I think this must be a prototype because it looks like there are a number of exposed moving parts and it’s not exactly sleek in terms of design, but I love the concept!!  Oscar isn’t much of a fetcher, but I can see how this would be really great for dogs that are fetching/tennis ball obsessed.

I especially love the display screen, so that you can see how many balls your dog fetched while you were at work! 

I wonder if it was hard to train the dog??  Very good idea…
