Smoke is an unhealthy combination of carbon dioxide, carbon monoxide, soot, hydrocarbons, and other organic substances. Smoke particulates can irritate horses’ eyes and respiratory tracts, and hamper their breathing.

The simplest thing you can do to limit the damaging effects of smoke on your horse’s airway is to limit your horse’s activity when smoke is visible. Increased airflow and turbulence that accompany athletic activity can significantly increase the inflammation and damage to delicate cells lining the respiratory tract. In addition, if possible, misters and fans can be used to improve air quality in your horse’s environment.

Human air quality advisements can be applied to your horse as well. If your eyes are burning and you smell and taste smoke, then assume that your horse is feeling as uncomfortable as you are.

Most importantly, when smoke has been particularly heavy, remember that it takes time for airways to recover fully. Four to six weeks can be required for airways to recuperate from severe smoke exposure, and early return to exercise can delay healing and increase the risk of long term airway damage.

The best way to combat heat and smoke is through hydration. You can:

1. Provide clean, fresh water at all times

2. Water your horse’s hay and feed grain as wet mashes

3. Put sprinklers out in turn outs to reduce dust and smoke and increase moisture in the air
