i will not shot at a moving dog.dog was in contact with mine, in the road.took several kicks to ribs and head.putting gun to him would not have been an issue.just really hate dog getting punished for owners lack of responsability.Did learn to call 911 and havee an officer respond for legal and financial reasons.talking to animal control tomorrow as they have jurisdiction after attack. as far as PS would have been to late, asp is serious consideration only i fear maiming dog instead of quick death. plus the swing and movement of dogs seems more likelyto hit my own dogs.
