A disc can be thrown in many ways. Two of the many ways of throwing a disc are Runners and Floaters. Runners fly long, straight, and far and have very little hover to them. A toss and fetch throw is a runner. Runners are chased down. Floaters rise up to their apex, hover for a moment, and then drop to the ground. Throws that are made in order to make your dog leap are most likely Floaters.
