CARING FOR HORSES IN EXTREME HEAT – PART 2 🌞 Heat Stress in Horses: Know the Signs. Act Fast.
Following on from yesterday’s post about hydration, salt and smart summer management, it’s just as important to understand how to recognise heat stress and how to respond quickly if it occurs.
Heat stress is a serious welfare issue and can become life-threatening if not recognised and managed quickly. Horses working or travelling in hot and humid conditions are particularly at risk.
COMMON SIGNS OF HEAT STRESS INCLUDE:
❌ Raised body temperature (above normal)
❌ Rapid or laboured breathing that does not settle after work
❌ Elevated heart rate that does not recover normally
❌ Weakness, dullness or lethargy
❌ Muscle trembling
❌ Heavy sweating, or in severe cases, reduced or no sweating
If you see these signs, cooling must begin immediately.
COOLING A HORSE WITH HEAT STRESS:
(As outlined in the Pony Club Australia A Certificate Manual)
💦 Run cool or iced water over the horse’s entire body as quickly as possible
💦 Continue applying water for as long as it takes to bring the horse’s temperature back to normal
💦 Offer small drinks of water regularly, but avoid letting the horse drink a large amount at once
💦 If there is no breeze, slowly walk the horse while sponging with cold or iced water
💦 Air movement (natural breeze, a fan, or gentle walking) helps heat transfer
💦 Each application of water absorbs heat from the horse’s body and releases it into the surrounding air
💦 Continue cooling until the water coming off the horse feels cold
This process is called aggressive cooling and is extremely important in managing heat stress.
ONCE THE HORSE'S TEMPERATURE IS UNDER CONTROL:
💧Electrolytes may be needed to support rehydration
💧In severe cases, veterinary treatment and fluids may be required
Knowing the signs and acting quickly can make all the difference.
