How much water do horses need?
On average, an adult horse should drink 25-50 litres (7-13 gallons) per day.
The exact amount depends on several factors:
- Body weight: naturally larger horses drink more than ponies.
- Diet: horses on dry hay or high-fibre feeds need more water than those on pasture, which is 60–80% water.
- Medication and supplements: some can increase urination or affect water retention, meaning losses must be replaced.
- Workload: exercise and sweating raise water requirements.
- Weather: hot or humid conditions can double water intake.
- Life stage: lactating mares and growing foals have higher needs.
A hard working horse in hot weather may drink 70 litres or more per day to stay properly hydrated.
