Overview
If you think your horse may have ringworm, it’s sensible to call a vet if the area is spreading, looks very sore, isn’t improving, or you’re not sure it really is ringworm. Many skin problems can look similar, so a vet can help confirm what’s going on and advise on the best next step.
Some mild cases can be managed with careful hygiene and monitoring, but ringworm is contagious and can spread to other horses, people and tack or grooming kit. That’s why getting the right advice early can be useful.
Things To Check
1. Check whether the patch is getting bigger or new areas are appearing on the face, neck, girth area or legs.
2. Look for round patches of hair loss, scurf, crusting, scabs or broken hairs, which are commonly seen with ringworm.
3. Note whether the skin is very itchy, hot, painful or swollen, as that can point to irritation or another skin issue.
4. Check if any other horses, people, or animals on the yard have similar patches.
5. Think about whether there’s been recent sharing of grooming brushes, saddle pads, rugs or tack between horses.
6. Watch for discharge, cracking skin or a strong smell, which may suggest the area needs closer attention.
7. Consider whether your horse has recently been wet, clipped, stressed or in a new environment, as these can sometimes go along with skin flare-ups.
Common Causes
Ringworm is often the first thing owners think of when they see circular hair loss and scaly patches, but it’s not the only cause.
Other common possibilities include skin irritation from rubbing, reactions to rugs or tack, mud-related skin problems, insect bites, or minor bacterial skin infection.
Less commonly, a vet may need to rule out mange, allergy-related skin disease or other causes of coat and skin damage.
What To Do
Keep a close eye on the area and take a photo every few days so you can tell whether it’s changing.
Avoid sharing grooming kit, rugs, headcollars or tack between horses until you know what you’re dealing with.
Wash hands after handling the affected area and clean any kit that may have come into contact with it, following normal yard hygiene routines.
Try not to pick at scabs or scrub the skin harshly, as that can make the area more irritated.
If your horse is comfortable, a gentle wash with an appropriate coat-care product may help keep the skin clean as part of your routine, but avoid using anything too harsh without advice if the skin is broken or very sore.
When To Contact A Vet
Contact your vet if the patch is spreading, your horse seems uncomfortable, the skin is weeping or very inflamed, or you’re unsure whether it’s ringworm at all. It’s also worth calling if the problem is affecting more than one horse on the yard, because it may need a clearer plan for isolation and hygiene.
Products That May Help
Keeping the coat and skin clean can be useful as part of your normal hygiene routine while you’re monitoring a suspected skin problem.
