WHY YOUR HORSE MAY BE MORE REACTIVE IN SUMMER
Hot, sweaty, covered in flies… and you want me to concentrate?!
We talk a lot about horses having less energy in the heat—but here's the funny part:
●A horse can feel physically sluggish and STILL be mentally more reactive.
You may notice your normally quiet horse suddenly:
■ Swishing their tail nonstop
■ Getting irritated while being groomed or saddled
■Tossing their head or shaking
■ Overreacting to a fly landing on them
■Jumping at something they'd normally ignore
■ Having approximately ZERO patience for your plans
And before we decide they're suddenly being "bad," think about their environment.
Imagine trying to concentrate while you're hot, sweaty, uncomfortable and someone keeps poking you every 3 seconds.
Congratulations. You're now a horse during fly season.
》Flies can create sensory overload.
A horse may spend hours twitching their skin, stomping, swishing, shaking and moving away from insects.
Add heat and humidity, tack, physical work and rider expectations…
…and their tolerance may be considerably lower than it would be on a comfortable 65° day.
》 Heat can change the whole picture, too.
Physical discomfort and fatigue can affect how willing a horse is to stand quietly, focus and respond patiently.
That doesn't mean every unwanted behavior should be excused because "it's hot."
It means good horsemanship asks:
WHY is my horse behaving differently today?
Before increasing pressure, look at the entire situation.
●Could they be hot?
●Are flies terrible?
●Is their tack rubbing sweaty skin?
●Are they tired?
●Is something physically uncomfortable?
●Is today's environment simply asking more from them?
Sometimes your horse doesn't need a bigger correction.
They need you to recognize that their cup is already pretty full.
Training isn't about pretending expectations don't exist.
It's learning when to push, when to teach, when to adjust—and when your horse is telling you:
“Ma'am. A fly has landed on my eyeball for the 47th time. Today is NOT the day.”
