Why Is My Horse Itchy in Autumn and Winter? Causes, Care & How to Soothe Irritated Skin

When we think about an itchy horse, our minds often jump straight to spring and summer. Midges, flies, warm weather and sweet itch are obvious culprits, and many horse owners breathe a sigh of relief when autumn finally arrives.

But what if your horse keeps scratching, rubbing or showing signs of itchy skin during autumn and winter?

At Amberley Aromatics, we know that itchy skin isn't necessarily just a summer problem. Some horses continue to rub their manes and tails well into autumn, while others actually seem to become itchier once the colder, wetter weather arrives.

Changes in temperature, wet weather, rugs, thicker winter coats, mud and changes in management can all affect the skin.

So, if you're wondering "Why is my horse so itchy in winter?", here are some of the things worth considering.

1. The Change From Summer to Autumn

Autumn is a significant period of change for horses.

Days become shorter, temperatures fluctuate and horses begin growing their thicker winter coats. At the same time, many horses are spending more time rugged or stabled.

For a horse with sensitive skin, that's quite a lot of change in a relatively short period.

Don't assume that summer skin irritation will disappear as soon as September arrives either. Depending on weather conditions, biting insects and midges can remain active surprisingly late into the year.

Warm, damp autumn weather can mean that horses prone to seasonal itching continue rubbing their mane, tail and body long after we expect the traditional "sweet itch season" to have finished.

2. A Thick Winter Coat Can Make Skin Problems Harder to Spot

One of the difficulties with winter skin care is simply being able to see what's going on underneath all that hair.

A thick winter coat can hide:

• Dry or flaky skin
• Scurf
• Small areas of irritation
• Crusty or broken skin
• Hair loss
• Lumps and bumps
• Parasites
• Early signs of infection

Regular grooming isn't just about keeping your horse looking smart. It's also an opportunity to get your hands onto the skin and notice changes before they develop into something more troublesome.

Part the coat and have a proper look, particularly if your horse suddenly enjoys being scratched much more than usual or starts rubbing against stable doors, fences, posts or trees.

3. Rugs Can Contribute to Itchy Skin

Rugs are another common factor worth considering.

During autumn, temperatures can change enormously between day and night. A horse that needs a rug during a cold night can become surprisingly warm underneath it when the sun appears the following afternoon.

Sweat, warmth and friction underneath rugs can make already-sensitive skin feel uncomfortable.

Dirty rugs can also accumulate sweat, grease, dust and debris.

Pay particular attention to areas where rugs can rub, including:

• The shoulders
• Withers
• Chest
• Mane
• Base of the neck
• Along the spine

Take rugs off regularly and have a good look and feel underneath.

And don't automatically assume that a horse needs a heavier rug simply because the calendar says winter!

4. Dry Winter Skin

While autumn can be wet and humid, winter brings another potential problem: dry skin.

Cold weather, wind, central heating in enclosed environments, repeated washing and changes in the natural oils within the coat can all contribute to skin becoming dry or flaky.

Over-washing can sometimes make matters worse.

A horse's skin produces natural oils that help maintain the condition of both skin and coat. Constant shampooing with harsh detergents can strip these oils away.

If you do need to shampoo an itchy or sensitive horse, look for a gentle, low-lather formulation that cleans without excessively stripping the coat.

Our Amberley Aromatics Itchy Horse Shampoo uses an organic Aloe Vera shampoo base alongside carefully selected essential oils. It is designed to cleanse gently while leaving the coat beautifully soft and shiny.

5. Mud and Wet Conditions

For many UK horse owners, autumn and winter mean one thing:

Mud. Lots of it.

Continually wet skin can become softened and more vulnerable to irritation, particularly around the lower legs.

Repeated cycles of wet → dry → wet → dry can also compromise the skin's natural protective barrier.

Try not to think about winter skin care only when you can already see a problem.

Regularly checking the legs, heels and pasterns means you're much more likely to notice subtle changes early.

Where possible, allowing wet legs to dry naturally before gently removing dried mud can also avoid unnecessary repeated washing.

6. Lice and Other Parasites

If your horse suddenly becomes extremely itchy during winter, parasites should always be considered.

Lice can be particularly troublesome during the colder months and can thrive within a thick winter coat.

You may notice your horse:

• Rubbing against fences or stable walls
• Biting at their sides
• Becoming restless when rugged
• Developing areas of hair loss
• Having a dull or scurfy coat
• Becoming unusually enthusiastic about being scratched

Some horses may have significant irritation before parasites are immediately obvious.

If you suspect lice, mites or another parasitic problem, speak to your vet for appropriate diagnosis and treatment rather than relying on cosmetic skin products alone.

7. The Itch–Scratch Cycle

One of the biggest problems with itchy skin is that scratching itself can create more irritation.

• The horse feels itchy.
• They rub.
• The rubbing irritates or damages the skin.
• The irritated skin feels even itchier.
• So they rub again.

Before long, a relatively minor irritation can result in broken hairs, bald areas, damaged mane or tail hair and sore-looking skin.

This is why it's useful to investigate new rubbing behaviour early rather than waiting until your horse has removed half their mane!

How Can I Help My Itchy Horse During Autumn and Winter?

Start with observation.

Think about what has changed.

Has your horse recently started wearing a rug?

Have you changed washing powder, grooming products or bedding?

Have they grown a particularly thick winter coat?

Are they sweating underneath their rug?

Has the weather suddenly become wetter?

Are they rubbing one particular area or itching all over?

Are other horses on the yard itchy too?

Sometimes the pattern gives you important clues.

Keep the Skin and Coat Clean — But Don't Over-Wash

Regular grooming helps remove loose hair, dead skin and dirt while allowing you to monitor your horse's skin.

When shampooing is needed, choose something gentle.

Avoid assuming that more shampoo, more foam or more frequent washing means cleaner or healthier skin.

A gentle product that rinses away easily is often far more appropriate for sensitive horses.

Don't Forget Moisture

Dry, tight-feeling skin needs a different approach from simply cleaning it.

This is where a soothing gel can be particularly useful.

Our Itchy Horse Gel is the garlic-free member of the Amberley Itchy Horse range and is particularly popular outside the main fly season.

Its Aloe Vera base is combined with cold-pressed Neem and a carefully selected blend of essential oils to help condition and soothe the skin.

For horses that don't need the additional garlic found in our spring and summer PLUS formulations, it provides a lovely autumn and winter alternative.

Check Your Rugs

Remove rugs every day whenever possible.

Run your hands over your horse and look for heat, sweat, scurf, lumps, rubbed hair or areas where your horse reacts when touched.

Keep rugs clean and make sure they fit correctly.

Sometimes solving an apparently mysterious winter itch can be as simple as realising that your horse is simply too hot.

When Should I Call My Vet?

Not every itchy horse has a simple skincare problem.

Persistent or severe itching can have numerous causes, including parasites, allergies, infections and other underlying health issues.

Contact your vet if your horse has severe or unexplained itching, significant hair loss, swelling, painful skin, weeping or infected-looking areas, widespread crusting, a sudden deterioration or is generally unwell.

It's particularly important to seek professional advice when the cause isn't clear or when sensible changes to management aren't helping.

Skincare products can support the condition and comfort of the skin, but they shouldn't be used as a substitute for veterinary diagnosis when something more significant may be going on.

Autumn and Winter Skin Care: Prevention Is Better Than Waiting for a Problem

Perhaps the biggest lesson we've learned from working with itchy horses over the years is that skin care shouldn't stop when summer ends.

Autumn and winter bring their own challenges.

Thick coats, rugs, mud, rain, sweat, cold weather and changes in management all influence the environment surrounding your horse's skin.

A simple routine can make a big difference:

• Regular grooming.
• Regular skin checks.
• Clean, correctly fitted rugs.
• Avoiding unnecessary over-rugging.
• Gentle cleansing when required.
• Supporting dry or sensitive skin.
• And investigating unexplained itching rather than simply accepting it as "something they do".

Your horse's coat might get considerably fluffier during the colder months, but healthy skin underneath it is just as important all year round.

Frequently Asked Questions

Why is my horse itchy in winter?

Winter itching can have many possible causes, including dry skin, sweating beneath rugs, friction, dirty rugs, parasites such as lice or mites, thick coats concealing skin problems and underlying skin conditions. Persistent or severe itching should be investigated by your vet.

Can horses still have sweet itch in autumn?

Yes. Sweet itch is associated with a reaction to bites from Culicoides midges, and midge activity doesn't necessarily stop as soon as summer ends. During mild autumn weather, susceptible horses may continue to experience problems.

Should I shampoo an itchy horse?

Sometimes gentle cleansing can be useful, particularly when sweat, dirt or product build-up is present. However, excessive washing or harsh shampoos may remove the skin and coat's natural oils. Choose a gentle shampoo and avoid unnecessary over-washing.

Why does my horse itch when wearing a rug?

The horse may be too warm, sweating, experiencing friction from the rug, reacting to accumulated dirt or simply have an unrelated skin problem hidden underneath it. Remove rugs regularly and inspect the skin and coat carefully.

What can I put on my horse's dry, itchy skin?

The right approach depends on why the horse is itchy. For uncomplicated dry or sensitive skin, gentle cleansing and soothing, moisturising skincare may help maintain the skin's condition. Persistent, severe, broken or infected-looking skin needs veterinary attention.
