• Those of us who have worked as veterinary surgeons in very hot climates – e.g. California, China, etc, are only too aware of the potentially dangerous effects that the extremes of heat can have on a horse. Indeed as our own Irish climate continues to show tendencies to intermittent extremes in heat in recent times, horse owners need to be aware of the potential extra challenges and risks that extreme heat can present to a performance horse. Riders and trainers whose horses travel and perform regularly on the circuit abroad – in racing, show jumping, etc, have acquired considerable experience in coping with this complex area.

    • What are the main problems that can affect a horse’s performance in extreme hot weather?

  • Like all mammals, horses need to keep their internal body temperature within a narrow temperature range. If they overheat, they risk permanent damage to vital organs and muscles, and may even suffer collapse, heart failure and death.
