When dogs are at that age, if they have a strong bond with their owner, all that they want to do is please, please, please. I trained my dog for agility trials and only used treats twice. All the other times were rewarded with playing, petting, verbal praise, and/or a non-food "treat". She loved playing tug of war with my socks, so after a particularly good run, we would play tug of war for a while. I started training her at 8 months old, and it took about 3 months of daily training to get her doing the course cleanly.

In that vid, I don't agree with him having a satchel of treats in plain sight of the dog... dogs aren't stupid.. they know that the little black thing on the human's back means food. When I was working with Ouija, and when I'm working with any dog for that matter, I ALWAYS keep treats in a bag in my pocket. That way the dog has no visual/odor indicator about whether or not I am carrying treats or not. I'm not dissing the guy, the dog seems very well trained, but I'd be curious to see how much difference there would be if he was not wearing the visible treat pouch.
