i live in the sticks. shooting dogs out here is fair game. my neighbor shot my dog 200 yards out because it went on his property. i'm glad i was not home at the time as it would have turned ugly. shooting a dog is ok as i had no recourse to my problem. i'm not sure how you would stand in the city shooting a dog on a leash though.

i know it's not the dogs fault but when my neighbors dog crosses my fence i will be returning the favor.
