Read below to learn more about how heat stress affects horses, and some tricks for recognising, treating, and preventing heat stress this summer. Always be sure to check with your veterinarian for any questions or concerns regarding your horse's health.
Summer is the perfect time to get your horse in peak condition. But as levels of humidity and temperature soar, so do the risks of your horse suffering heat stress. Here's what you need to know to safeguard your horse
THE CAUSEYour horse's muscles generate heat when he's active, and sweating is his body's cooling mechanism. High levels of humidity and temperatures can sometimes make the cooling effect of sweating less efficient. Your horse may become dehydrated, lose electrolytes, or overheat. |

|
HOSE HIM WITH COLD WATERHose him down the neck, shoulders, and under the belly area to increase heat transfer. |
|
ENCOURAGE HIM TO DRINK WATERWater must be provided at all times. Lightly worked horses can drink 25-60 litres a day while those working in humid conditions can chug 50-70 litres. |
|
PROVIDE ELECTROLYTES DAILYNot only will electrolytes help him recover from the salt that is lost in sweat, it will also trigger his thirst, making him want to hydrate more willingly. |
|
GIVE HIM ACCESS TO COOL BREEZEMake sure that he has plenty of ventiliation. Place fans in barn aisles or in front of stables, and keep the barn doors and windows open to let the air flow. |
|
GIVE HIM ACCESS TO SHADEIf your horse is out in the field, ensure he has access to natural or structured shelter to provide shade so he can get out of direct sunlight. |
