It's final

This is it. This is the official day of the CGC test and no going back in time. At 6:45 (Central time) Peanut and me will be testing our obedience training and skills. I gotta trim Peanut's nails, brush, brush, brush, brush teeth, brush hair again, clean ears, trim paw feathering, brush hair again. I am excited but nervous and doubtful at the same time. The worst part is that no treats are allowed so it's going to be harder to keep him from screwing his tricks up. I am deeply worried inside and out. Any advice to keep Peanut from "breaking" his out-of-sight sit-stays?
