I love the commercials and this video was wonderful. I sent the link to a dog group I belong to, mentioning that a Clydesdale was doing weave poles about 4 minutes in. The video also has some wonderful examples of how they shape the behavior when training the horses. For those of you unfamiliar with the term 'shaping', a good example in the video is where they have the two horses jumping through a sheet of paper with a big heart painted on it. Later, they show the Clydesdale alone, running through a clothesline hung with sheets. I'm sure there were a number of other steps involved in that, but you can get the idea.
