Why is my horse's frog soft and crumbly? | arlo.® Atlas

Read time: 3 minutes

Overview

If your horse's frog is soft and crumbly, thrush is one common reason, especially if there's also a smell, dark discharge or a horse that's been standing in wet, dirty conditions. That said, a crumbly frog can also happen with excess moisture, poor hoof balance, bruising or general hoof wear, so it's best to look at the whole hoof rather than the frog alone.

Things To Check

1. Check whether the frog is soft, smelly, blackened or has a cottage cheese-like discharge, which can fit with thrush-type changes.

2. Look at the footing your horse has been on recently, especially wet turnout, muddy gateways, damp stabling or dirty bedding.

3. Compare both hind and front feet, and both sides, to see if the problem is affecting one hoof more than the others.

4. Feel for heat, tenderness or a stronger reaction when you pick out the hoof or press gently around the frog and heels.

5. Check for cracks, ragged edges, bruising or areas where the frog seems to be losing chunks rather than just looking dry.

6. Notice whether your horse is slightly short-striding, walking carefully on hard ground or seems less willing to land heel first.

7. Look at how often the feet are being picked out and whether the horse has been standing in dirty moisture for long periods.

Common Causes

The most common cause is thrush, which often develops where the hoof stays damp and dirty for too long. The frog can look soft, split or crumbly, and there may be an unpleasant smell.

Constant wetness can also weaken frog tissue even when thrush isn't obvious. Mud, urine-soaked bedding and poor drainage can all make the hoof horn less firm.

In some horses, a crumbly frog is linked to hoof wear, imbalance or a frog that's not being loaded evenly. That can make the tissue look ragged or worn away.

Less commonly, bruising, soreness or another hoof problem may be contributing, especially if the horse is painful or the changes are only in one foot.

What To Do

Pick the feet out daily, or more often if conditions are muddy or wet, and remove any packed dirt or bedding gently.

Try to keep the horse in as clean and dry an environment as you can manage, with dry bedding and decent drainage where possible.

Monitor the frog for smell, discharge, worsening softness or increasing soreness, and make a note if the problem is getting better or worse.

If your horse is shod, or if the hoof shape seems to be changing, speak to your farrier as routine hoof balance can make a difference to how the frog is loading and wearing.

A sensible cleaning routine can also help support day-to-day hoof hygiene, especially during wet weather or after turnout in muddy ground.

Products That May Help

If the issue is linked to wet, muddy or dirty conditions, a hoof-care routine can be useful as part of keeping the area cleaner and easier to manage day to day.
