Be careful out there!
I'm sure everyone has noticed the wildfire smoke from Canada and MN that is all around us today. People ask can I ride with smokey skies. This image is an easy to read guide from Smartpak to help you make those decisions.
Here's more information of the effects of smoke inhalation from air pollution in horses. Smoke is composed of chemicals and particulate matter. Different types of wood, vegetation, houses or buildings, plastics, and other combustible materials all affect the composition of smoke. Many toxic chemicals are produced, some of which can be fatal in high doses and when inhaled over long periods.
The particulate matter found in smoke tends to be very small in size, which allows it to pe*****te deep into the lung tissues. For this reason, smoke tends to be more harmful than some other airborne particles, like the dust generated from riding arenas or roads.
Horses that are exposed to wildfire smoke can suffer various degrees of injury ranging from mild irritation to severe lung tissue damage. Owners should carefully observe their horses for any signs of respiratory distress, which include:
Respiratory rate consistently over 30 breaths per minute at rest (not during or right after exercise)
Labored breathing (increased effort from the abdomen/rib cage)
Flared nostrils
Deep or repetitive coughing
Nasal discharge that is yellow/white in color
If you notice signs of respiratory distress in your horse, contact your veterinarian as soon as possible.
The symptoms of respiratory distress are notable and most commonly experienced by horses in close proximity to wildfires. But what is less obvious and more common is continued and repeated exposure to air pollution caused by drifting smoke. It is not yet well known how this might affect horses’ athletic performance and long-term health. The best recommendations at this time are to minimize work intensity (and therefore the amount of air pollution inhaled) depending on the AQI.
