I'm in desperate need of help....my BC goes absolutely crazy while waiting his turn to run the agility course. I've had my trainer tell me to turn him around, cover his eyes, but he's impossible. He's so strong he turns back around and barks like crazy. I've tried to get his attention by trying to get him to do tricks or watch me, but nothing works. He is so focused on the dog running the course and I can't break that focus. By the time it's our turn I'm so exhausted from trying to control him. Do you have any ideas as to what I can do.
