CDSP's tagline is "the sport your dog would choose". Why? talking and treats. Obedience is great, a well performed run in a trial is a thing of joy and beauty. John Q Public stares in amazement, beginners wish for such a performance. And dogs think "well, that was stupid, where are my treats?". Formal Obedience aka AKC, UKC there is no talking. Judge says "forward" and you zip your lip till "exercise finished". There are no treats, just the party in the crate after the run. In CDSP, Companion Dog Sports Program, there are both, talking and treats.
