Overview
A dark spot under your horse’s hoof is often a bruise, but it can also be simple staining, trapped dirt, or a change in the hoof capsule or sole. In many cases it’s minor, but it’s worth checking carefully so you can spot anything that needs attention.
Things To Check
1. Look at when you first noticed the dark area and whether it changes after turnout, exercise, or cleaning.
2. Check for heat in the hoof, a stronger-than-usual pulse, or any signs your horse is uncomfortable on that foot.
3. Pick out the hoof and see whether the spot is just dirt or whether it looks deeper, like a mark in the sole or frog.
4. Look for cracks, soreness, discharge, bad smell, loose horn, or any damaged area around the spot.
5. Compare the hoof with the others to see if the shape, colour, wear, or condition is different.
6. Think about recent hard ground, stones, a knock, new turnout conditions, or a shoeing change.
7. Watch how your horse walks and turns, especially on firmer ground or circles.
Common Causes
A hoof bruise is one of the most common reasons for a dark spot, especially after hard going, a knock, or extra pressure on the foot. These can look like a patch of darker sole or horn.
Sometimes it’s just dirt, staining, or debris caught in the grooves of the frog or around the white line, which can look more concerning than it is at first glance.
A small area of old damage, worn horn, or minor separation in the hoof can also appear darker.
Less commonly, a darker area can be linked with deeper hoof issues, especially if there’s pain, heat, a pulse, smell, or discharge alongside it.
What To Do
Clean the hoof carefully and keep an eye on whether the dark area changes over a few days. Take a clear photo so you can compare it later.
Check the footing your horse is on and reduce exposure to very hard, stony, or very wet and muddy ground where possible.
Keep up regular picking out and routine hoof care, and make sure the horse is being shod or trimmed on schedule.
If your horse seems sore, rest may be sensible until you’ve had the hoof checked. If the area stays the same but doesn’t look or feel right, ask your farrier or vet for advice.
