Just got a little snippet of one of our runs from a friend. Here's the link.
This one is where you are standing there waiting for the judge to tell you to move forward (that is why Denise is randomly chatting at us and I'm supposed to do my thing whenever -- not just when the judge stops talking) and you surprise your dog with a hand touch (build energy) and then run and the dog catches you. The result is a dog that is ready to go at any moment and an excellent first step from a halt.
He was getting pretty tired as well as mentally drained - it was right before lunch - so I opted to throw a cookie versus running and having him catch me. A cookie toss will always wake him up! Not only that but he is big and much faster than me, so it's not as exciting for him and doesn't create as much go.
