Hi all. I was taught a long time ago how to stop the all out run and tackle berner bump. Simply to take my stand and put a knee up and let the pup try to tackle it. It will knock the wind out of them immediately. I had to go through this exercise quite a few times until one and one equaled three in my berners brain. Now, upon the sight of the runner, I still present my knee but no one wants to hit the ground gasping for air and neither of us get hurt.
