Some interesting points ! I trailed a dog years and years ago never jumped , I took it out and out it would try and smash through gates fences any bloody thing in the end his heart got the better of him he started to jumped so much game I consider ! But the time he took the perfect hurdle was out of sight after something straight under a bloody car ! You could and would not stop that dog , which was the end of him ! So I agree with alot on here for once and to me a game dog in my experience would run through fire after game ! Honestly I don't know the dog or you and haven't seen it work , but
