Overview
If your horse’s muzzle looks mildly pink or dry after sun exposure, you can often keep a close eye on it at home. Call the vet if the skin is blistered, very painful, swollen, cracked and bleeding, covered in discharge or scabs, or if your horse seems unwell. It’s also sensible to ask for advice if the area isn’t improving after a couple of days or keeps getting worse.
Things To Check
1. Check whether the soreness appeared after turnout in bright sun, especially if the muzzle is pale or pink-skinned.
2. Look closely for redness, raw patches, broken skin, scabs, crusting, swelling or discharge.
3. See whether your horse is rubbing the muzzle on fences, rugs, haynets or stable surfaces.
4. Notice if your horse is sensitive when you touch the area, eat, drink or put on a nose cover.
5. Check whether there are other signs too, such as eye irritation, facial swelling or general discomfort.
6. Think about whether there could be another cause, such as a minor scrape, insect irritation or contact with something harsh.
7. Monitor whether the skin is improving, staying the same or getting worse over 24 to 48 hours.
Common Causes
The most common cause is simple sun exposure on a pale or unpigmented muzzle. This can leave the skin pink, sore and dry.
Sometimes the same area is rubbed or irritated by a nose net, grazing muzzle, tack or repeated contact with fencing and feed tubs.
Less commonly, what looks like sunburn may be a minor skin injury, an allergic reaction, or a skin problem that needs veterinary assessment if it doesn’t settle.
What To Do
Move your horse out of strong sun where possible and keep an eye on the area for changes.
Use a calm, gentle approach when handling the muzzle, and avoid anything that seems to make the skin more sore.
Check turnout management, shade and any nose coverings that may be rubbing.
If the skin is only mildly affected, monitor it closely and keep the area clean and dry without scrubbing.
Products That May Help
