Overview
If your horse’s hoof heat and lameness are getting worse, it’s a sign that something is still actively bothering the foot. That can happen for a number of reasons, from an abscess or bruise to thrush, nail-related pain, or a more serious hoof problem. It’s worth checking the foot promptly, because worsening lameness usually means the issue isn’t settling on its own.
Things To Check
1. Compare both front feet and both hind feet for differences in heat, shape and how the horse is standing.
2. Look for a stronger digital pulse in the affected leg, if you know how to check it.
3. Pick out the hoof carefully and check for a nail, stone, crack, packed mud, foul smell or black, crumbly areas.
4. Check whether the horse is worse on hard ground, turning, backing up or after turnout and exercise.
5. Look for swelling higher up the leg, sensitivity when the hoof is tapped, or a change in how the horse bears weight.
6. Think about any recent shoeing, trimming, lost shoe, knock or wet, muddy conditions.
7. Note whether the horse is eating normally and whether the lameness appeared suddenly or has been building up.
Common Causes
An abscess is one of the most common reasons for a hot, painful hoof that seems to get worse before it gets better. Bruising, a stone bruise or a sole injury can also cause increasing pain, especially if the horse keeps moving on it.
Thrush or other hoof hygiene problems may make the foot sore, particularly if there’s a smell, dark discharge or a soft, damaged frog. A shoe issue, such as a shifted shoe, nail pressure or an imbalance after trimming, can also cause heat and worsening lameness.
Less commonly, a penetrating injury, deeper infection or a more complex hoof condition may be involved. If the horse has marked pain, won’t bear weight properly, or the lameness is progressing, it needs veterinary assessment.
What To Do
Keep the horse as comfortable and quiet as you can while you inspect the foot. Remove obvious mud and dirt, then pick out the hoof gently so you can look for anything trapped in the sole or frog.
Limit exercise and avoid asking the horse to work through the lameness. If turnout makes the foot worse, reduce movement and keep the horse on the most suitable surface available.
Make a note of what you find, including which foot is affected, how much heat is present and whether the horse is more or less lame than earlier. If there’s a shoeing or trimming issue, contact your farrier as well as your vet if the lameness is worsening.
When To Contact A Vet
Contact your vet promptly if the lameness is getting worse, the horse is very sore, won’t put weight on the foot, or you suspect a puncture wound, infection or deeper hoof problem. A worsening hot hoof can be a sign that needs prompt assessment rather than waiting to see if it settles.
If the horse also has fever, swelling up the leg, or seems unwell, don’t delay getting advice.
