Overview
Thick, wet, painful scabs on a horse are often seen with rain scald, especially after prolonged wet weather, but other skin problems can look similar. The scabs may feel glued to the coat because the skin underneath is irritated, damp or inflamed, so removing them can be sore and may make the area worse.
It’s usually best not to pick scabs off forcefully. Instead, check the skin carefully, keep the area clean and dry where possible, and watch for signs that the problem is spreading or not settling.
Things To Check
1. Check whether the scabs are on the back, topline, neck, rump or other areas that get wet during turnout.
2. Look for dampness under the coat, rain exposure, mud, sweating under rugs or repeated wetting after exercise.
3. Notice whether the skin under the scabs is red, sore, swollen or warm to touch.
4. See if the scabs lift easily or if they are firmly stuck and leave raw skin underneath when disturbed.
5. Check for patchy hair loss, flaky skin, discharge, an unpleasant smell or crusting in several areas.
6. Consider whether your horse has been clipped, rugged heavily, or is spending more time in wet, muddy conditions than usual.
7. Watch for rubbing, sensitivity when grooming, or clear discomfort when you touch the area.
Common Causes
Rain scald is a common cause, especially when a horse’s coat stays damp for long periods. The skin can become irritated, and the scabs may feel wet or sticky underneath.
Other skin infections or irritation from mud, sweat, rugs or grooming can sometimes look similar. In some horses, bacteria or mixed skin irritation may be involved, particularly if the skin barrier has already been damaged.
Less commonly, parasites, allergy-related skin issues or other skin conditions can cause crusting and soreness. These can’t be ruled out just by looking, especially if the problem keeps coming back.
What To Do
Try not to pull the scabs off dry, as that can make the skin more painful and slow down settling. If you do wash the area, use lukewarm water and be very gentle, then dry the coat thoroughly afterwards.
Keep turnout and rugging as dry and clean as you reasonably can. If the horse is getting repeatedly wet, changing the routine to reduce prolonged dampness may help support recovery.
Monitor the area daily for spreading patches, increasing soreness or new discharge. If the scabs are returning often, note when they appear, where they are and what the weather or turnout conditions were like.
When To Contact A Vet
Speak to your vet if the skin is very painful, the sores are spreading, there’s marked swelling or discharge, or your horse seems unwell. It’s also sensible to ask for advice if the problem keeps coming back, isn’t improving with careful management, or you’re not sure whether something else could be going on.
