Overview
Most mild cases of thrush can be managed with good daily hoof care, but you should call the vet if the smell is strong, the horse is lame, the frog looks very painful, or the problem isn't improving with regular cleaning. Thrush is often linked to wet, dirty conditions, but similar signs can sometimes happen with other hoof problems, so it’s worth keeping an eye on the bigger picture.
Things To Check
1. Check whether there’s a strong, rotten smell coming from the hoof, especially around the frog and central sulcus.
2. Look for black, soft, crumbly material, as well as any deep cracks or narrow splits in the frog.
3. Feel for heat in the hoof and note whether your horse is standing differently or seems sore on that foot.
4. Check if the hoof is being kept in wet bedding, muddy turnout, or dirty footing for long periods.
5. Look for swelling higher up the leg or signs the horse is more uncomfortable than you’d expect from a simple smell or discharge.
6. See whether cleaning the hoof is becoming difficult because the horse is pulling the foot away, flinching, or objecting to touch.
7. Check whether the problem is only in one hoof or whether it’s affecting several feet at once.
Common Causes
Thrush is most commonly linked to wet, dirty, or poorly drained conditions, especially if the hoof stays damp for long periods. Stabled horses can also pick it up if bedding and mucking out aren’t keeping the feet clean and dry.
Poor hoof balance, deep central sulci, and tight frog clefts can make it easier for thrush to settle in. Sometimes a strong smell or frog soreness may be made worse by other hoof issues, which is why persistent cases are worth a closer look.
Less commonly, similar signs can be seen with deeper hoof infection or another problem affecting the foot, particularly if there’s lameness, marked pain, or swelling.
What To Do
Pick out the hooves daily and keep the frog area as clean and dry as you can. If turnout is muddy, try to reduce time standing in wet ground where possible and keep stable areas as dry and well mucked out as you can.
Watch for changes over a few days. If the smell, discharge, or soreness is getting worse, or there’s no improvement with sensible hoof hygiene, it’s time to speak to your vet or farrier for advice.
When To Contact A Vet
Contact your vet if the horse is lame, very sore, or unwilling to let you clean the hoof. You should also get advice if there is swelling, heat, a deep crack or hole in the frog, bleeding, or if the thrush isn't improving after a few days of careful daily hoof cleaning and dry management.
It’s especially sensible to call sooner if your horse seems unwell, the problem is in multiple feet, or you’re unsure whether you’re dealing with thrush or something else.
