I just got off the phone with my buddy whos the warden here & he said that the dogs, not the coyotes took the antlers off. He also said he suspects from the pics that the buck was going to shed soon, thats why the dogs were able to break them like that. He also gave me the green light to kill any dog we see out there. We know all our neighbors pretty well & these dogs dont belong to anyone we know. So our assumption was someone dumped there dogs out there to be rid of them. He also asked me to bring a dog carcass in to him so he can have them checked for chips. Once the snow melts in the next day or two, Im going to go back out & search for the antlers some more. Im just hoping to find them before the critters do.
