Overview
If your horse’s muzzle is pale, flaky and sore, sun exposure is one of the first things to consider, especially in horses with pink skin. It can also happen with irritation from rubbing, insect exposure, or a skin issue that needs a closer look, so it’s worth checking the area carefully rather than assuming it’s just sunburn.
Things To Check
1. Check whether the muzzle has been in strong sun, especially around turnout, midday exercise or long periods without shade.
2. Look closely for redness, peeling, crusts, scabs, broken skin, swelling or any discharge.
3. Feel gently for heat or tenderness, and note whether your horse pulls away when you touch the area.
4. Check if the soreness is limited to the muzzle or whether there are similar changes on other pink areas such as the face or around the eyes.
5. Think about any recent changes in turnout, grooming, feeds, masks, nose covers or contact with plants, mud or equipment.
6. Look for rubbing or scratching, as repeated friction can make the skin look flaky and sore.
7. Watch whether your horse is eating, drinking and behaving normally, since discomfort can sometimes affect routine.
Common Causes
The most common cause is mild sunburn on pale or unpigmented skin, which can leave the muzzle dry, flaky and sore. Irritation from rubbing, flies or contact with something on the skin can also make the area look similar. Less commonly, a skin infection, allergy or another skin condition may be involved, especially if there is swelling, spreading redness or discharge.
What To Do
Move your horse out of strong sun where you can, and keep an eye on whether the muzzle improves over the next day or two. Avoid picking at flakes or scabs, and use only gentle handling when cleaning or grooming the area. If something has recently changed in turnout, tack, face gear or grooming routine, think about whether that could be irritating the skin and adjust it if needed. Take a couple of photos so you can compare any change over time.
