I started 2x2 weave training with Kumma 1 month ago. Today he took a jump, I made a rear cross, and he weaved 4 poles in a straight line! Next steps will be adding 3rd pair of poles, and hitting harder entries from full speed using a jump before the poles.
I don't want to hurry by progressing too fast. Kumma is a big boy, and needs time to learn to use his still developing body. He is thinking hard during training sessions, and I need to keep the sessions short. If he gets tired, he starts slowing down.
