouldn't have been running loose, but the dog was on his property, not saying that it is ok but like I said, it looks as if he hit it on purpose and then backed over the dog again. An accident is one thing but this is breaking the law.
