I have a Qtr. horse gldg that is 5 yrs old and run on barrels. He has had some trouble before and still does have a problem after exercise with catching his breath. He pants and this lasts about three times as long as other horses that are in worse physical condition than he is. I believe it is probably related to the fact that he does not sweat much if any at all where as most others on same exercise program have worked up a good sweat. What I would like to know is what could cause this and how it might be treated? He has been to a vet and checked over and they say he may have some asthma but not enough to cause this much problem and not the lack of sweat. This problem has occcured during winter and summer months. Any input would be appreciated.

Thank you

Amy,
Your horse may have anhidrosis which is a condition where horses incompletely or do not sweat at all. Your local vet can help you diagnose this condition by history, clinical signs, and intradermal skin testing (using epinephrine or terbutaline sulfate).

Good Luck,
