Overview
Crusty lesions around the saddle area can happen for a few reasons, and ringworm is one possible cause. It can also be down to rubbing from tack, sweat irritation, mud, or another skin issue, so it’s worth checking the area closely rather than assuming it’s one thing straight away.
If the horse is otherwise well, the main job is to look at the pattern of the skin changes, think about recent tack use and grooming, and monitor whether the spots are spreading or getting more inflamed.
Things To Check
1. See whether the crusty areas are under the saddle panels, near the girth, or where tack has been rubbing most.
2. Check if the skin is circular, patchy, scabby, or broken, as ringworm often looks different from simple rubbing.
3. Look for hair loss, dandruff-like flakes, redness, or a slightly raised edge around the lesions.
4. Feel gently around the area for heat, soreness, or swelling.
5. Think about whether the horse has been sweaty, clipped, turned out in wet weather, or wearing tack for longer than usual.
6. Check saddle fit, numnah cleanliness, and whether any new grooming products or washing routines were started recently.
7. Look at other horses or other parts of your own horse’s body to see if similar patches are appearing elsewhere.
Common Causes
Ringworm is one common cause of crusty, patchy skin lesions and often shows up as round areas of hair loss or scabbing. It can spread between horses, so it’s worth keeping in mind if the pattern fits.
Rubbing from the saddle, girth or numnah can also leave crusty, irritated skin, especially if tack doesn’t fit well, the area is sweaty, or dirt has been trapped against the coat.
Less commonly, the skin may be reacting to sweat, grooming products, mud, or another skin infection that needs a closer look.
What To Do
Until you know what’s going on, avoid putting tack directly on the sore area if you can, and keep the skin as clean and dry as practical. Gentle grooming around the patch is usually better than scrubbing it.
Wash hands after handling the area, and avoid sharing brushes, rugs or tack if ringworm is a possibility. If the horse is sweaty after exercise, let the skin dry properly before tacking up again.
Make a note of whether the lesions are staying the same, improving, or spreading. If they’re not settling or the horse seems sore, getting a vet’s opinion is sensible.
When To Contact A Vet
Contact your vet if the lesions are spreading, the horse seems uncomfortable, the skin is very inflamed or painful, or several horses in the same yard are developing similar patches. Ringworm and other skin problems can look alike, and a vet can help confirm what’s going on and advise on the best management.
Products That May Help
If you’re dealing with crusty skin around the saddle area, a gentle wash routine can sometimes be useful as part of everyday coat care and hygiene while you keep an eye on the area.
