What kind of place was this? A dog that bit a kid and a teacher in separate incidents, and chased other kids? It doesn't sound like you have enough damages for a lawsuit against the school. Why don't you see if you can get a court order to have the dog picked up and killed? Maybe the owner will put up a fight about it and the police will knock him around a little. If your state allows punitive damages maybe you and the teacher that got bit could go after the owner.
Patriotism (and religion) is the last refuge of a scoundrel.
