Why does my horse seem more restless in the field during summer?

Read time: 3 minutes

Overview

If your horse seems more restless in the field during summer, flies and midges are a very common reason. Heat, sweating, grazing discomfort and general seasonal irritation can also make some horses harder to settle.

Often the pattern is the clue. If the restlessness starts in warm weather, near water, at dusk, or when insects are most active, fly and midge irritation is a likely factor. But there can be several causes, so it’s worth checking the basics before assuming it’s just the season.

Things To Check

1. Notice when the behaviour starts, such as at certain times of day, after turnout, or when the horse is standing still.

2. Look for signs of irritation, including tail swishing, stamping, skin twitching, head tossing, rubbing or repeated moving about.

3. Check for visible skin changes such as small bumps, raised areas, scabs, redness or broken skin, especially around the mane, tail, belly and lower legs.

4. See whether the horse is sweating more than usual or standing in direct sun with limited shade or airflow.

5. Check the field for obvious fly hotspots, such as standing water, muck heaps, wet gateways or areas where insects seem worse.

6. Notice whether the horse is restless only in one paddock, which can suggest the environment is a big part of the issue.

7. Check whether rugs, masks or other turnout kit are rubbing, slipping or making the horse look more uncomfortable.

Common Causes

Flies and midges are the most common cause of summer restlessness. Some horses are simply more sensitive than others, and even a modest insect burden can make them unsettled.

Heat and direct sun can add to the problem. A horse that feels hot, sweaty or bothered by sticky coat conditions may keep moving, standing awkwardly or not settling properly.

Skin irritation is another common reason. Bites, rubbing, damp skin or mild allergic-type sensitivity can make a horse more fidgety in the field.

Less commonly, field restlessness may be linked to other discomforts such as poor grazing access, boredom, herd tension or a kit fit issue. If the change is sudden or unusual for your horse, it’s worth keeping an open mind.

What To Do

Start by watching for a pattern over a few days. Note when the restlessness is worst, where the horse is standing and what the weather and insect levels are like.

Make the field as comfortable as you can. Shade, airflow, access to fresh water and avoiding the worst fly times can all help support a calmer routine.

Check that any fly rug, mask or turnout gear fits properly and isn’t creating extra rubbing or pressure. If it looks uncomfortable, pause and reassess before using it again.

Keep an eye on the skin and coat. If you spot bites, damp patches or rubbing, gentle routine care and good field hygiene may help reduce ongoing irritation.

If the behaviour is mild and clearly seasonal, it’s often sensible to manage it as part of your summer routine. If it’s getting worse, or you’re seeing skin damage, reduced grazing, marked distress or a sudden change in behaviour, ask your vet for advice.

Products That May Help

If flies and midges seem to be the main trigger, a summer care collection can be useful as part of your day-to-day management routine.
