Horse hot weather
Quick answer
In UK heatwaves, horses need **constant shade, unlimited water, and reduced workload**. Dehydration increases colic risk. If breathing stays fast at rest or your horse is dull and not drinking — call your equine vet the same day.
Key takeaways
- Many yards reduce or stop work when the combined heat and humidity make cooling difficult. Ride early or late, shorten sessions, and ensure unlimited water before and after.
- An adult horse may drink 25–50 litres daily — more in heat and after exercise. Constant clean water must be available; dehydration worsens colic risk.
- High respiratory rate that does not slow at rest, elevated heart rate, dullness, reduced sweating (in some cases), or collapse. Call your equine vet immediately.
