I was working my horse Brandon pretty hard yesterday in the round pen, and he was snorting/panting really loud after just a few minutes work.
He is 16 years old (I just got him in Jan) and hasn't been worked or ridding in about 5 years, he is also overweight. We are working on that.
So is it probably just the equivalent of a fat guy on a treadmill or should I be worried?
There was no coughing, just really loud, heavy breathing.
