( Around 10 am ). While working him I noticed he was breathing slightly heavily but no more than a normal horse being worked who is 1200 lbs and out of shape.
After the round pen, I walked him through the barn and tied him up while I went to get everything ready for a bath. ( I generally hose the horse off almost daily to help keep them cool but decided a bath was needed ) While bathing him, I noticed his breathing was more of a quick short breath through the nose ( try sucking air through you nose and letting it out quickly, that's the exact noise he was making )
I mentioned it to my BO who told me she noticed it too. Now mind you this horse hasn't been worked by a human in a while ( rescue from kill pen ).
Could this be a side effect of being so out of shape?
Could it be the heat ( 106 daily average with humidity. )?
Could there be something else going on?
