Why is my horse itchy under the mane and along the tail?

Read time: 3 minutes

Overview

Itching under the mane and along the tail can happen with lice, but it can also be caused by flies, skin irritation, allergies, mud, or rubbing from tack and rugs. Lice are a common cause, especially in colder months or when horses are in close contact, but you can't tell for certain without checking the coat and skin closely.

Things To Check

1. Check whether the itching is worse after grooming, turnout, rugging, or exercise.

2. Look closely for tiny moving insects, white eggs attached to hairs, scabs, broken hairs, or areas of rough coat.

3. Feel for heat, swelling, or sore patches under the mane and at the tail head.

4. Check whether other horses in the same stable or field are also rubbing or scratching.

5. Look for signs of rubbing from rugs, tack, or dirty or damp bedding.

6. Notice whether the problem is seasonal, as some horses itch more during fly season.

7. Check the skin for dandruff, dry flakes, redness, or areas where the hair has been rubbed thin.

Common Causes

Lice are a common reason for itching under the mane, tail, and sometimes the face or legs. Horses may rub, bite at the skin, and develop a rough coat or scabs.

Fly irritation or sweet itch can also cause tail rubbing, mane rubbing, and stamping, especially during warmer months.

Skin irritation from mud, sweat, grooming friction, dirty rugs, or tack can make these areas sore and itchy.

Allergic or inflammatory skin problems may also play a part if the itching keeps returning or affects several areas of the body.

What To Do

Start by parting the mane and tail hairs to look for skin changes, debris, or signs of parasites. If you can, check other horses that have been in close contact, because lice can spread between animals sharing space or equipment.

Keep the coat clean and dry, and make sure rugs, tack, grooming kit, and stable surroundings are kept as clean as possible. Avoid over-grooming the irritated skin, as that can make the problem worse.

Keep a simple note of when the itching happens, what the skin looks like, and whether it is getting better or worse. That makes it easier to spot patterns and explain the issue if you do need advice.

If the horse is rubbing hard enough to damage the skin, if several horses are affected, or if you spot obvious parasites, it is sensible to ask your vet for guidance on the next step.
