A trick contest, who will win? Kaiser and Nana will have a contest in this video and see if you can guess who wins the contest. This is an awesome idea. They get to do certain tricks and compete against each other. Competition is always a good thing and creates a fun environment for all. These two make me laugh. I have said it before and will say it again, dog trainers completely amaze me. This world is a better place because of dog trainers. There are people like myself that have no idea what to do when it comes to training.
