you can send a dog in to retreave a animal if its bean shot badly. so what if you shoot it and your not sure if you have hit it or 'not' so you send your dog in
So the moral of the story is when your after hares take a gun and say your lurcher is a retreaver and fire shots of every now and then so people dont suspect anything.
Or be like everyone in my area and take a lurcher and say fu*k it
