Today I tried to lunge charlie, and I have been for the past few days and he will go around the circle like one or twice if im lucky then turn in to face me and stop. I turn him out again and crack the whip when he seems like he's about to stop but he just ignores it and turns into come towards me again. Today he did one circle and stopped, then twice doing half a circle and stopping with his ears back he calmly walks up and bites the crap out of my forearm I mean HARD. He has never done that before! I have a huge hideous bruise about the size of a tennis ball forming on my arm now. I am not sure if I am doing this lungeing thing wrong or if Charlie doesn't understand?
I have tried to lead him in a circle a few times and let some slack out to make him eventually get out into a circle at a walk, but he insists on staying right next to me. What should I do? I popped him HARD on the shoulder after he bit me, I'm not going to let him develop a biting habit!
