I was at our local pet store and came across these dog sitter videos. You put them on for the dog when you leave and they have about 90 minutes of interesting stuff for your dog to watch and listen to. They claim there is 8 different layers of sound put on so it would be interesting for them to listen to since they can hear so much better. It is all filmed by "doggie cam" so they get the dogs eye view. They mostly show other animals, but one had a part about agility and other dogs. On the back there were pics of several dogs watching it, and one was a B named Kozmo. I thought it was interesting and wondered if anyone has seen them or has tried it out?
