Watch how this horse's breathing changed in just two weeks following treatment for equine asthma!
In recent weeks, the team at Surrey Hills Equine has seen an increase in horses presenting with equine asthma, likely associated with the prolonged hot, dry weather and resulting increased dust exposure.
Clinical signs can include:
- Reduced performance or tiring more quickly during exercise
- Coughing
- Nasal discharge
- Faster or more laboured breathing, even at rest
The first two videos show this horse during a severe asthma flare-up. The owner recognised the signs promptly and contacted us immediately. Following veterinary treatment and appropriate environmental management, the third video shows the same horse just two weeks later, breathing much more comfortably. This horse can now return to hacking in the countryside with their owner.
Although equine asthma is common, several respiratory conditions can produce similar signs but require different treatment. Your vet may therefore recommend further investigations, such as airway endoscopy, a tracheal wash and/or bronchoalveolar lavage (BAL). These procedures can usually be performed at your yard and help confirm the diagnosis, assess airway inflammation and identify any secondary infection.
Treatment is tailored to each horse and may include corticosteroids to reduce airway inflammation, bronchodilators to provide symptomatic relief by opening up the airways, or inhaled medication delivered through specialised equine inhaler systems. In selected cases, allergy investigations and allergen-specific immunotherapy may also be appropriate.
Environmental management is just as important as medication. Unless dust and other airway irritants are reduced, clinical signs commonly return once treatment stops. Good management can reduce flare-ups and often decrease the need for medication.
If your horse is coughing, breathing harder than usual or simply not performing as expected, don't ignore it. Early diagnosis and treatment can make a significant difference to both performance and long-term lung health.
