"Water accounts for approximately 60% of a
horse's total blood volume, so losses through sweating can quickly cause
significant dehydration if not addressed. A horse can easily lose 12L of fluid
per hour of sweating during strenuous work."
Charlotte Radley, MRCVS
Along with water, electrolytes such as sodium, chloride and potassium are lost too. If these aren't replaced, horses may be slower to recover, show reduced stamina or be less willing to perform.
A common misconception is that a horse will always drink enough if water is available. In reality, many horses drink less when travelling or away from home, where unfamiliar water and routine changes can quietly reduce intake before a horse even begins work.
"Post-exercise, horses often don't drink enough to replace fluid lost via sweat. Providing electrolytes can effectively induce water consumption and rehydration, while replacing the minerals that have been depleted."
Jennifer Little, RNutr
Early
signs of dehydration can include:
Prevention starts well before the lorry is loaded. Ensure constant access to fresh water at home and consider soaking fibre feeds to boost fluid intake. At events, offer water regularly rather than waiting until your horse seems thirsty, and take familiar buckets or water from home if they're reluctant to drink away.
Alongside water, feeding a balanced electrolyte supplement before travel or competition, and again after significant sweat losses, helps maintain fluid balance. Equell's gut friendly UltraElectroS replaces key electrolytes lost through sweat, supporting hydration and recovery in hardworking horses year-round.
Success is built on strong foundations. Ensuring your horse is properly hydrated before, during and after exercise is one of the simplest steps you can take to help them feel, perform and recover at their very best.

- tacky gums,
- darker urine,
- reduced appetite and
- prolonged recovery after exercise.
