With the fires burning across our area, what you can’t see may be just as concerning as what you can.
Last night’s AQI was 183. For perspective, many racetracks suspend racing and workouts when the AQI is over 175.
We cannot train through the smoke.
Wildfire smoke can cause significant airway inflammation and particulate exposure that may not show up immediately. When I lived in the Northwest, managing performance horses during wildfire season was challenging. What was especially frustrating was seeing horses that seemed fine during the fire, only to lose stamina weeks later. 4–6 weeks down the road, we would sometimes be dealing with pneumonia.
I remember one horse evaluated for poor performance weeks after wildfire smoke exposure whose BAL showed plant material/fungal hyphae in the lungs. We don’t always realize how much our horses are breathing in, whether from wildfire smoke, dusty environments, or even inside a trailer.
For now, let your horses rest.
• No strenuous exercise or training
• Nebulized saline can help with airway clearance
• Horses with a history of asthma/IAD may need corticosteroids and/or albuterol—talk to your veterinarian
• Wet hay and bedding to reduce airborne particles
• Keep horses untied and with their heads down as much as possible to allow normal mucus clearance
• Consider Adequan or Zycosan as part of an anti-inflammatory/supportive plan when appropriate for the individual horse
• Vitamin C and magnesium supplementation may also be considered as part of your horse’s overall supportive care
If you notice coughing, increased respiratory effort, nasal discharge, decreased stamina, or a change in performance, have them examined.
The effects of smoke exposure don’t necessarily end when the smoke clears.
We need to be responsible and protect our horses now, so we aren’t dealing with the consequences weeks from now.🐴🫶
