My sister decided to take the dog for a walk, on the walk the dog and another dog started lunging at each other. Our dog hurt the other dog so that he needed stitches. The owner was hysterical and still is very upset. We gave them our information and when we went over to talk to them they said they are calling the police because they want our dog to be put down. They proceeded to tell us what bad owners we are and how our dog has not been socialized properly. This is his first time ever attacking or biting anyone or anything. Our dog also has scratches and little bites on his body but not like the other dog. I really do not want my dog to be put down. We offered to pay all bills for the dog. Can they have my dog killed?
