text:  your time frame to try and really do any type of stamina or even sprints gets pretty short. I think when it's really hot, I focus more on doing a few quick sprints with the dog and then letting him cool off completely. And with those sprints, you know, we're throwing the bumper in the water, you know, 20 yards out, 30 yards out, something like that. Real short, quick, let the dog swim out, get it, come back.
