Smoke pollution and your horse
Following the recent fires across the Welsh valleys, we’ve had a few enquiries about whether smoke pollution could affect horses.
The good news is that most healthy horses exposed to smoke for a relatively short period will be absolutely fine. However, smoke contains particles and irritant gases that can affect the respiratory tract, particularly in horses with pre-existing airway disease.
How can you monitor your horses and donkeys?
Keep an eye out for:
• Increased respiratory rate or effort at rest
• Coughing or nasal discharge
• Flared nostrils or abdominal effort when breathing
• Reduced exercise tolerance
• Noisy or laboured breathing
A normal resting respiratory rate for an adult horse is approximately 8–16 breaths per minute. If your horse is consistently breathing faster than this at rest, particularly once they are away from the smoke, or you notice increased respiratory effort, contact your vet.
What can you do?
If smoke levels are high:
• Keep horses away from areas where smoke is concentrated where possible.
• Improve stable ventilation, while avoiding directing smoky outdoor air into the stable.
• Avoid exercise while air quality is poor, as increased breathing rates mean more particles are drawn deeper into the lungs.
• Provide plenty of clean, fresh water.
• Feeding forage from the ground can help encourage natural airway clearance.
• If appropriate, soaking forage can help reduce airborne dust and particles around feeding which can add additional irritation to the airway.
• Allow your horse plenty of time to recover before returning to normal exercise.
If your horse has a history of equine asthma or other respiratory disease, they may be more susceptible and may need additional management.
