Overview
If your horse has thrush in multiple hooves, the first step is to improve hoof hygiene and check the environment. It often happens when hooves are staying damp, dirty or packed with soiled bedding, but there can be more than one reason, so it’s worth looking at the full picture.
Multiple hooves being affected usually suggests a management issue rather than a one-off problem in a single foot. You can often make a good start at home, but if there’s lameness, heat, swelling or the horse seems sore, a vet should be involved.
Things To Check
1. Check whether the smell, black discharge or soft frog tissue is present in one hoof or several.
2. Look at the stable, turnout and bedding for wet patches, heavy mucking-up or areas where the hooves are standing in damp conditions.
3. Check the frog and the grooves either side of it for deep cracks, retained dirt or obvious soreness.
4. Feel each hoof for warmth and notice whether your horse is more footsore than usual on hard ground.
5. Watch how your horse moves on turns, when picking up each foot and when walking out of the stable.
6. Check whether the issue is worse after turnout, after wet weather or after time on dirty bedding.
7. Look for other signs of poor hoof condition such as crumbly hoof wall, muddy heels or a runny, dirty lower leg.
Common Causes
The most common cause is a damp, dirty environment. Thrush tends to thrive when hooves are left in wet bedding, muddy fields or manure-contaminated areas for long periods.
Poor hoof hygiene can also play a part, especially if the feet are not picked out regularly or mud is building up around the frog.
Less commonly, repeated thrush in several hooves can be linked to deeper hoof balance issues, low heel support, or a horse that is struggling to stay dry because of turnout or stable conditions.
What To Do
Pick out all feet carefully every day, and more often if the horse is in wet or muddy conditions. Remove packed dirt, straw and manure gently so you can see what’s going on.
Improve the horse’s environment where you can. Keep bedding as dry as possible, skip out wet patches promptly and try to reduce time standing in mud or soiled areas.
After cleaning, keep an eye on the frogs and heel area over the next few days. You’re looking for less smell, less discharge and improved comfort rather than expecting an instant change.
If several hooves are affected at once, it’s sensible to review turnout, stable cleaning and daily hoof care as a whole routine rather than focusing on just one foot.
