Check your local laws carefully. Shooting to wound, or causing injury on purpose, is animal abuse here. Killing a dog who's harassing or killing livestock is legal.
At least, continue to call AC! This dog may have decided that your place is part of his territory, and threatening a person (child!) is not good. This should get results from AC or the sheriff.
