I'm sorry to hear your first class didn't go well. I confess it's a little odd to start with the tunnel but every instructor is different. I don't think there's a right or wrong on what to teach first. As for the waiting/distraction. Targeting helps to keep the focus on you. My class gave each of us a clear plastic small plate that we taught the dogs to touch then gave them a treat. Since it's clear it teaches them to focus on your hands. As for the waiting, our instructors recommended bring a favorite toy that you can play with him. Something like a rope to play tug of war, etc. Gets rid of energy, keeps focus on you, and is a reward for him. It works really well for an extremely hyper aussie in our class that if his owner let him would just sit there and bark and whine the entire class.
