Dogs Playing Ultimate Frisbee - The Jackson Gattis Biography

"You'd have to train them when to catch the frisbee, like if you were throwing it all the way down court you would have to somehow signal the dog to go and catch the frisbee, but if you were just doing short passes down the field you wouldn't want your dog to try and bite your hand off - you'd have to have some way of telling the dog when to catch the frisbee, if it didn't catch it in the goal, you'd have trouble getting it back from the dog because it would probably want to walk, and you'd get a carrying penalty and then the disk would just go to the other team."
