Overview
Round scabby patches on a foal are often consistent with ringworm, but they can also be caused by other skin irritations or infections. It’s sensible to check the patches closely and monitor whether they’re spreading, itchy, or affecting other horses in the yard.
Things To Check
1. Look at the shape of the patches. Ringworm often shows as round, greyish or scabby patches with hair loss.
2. Check whether the skin feels dry, crusty, warm, or sore to the touch.
3. Notice if the foal is rubbing, scratching, or showing any irritation.
4. See whether there are similar patches on the face, neck, girth area, legs, or other horses nearby.
5. Think about any recent changes such as new bedding, turnout, grooming tools, rugs, or contact with other young horses.
6. Check whether the patches are spreading, multiplying, or becoming more inflamed over a few days.
7. Look for any discharge, swelling, broken skin, or signs the foal seems unwell.
Common Causes
The most common cause is ringworm, which is a fungal skin infection and often appears as round, scabby patches with hair loss.
Other possibilities include simple skin irritation from rubbing, minor trauma, or less commonly a bacterial skin issue, especially if the skin is damaged or wet.
In young horses, management factors such as dirty grooming equipment, shared brushes, damp tack areas, or close contact with other affected horses can also make skin problems more noticeable.
What To Do
Keep the area clean and dry, and avoid picking at the scabs. Use separate grooming equipment for the foal if possible, and wash your hands after handling the patches.
Try to prevent the foal from sharing brushes, cloths, or rugs with other horses until you know what’s going on. If practical, keep an eye on any other horses for similar signs.
Take a few clear photos so you can compare the patches over time. If the skin is spreading, not improving, or you’re unsure what you’re seeing, a vet can advise on the most appropriate next step.
