Cool Tips to Beat the Summer Heat


Beat the Summer Heat and keep your cool this summer.

Summers have gotten hotter and hotter and you are not the only one who’s feeling the heat. Your horse can also feel how hot the day is and it may not be good for them. Horses tend to deal with cold days better than hot. Leaving your horse out in pasture on a hot day can cause heat stress, but how do you know if the day is too hot for your horse to handle? Try your best to beat the summer heat and look for warning signs.

Keep your horse cool and healthy in the warmer months

Every year, there are many cases of dehydration and heatstroke that can be fatal. But with proper and responsible equine management practices, you can help your horse get through summer safely and comfortably. Signs of heat stress are not hard to notice, if you just won’t ignore them. These signs can tell you so much about your horse’s capability of handling the summer heat.


Heat-Stress Signs to Look Out For

The following are signs that your horse could be under heat stress:

  • Elevated respiratory rate
  • Elevated  heart rate
  • Sweating heavily
  • Rise in body temperature
  • Lethargy


Elevated respiratory rate

The elevated respiratory rate happens as your horse tries to breathe hard forcing the air to flow past the vessels found in the lungs and airways of the horse. This mechanism helps cool the horse’s blood. However, it becomes risky when the respiratory rate shoots up to 40-50 breaths per minute or even more. If you observe that your horse’s breathing is shallow and does not return to its normal pace after resting for two minutes, take warning.

Elevated Heart Rate

The heart  action pumps out blood to reach to the skin surfaces so it can be cooled by the air in the environment. The average heart rate at rest is from 30 to 40 beats per minute. But when the heart rate increases to more than 80 bpm and does not seem to normalize after a period of rest, it can be risky for your horse.

To check for your horse’s heart rate, use a stethoscope. If your horse is standing, make him place his left front foot forward. Position the stethoscope against the chest, the spot just below the left elbow, moving as far forward under the horse’s elbow if necessary. Pay attention to the sound of his heartbeat, characterized with the “lub-dub” sound. Count the beats for a period of 15 seconds, and multiply that number by four to come up with his beats per minute.

Heavy Sweating

Sweating is the body’s way to cool off as it is a form of evaporation. It’s a good thing that your horse will sweat but it’s a bad thing if he sweats heavily and a lot. Heavy or profuse sweating can leave your horse dehydrated. On the other hand, a much worse case is when your horse stops sweating – this only means that your horse does not have a way to release the heat that has been building up inside its body. The body temperature will then increase further and further leading to heat stroke.

Rise in Body Temperature

When there is a significant rise in the body temperature, it only means that the horse’s cooling mechanisms have malfunctioned. Monitor his rectal temperature and make sure that it does not go beyond 105 degrees Fahrenheit.


When under heat stress, the blood is transferred from the vital organs to the skin surfaces to be cooled, exacerbating heat stress in the process. As a result, your horse tends to become lethargic, depressed, and may lose interest in its food – worse, your horse could collapse.


Treating Heat Stroke

Heat stroke should be treated as a serious condition. Severe cases can lead to seizures and even death of a horse. If you notice signs of heat stroke in your horse, you need to take immediate measures to help him cool down.

  • Stop the workouts; dismount from your horse and cease the exercise program. Remove tack to allow cool air to penetrate its body.
  • A cold water bath on its entire body is always helpful
  • Give your horse cold water for drinking and allow him to drink to his pleasure
  • Lead your horse to a shaded area to help him cool off more
  • Contact your vet if the signs mentioned above are not resolved despite several minutes of resting.


Preventing Heat Stroke This Summer

Here are tips to help your horse maintain its cool this summer:

  • When you ride, do it early during the day.
  • Minimize tack and if you have to put him inside a trailer, do not cover him with a blanket
  • Give your horse access to fresh and cool water all the time.
  • If your horse is set to work hard during the day, provide electrolytes in its water.
  • Keep your horse in tip-top shape. Overweight horses need more energy to move about, and so will produce more heat.

The overall health of your horse partly plays an important role in handling summer heat. Sick or debilitated horses cannot spend enough energy needed to cool off. In the same way, equine parasites can also cause health problems making your horse more prone to heat stress. Therefore it is important to make sure your horse is in great condition. Keep his deworming schedule updated and make sure you take measures to keep the summer pests at bay.

With responsible equine care, and never failing to notice obvious signs of compromised health, you and your horse can get through summer with endless fun.
