Why does my horse have scabs on its lower legs?

Overview
Scabs on the lower legs are often seen with mud fever, especially if your horse has been standing in wet, muddy conditions. They can also happen with simple skin irritation, small knocks, or other skin problems, so it’s worth checking the area carefully rather than assuming it’s just mud.
Things To Check
1. Check whether the scabs are on the heels, fetlocks or back of the pasterns, where mud often sits.
2. Look for redness, heat, swelling, soreness or broken skin around the scabs.
3. Note whether the legs are wet or muddy for long periods after turnout.
4. Check if the horse objects when you touch, wash or brush the area.
5. Look for hair loss, crusting, discharge or any smell from the skin.
6. Consider whether the problem started after clipping, washing, boot use or a change in turnout.
7. Check the other legs too, since this can help you spot a pattern rather than a one-off knock.
Common Causes
The most common cause is mud fever, which is often linked to wet, muddy ground and skin that stays damp for too long. The skin can become irritated, scabby and sore.
Other common causes include mild dermatitis from moisture, dirt or friction, plus small scrapes or knocks that then crust over as they heal.
Less commonly, lower leg scabs can be part of a more widespread skin issue, such as a reaction to grooming products, mites, or another skin condition that needs proper assessment.
What To Do
Keep the area clean and dry, and avoid picking scabs off, as that can make the skin more sore and delay healing.
If the leg is muddy, soften and lift dirt gently rather than scrubbing hard. Dry the area carefully afterwards and keep an eye on whether new scabs are forming.
Try to reduce how long the horse spends standing in wet, muddy conditions where possible, and check turnout rugs or boots for rubbing or trapped moisture.
If the problem keeps coming back, make a note of when it appears, what the weather has been like and whether the horse has been washed, clipped or booted recently. That pattern can be very helpful.
