Why is my horse rubbing its mane and mane base in summer?

Read time: 3 minutes

Overview

If your horse is rubbing its mane or mane base in summer, the most common reason is irritation from flies, midges or other insects. It can also happen if the skin is itchy from sweat, sun, dirty coat, tack rubbing or a skin problem, so it’s worth checking the area rather than assuming it’s just one thing.

Things To Check

1. Notice when the rubbing happens most. If it’s after turnout, at dusk, after sweating or during grooming, that can give a useful clue.

2. Part the mane and look at the skin along the mane base for redness, scabs, dandruff, broken hair, small wounds or areas that feel warmer than usual.

3. Check for insects around the neck, ears, poll and shoulders, especially if the horse is also stamping, tail swishing or head shaking.

4. Feel the area for knots, tangles or matted hair that could be making the skin sore when the horse moves or scratches.

5. Think about recent changes such as new turnout times, more sweating, a different rug, shampoo, feed or field conditions.

6. Look for signs of rubbing on other areas too, such as the tail, dock, face or belly, which can suggest a broader itch or fly irritation pattern.

7. Check whether the mane base is dry, greasy, dusty or full of pollen, as build-up can make an already irritated horse rub more.

Common Causes

Fly and midge irritation is one of the most common causes in summer, especially if the horse is sensitive to bites or spends time out at dawn and dusk.

Sweet itch or another insect-related skin allergy can also cause rubbing, often at the mane, tail head and withers. Some horses start with mild rubbing before the skin becomes broken.

Sweat, dirt and general skin irritation can make the mane base itchy after exercise or warm weather, particularly if the coat is not being kept clean and dry.

Tack or rug rubbing can sometimes affect the mane and neck area, especially if something has shifted, fitted tightly or become damp.

Less commonly, a skin infection, lice, mites or a reaction to a grooming product can play a part, so persistent rubbing is worth keeping an eye on.

What To Do

Start by checking the skin carefully and noting when the rubbing happens, how often it’s happening and whether there are any visible changes. That makes it easier to spot a pattern.

Keep the area as clean and comfortable as practical. Gentle grooming, removing sweat after work and checking the mane base for debris can help reduce avoidable irritation.

If insects seem to be the trigger, try to reduce exposure at the times they’re most active by adjusting turnout or stable routine where possible.

Make sure rugs, headcollars and tack sit comfortably and aren’t creating friction along the neck or mane line.

If the skin is broken, sore or worsening, don’t keep rubbing the area in the hope it will settle on its own. Monitor it closely and get advice if it’s not improving.
