No way I could shoot someone's pet. Owner ignorance or not.

My buddy had this issue 2yrs ago....dang near everytime he went out. Finally, he got down and caught the dog and called the pound to come get him.Owner got fined when he came to pick him up....and he didn't have the problem anymore. Not sure if they will do that where you are. Def pursue that other law....might work for you. Sorry to hear it, I know its frustrating.
