Overview
If your horse is rubbing or stamping and the lower legs are crusty, it often means the skin there is irritated. Common causes include mud, sweat, dirt build-up, dry skin, minor irritation and conditions such as mallenders and sallenders. You can usually check a few simple things at home, but crusting that keeps coming back, spreads, or becomes sore should be looked at by a vet.
Things To Check
1. Check whether the rubbing or stamping happens after turnout, exercise, clipping, grooming or washing.
2. Look closely at the lower legs for scabs, crusts, redness, heat, swelling, broken skin or discharge.
3. Feel whether the area seems dry, sore or thickened, especially around the back of the knees or hocks and down the back of the legs.
4. Consider whether muddy fields, wet bedding, sweat or repeated washing could be making the skin worse.
5. Check if the horse is rubbing only one leg or several, as that can give a clue about a local irritant or a wider skin issue.
6. Look for signs of insects, mites or other skin irritation, especially if the horse seems more itchy in warmer weather.
7. Note whether the horse seems uncomfortable when the crusty areas are touched or cleaned.
Common Causes
Mud, sweat and dirt can irritate the skin on the lower legs, especially if the area stays damp or is not dried properly after washing or turnout.
Dry, flaky skin can also make a horse stamp or rub, particularly if grooming is a bit harsh or the coat and skin are already sensitive.
Mallenders and sallenders are a common reason for crusty, scabby skin on the lower legs. These are usually seen as thickened, crusty or scaly patches and can be uncomfortable.
Insect irritation, mites or other skin sensitivities can sometimes look similar, especially if the horse is itchy in more than one area.
What To Do
Keep a note of when the rubbing or stamping happens and what the skin looks like each day. That helps you spot patterns and see whether things are improving or getting worse.
Gently clean the area only as much as needed, then dry it carefully. Avoid scrubbing crusts off, as that can make the skin more sore.
Try to reduce prolonged dampness, deep mud and repeated irritation where you can. Keeping the legs clean and dry is often the most practical place to start.
Use calm, consistent grooming and avoid anything that seems to make the skin more uncomfortable. If the horse is very sore, avoid picking at the crusts.
If the issue keeps returning, is spreading, or the horse is becoming more uncomfortable, arrange a vet check so the cause can be properly assessed.
