Just to add; I have a Bow stand about 600 yds in the bush from that spot, and in the 12 yrs it has been there with a trail cam over a bait pile I have maybe two pictures of him (or his predecessors) at the stand. And they were taken shortly after I had been out to throw down some corn, so he had followed me out and then followed me home.
Very few working breed dogs have any interest in chasing wildlife...why do you keep harping I need to tether him to the barn or walk him on a leash...???
