Most of the "pit bull" stories I hear of start out like this,attacking animals then later attacking KIDS/(Im guessing they confuse small kids for other animals)and or there owners.For now he needs to put a lock on the gate so the kids wont accidently get into his yard and get bit and of course letting the pit out.
I would have taken your dog to the vet yesterday!He could have internal injuries or some sort of nervre damage that could pop up later.He flips the bill!!
I would also level with him and tell him either you or he needs to call the authorites,before something serious happens later and you regret it.
