OMG. That is amazing! My Golden was sort of a dunce at agility. He loved the jumps, the weave and the A frame, but he was scared to death of the dog walk and the teeter totter and just refused. Finally, we just stopped going because I decided that if he wasn’t having fun, what was the point?
He saw his “friend”, a GSD, fall off of the dog walk; and that just ended it for him. It is not like I could pick him up and put him on the aparatus at 80 lbs. LOL
What an enthusiastic little competitor!
The dogwalk is definitely one of the contacts that give advantage to the toy dogs. The board is wider for them than it is for the bigger dogs. So they can fly across, where the big guys need to slow down and be more careful.
I think you were wise to listen to your dog. Perhaps you could try a different sport he would like - Rally or even tracking, for example.
