Why is my horse lame with a smelly hoof?

Overview
A smelly hoof with lameness is often linked to thrush, especially if the horse has been standing in wet or dirty conditions. It can also be caused by other hoof problems, so it’s worth checking the hoof carefully rather than assuming it’s only the smell.
In many cases, the smell comes from softened frog tissue, trapped debris or infection in the hoof, but soreness, heat or a stronger limp can mean the problem needs more attention.
Things To Check
1. Check whether the smell is coming from one hoof or more than one.
2. Look closely at the frog and clefts for black, smelly material, softness, cracks or loose tissue.
3. Feel for heat in the hoof and look for swelling higher up the limb.
4. Watch how the horse is moving on a straight line and on turns to judge how lame they seem.
5. Check the footing, bedding and turnout area for wet, muddy or dirty conditions.
6. Pick out the hoof and see if stones, packed mud or debris are trapped inside.
7. Note whether the horse is sensitive when the hoof is picked up or when pressure is applied to the frog area.
Common Causes
Thrush is one of the most common reasons for a smelly hoof. It often affects the frog and heel area, especially in wet or unhygienic conditions, and can cause tenderness or lameness if the tissue becomes sore.
Poor hoof hygiene, muddy turnout and damp bedding can all contribute to a strong odour and soft, unhealthy tissue.
Less commonly, a hoof abscess, bruising, a puncture or another deeper hoof issue may be involved. These can also cause lameness, and the smell may be from trapped drainage or damaged tissue rather than thrush alone.
What To Do
Pick out the hoof carefully and remove any mud or debris you can see. Keep the hoof as clean and dry as practical, and review turnout, bedding and stable cleanliness.
Monitor the horse’s movement and the smell over the next day or two. If the hoof is staying wet, try to improve the environment where you can, because repeated dampness often makes hoof problems harder to manage.
If the horse is uncomfortable, avoid heavy work until you understand what’s going on. A mild case may settle with better hygiene and regular monitoring, but persistent lameness needs proper assessment.
When To Contact A Vet
Contact your vet if the lameness is marked, getting worse, or the horse is not happy to put weight on the foot. A foul smell with heat, swelling, discharge or a sudden change in comfort can suggest more than simple thrush.
You should also get advice if the hoof looks deeply damaged, you suspect an abscess or puncture, or there’s no improvement with basic cleaning and management.
