Overview
If your horse’s muzzle is peeling or crusting after hot weather, sunburn is one common reason, especially on pale or pink skin. It can also happen with rubbing, irritation from sweat or mud, or a mild skin reaction, so it’s worth checking the area closely rather than assuming it’s just the sun.
Things To Check
1. Check whether the peeling started after a spell of strong sun, turnout, or riding in hot weather.
2. Look closely for redness, scabs, crusts, broken skin, swelling or any damp discharge.
3. See whether the muzzle is sore when touched, or whether your horse is rubbing it on fences, rugs or stable surfaces.
4. Check if the skin is mainly affected on pale, pink or lightly pigmented areas, which can be more prone to sun-related irritation.
5. Note whether there’s also itching, head shaking, sneezing or sensitivity around the nostrils.
6. Think about whether new feed, grooming products, fly sprays or cleaners may have come into contact with the area.
7. Check the rest of the face and body for similar patches, which may suggest a wider skin issue rather than one localised spot.
Common Causes
Sunburn is a frequent cause, particularly on pink or lightly pigmented muzzle skin. The area may look dry, flaky or crusted after hot, sunny weather.
Irritation from sweat, dust or rubbing can also leave the muzzle sore and peeling, especially if tack, masks or turnout conditions have caused repeated friction.
Mild skin reactions to products, plants or environmental contact can sometimes cause crusting or peeling too.
Less commonly, a skin infection or another skin condition may be involved, particularly if the area is getting worse, spreading or becoming more painful.
What To Do
Keep the area clean and dry, and avoid scrubbing the muzzle as that can make the skin more irritated.
If your horse is going back out in strong sun, think about shade, turnout timing and reducing exposure where you can. A well-fitting, practical sun barrier for the face may be useful if your horse is prone to pale-skin flare-ups, but choose one that suits your horse and check it doesn’t rub.
Watch the area for 24 to 48 hours so you can see whether it is improving, staying the same or getting worse. If you’ve changed grooming products, feed or turnout setup recently, it’s worth considering whether anything new may be irritating the skin.
If the muzzle becomes more painful, spreads, oozes, or doesn’t start to settle, get veterinary advice.
Products That May Help
A gentle washing routine can be useful if your horse’s muzzle has picked up sweat, dust or residue after hot weather, especially when the skin is already sensitive.
