You may be right jack but no dog comes out the womb knowing what to do it only takes 1 good hit in the wrong spot and it never gets another chance. I know peoole who dont use even a yard collar but the dogs are always down due to cuts. All 3 of those dogs in the pics have tears from the weekend and the brindle dog hurt his back. None of them were bred for pighunting the brindle is my game plug i spoke about before to loose him on a pig would be a waiste the others are still to young to prove there worth but a pig dog is not bred on holding technique it is bred on finding,holding,speed and stamina i couldnt really care how he holds it as long as its on there..
