Ive had the same problem on a couple leases in the past and am running into this problem on my private 80acres this year. Ive seen the owner of the dogs this year and spoke to her father about seein em chasin deer and even he said shoot em n leave em layin! Ive shot a good many k9s chasin deer..before im bashed I am a dog lover. Im raisin a 4 month blue heeler at the moment and would hate to see anything happen to her. But at the same time, if dogs are runnin deer to me there no better than coyotes and I dont hesitate to kill them when I see em. When dogs pack up and run game there wild especially if there not huntin dogs ie beagles, which is my case right now. Talk with the owners, but that wont help ive tried that in the past. Theres a reason they let the dogs run free...they dont care.
