Have a 4 year old mustang that started coughing about 4 to 6 weeks ago when he was eating. I then started to notice that he coughed out in the pasture and at night as well. Called vet after 2 weeks, we decided that it was Hay we had purchased from a new source. We changed him back to some of the original hay, but the cough continued. We also are wetting his feed but no change. No nose discharge, normal eating, playful, active, no visible outward change and no temp. So after 2 weeks, purchased anahist and a sulfur block in his stall. Been 4 days and no change. Also no new horses to the farm, no feed or hay changes, so.... Any suggestions??
