for keeping your horse cool this summer
While the sun’s glorious rays may leave us jumping for joy, and our saddles, we must be vigilant about ensuring our horses’ well-being. Here are some top tips to avoid the dreaded heat stroke, and ensure our four-legged friends have as much fun in the sun as we do!
What is heat stroke?
Heat exhaustion is characterised by:
1. An elevated body temperature (hyperthermia; a temperature exceeding 41oC/105 F);
2. An elevated heart rate (tachycardia; the normal heart rate of a horse is 36 – 42 beats per minute, although this may be higher in smaller ponies)
4. A tired, unresponsive horse;
5. The horse’s gums will feel dry and tacky; if you press on them, the area under pressure will turn white, and the time to return to normal colour will be longer than in a non-thermally stressed horse. Vets may describe this as a capillary refill time in excess of 3 seconds.
If there is no intervention, the condition may escalate to heat stroke where the horse may stagger, appear depressed or, in extreme cases with central nervous system damage, collapse and have convulsions. This is a serious medical emergency that we have the ability to prevent.
So how do I keep my horse cool in summer?
1. Water, water, everywhere!
Often, people believe the old wives’ tale that they should not allow a hot horse to drink water; however water is essential to maintain adequate hydration status. Horses sweat to lose excess body heat; the heat of their body then evaporates this water, leaving their skin colder.
Excessive sweating without enough water to drink leads to dehydration, which can be very dangerous, causing a drop in blood pressure and an increased heart rate. Thus cool, clean water must be provided at all times, especially in outdoor grazers, to ensure they can replenish their hydration states.
