Wow! My dogs have that kind of enthusiasm for getting the lake, but I've never met a horse who did.
Oh, I did. The late and much-missed HRH Avery, my OTTB. We had a pasture pond that was about 15 feet of shallows and then a huuuuge drop-off down to a depth of about 12 feet. I would lead him down there on a lunge line and pay it out... He'd start cantering through the shallows and then give a HUGE push off the "cliff" into the deep end! It was *adorable*.
