Overview
If your horse keeps biting at its lower legs, start by checking for mud, rubbing, skin irritation, insects, tiny scabs or signs of feather mites. It could be something simple, but there may be several possible causes, so it’s worth looking closely rather than guessing.
Things To Check
1. Check whether it happens after turnout, in wet ground, after exercise or when the horse is stabled.
2. Look for mud build-up, wet feathers, rubbed areas or hair loss around the lower legs.
3. Feel for heat, swelling, soreness or sensitivity when you touch the area gently.
4. Part the feather and inspect the skin for dandruff, scabs, crusting or small moving specks.
5. Check whether both legs are affected or just one, as that can help you notice whether it’s a general irritation or a more local problem.
6. Look at the rest of the body too, especially the mane, tail and belly, for any signs of itching or rubbing elsewhere.
7. Think about any recent changes in turnout, bedding, grooming routine, wash products or clipping.
Common Causes
One of the most common reasons is simple irritation from mud, dampness or feather being kept wet for long periods. Rubbing from a boot, strap or rough surface can also make a horse nibble at the area.
Feather mites are another possibility, especially if the horse has thick feather, flaky skin or repeated itching around the lower legs. Insect bites or general skin sensitivity can also lead to biting and chewing.
Less commonly, there may be a small wound, a patch of dermatitis or another skin condition that needs a closer look. If the behaviour is repeated or the skin starts looking worse, it’s sensible to keep an open mind about the cause.
What To Do
Clean off any mud gently and dry the legs well, especially around heavy feather. Avoid over-washing, but do keep the area clean enough that you can inspect the skin properly.
Check tack, boots and turnout gear for rubbing points, and make sure bedding, gateways and fence lines are not causing repeated contact.
If you suspect mites or skin irritation, keep a note of when the biting happens, what the skin looks like, and whether it improves with changes in turnout or grooming. That information can be very useful if you need advice later.
If the horse is scratching the same area over and over, it’s worth reviewing the whole leg-care routine, including washing, drying and how often mud is left on the feathers.
When To Contact A Vet
Speak to your vet if the skin is broken, there’s swelling or heat, the horse seems painful, or the biting is getting worse rather than settling. It’s also sensible to get advice if you suspect feather mites but the problem keeps coming back or doesn’t improve with basic management.
