What’s going to happen to me and my dog if my dog attacked another dog?

My dog got out of our fence and attacked another dog on their property. A man from a few streets over shot her in the head and she took off running. The family of the other dog took the dog to the vet that night. I haven't heard anything since except from animal control that we were going to receive an animal at large ticket. This is the first time this has ever happened and I’m scared. She is not a mean dog. The only way she is going to hurt another animal is if they come after her first.
