Overview
If your horse has scabs and hair loss from rubbing, call the vet if the skin is hot, swollen, painful, oozing, spreading, or if your horse is very distressed. If it’s a mild patch and your horse is otherwise well, it’s reasonable to check for common triggers first, but keep a close eye on it because rubbing can quickly make skin problems worse.
Things To Check
1. Note where the rubbing is happening, such as the mane, tail, face, sheath, girth area or around the ears.
2. Check whether the skin looks red, sore, broken, crusted, greasy, or covered with scabs.
3. See if there’s any heat, swelling, discharge, a bad smell, or signs of discomfort when you touch the area.
4. Think about timing, including whether it started after turnout, in hot weather, after grooming, or when flies are active.
5. Look for signs of itchiness elsewhere, such as tail rubbing, stamping, head shaking, or general restlessness.
6. Check for possible irritants, including sweat, mud, dirty rugs, tack rubbing, new grooming products, or a change in feed or bedding.
7. Make a note of whether the problem is spreading, staying the same, or improving over a few days.
Common Causes
The most common causes are insect irritation, sweet itch type rubbing, and skin irritation from sweat, dirt, or friction. Horses can also rub from tack, rugs, grooming, or a reaction to something in the environment.
Less commonly, scabs and hair loss may be linked to skin infection, mites, lice, fungal problems, or an underlying allergy that needs proper assessment.
What To Do
Keep the area clean and dry, and avoid anything that seems to make the rubbing worse. Check rugs, tack, and grooming habits for rubbing points, and remove obvious irritants where you can.
If the skin is mildly sore, keep handling gentle and avoid picking scabs. Take a photo each day so you can see whether it is getting better or worse. If flies seem to be a trigger, try to reduce exposure as part of your normal management.
Call your vet if the skin is becoming more inflamed, the rubbing is intense, there is discharge or swelling, or the problem is not improving after a short period of sensible home checks.
When To Contact A Vet
Contact your vet promptly if the area is hot, painful, swollen, weeping, foul-smelling, or rapidly spreading, or if your horse seems unwell. You should also call if the rubbing is severe, keeps coming back, or you suspect infection, mites, lice, or an allergic skin problem that needs diagnosis.
Products That May Help
If the rubbing seems worse in fly season or after turnout, a summer care routine may help support day-to-day management while you keep an eye on the skin.
