Retrieving wounded dog on private property

I have dealt with a situation that is a little like yours. I had a cow man on a adjacent property shoot at our dogs and he didn't know that I knew his boss who had the surface rights, grazing and hunting. We confronted the guy that did the shooting and he claimed they were chasing deer which we knew was a lie because we had seen the hog they were on, he was not planning on us standing in the road when he came out of the river bottom so he was stuttering a bit and you could just tell he was lieing. Things got a little more tense because we had one dog that never came back in and we thought was dead. The dog was found cut down the next day at a neighbors house luckily. I called the land man and a short while later we got a phone call appologizing. Luckily no dogs were hit but just another case of lieing and crooked people making harder then it needs to be. I hope everything works out for you.
