Horses may wheeze for several reasons. The first is a airway obstruction like mucus blocking the airs pathway. Another is due to paralysis of certain parts of the throat which causes the horse to make a sound called roaring. Horse can also wheeze if they are sick, in pain, or have learned that making that particular sound will get them out of working.
