Overview
Hair loss around the feathers is often caused by irritation rather than something dramatic. Feather mites are one possible reason, but rubbing, mud, damp skin, lice, allergies or minor skin damage can also play a part. The useful first step is to look closely at the skin and notice whether the loss is patchy, scurfy, itchy or linked to turnout, grooming or wet weather.
Things To Check
1. Check whether the feather loss is patchy or more even, and whether the skin underneath looks normal or irritated.
2. Look for scabs, dandruff-like flakes, redness, swelling, heat, broken skin or any discharge.
3. Notice whether your horse is stamping, rubbing, biting at the legs or fussing more than usual.
4. Think about recent mud, rain, standing in wet bedding or damp turnout, as moisture can make skin problems worse.
5. Check whether the feathers are being clipped, washed, brushed hard or tangled in a way that could cause breakage.
6. Look at the other legs and the mane or tail to see if the hair loss is appearing elsewhere too.
7. Watch for any changes after turnout, rug changes, grooming or a new field, as that can give a useful clue.
Common Causes
Feather mites are a common concern because they can cause itchiness, scurf and hair breakage around the lower legs. The skin may look dry, flaky or irritated, but that alone doesn’t confirm mites.
Mud and damp conditions can soften the skin and make feathers tangle, rub or break more easily. This can happen alongside mild soreness or chafing, especially in horses with thick feathers.
Rubbing or stamping from irritation, including insect bites or general itchiness, can also lead to hair loss. Sometimes the feathering is damaged simply because the horse keeps worrying at the area.
Lice, fungal skin issues, allergic skin reactions or friction from tack, bandages or stable surfaces are other possibilities. Less commonly, skin infection or a more widespread health issue may be involved if the area looks sore, swollen or is getting worse.
What To Do
Start by keeping the area as clean and dry as you reasonably can without over-washing. If the feathers are caked in mud, gentle washing and careful drying may help you see what the skin actually looks like.
Keep a note of when the hair loss is worse, what the skin looks like and whether your horse is itchy. A few photos over several days can be useful if you later need advice.
Check the stable and turnout conditions too. Wet bedding, muddy gateways and persistent damp can all make feather problems harder to settle.
Avoid harsh scrubbing or repeatedly picking at scabs, as that can make irritation worse. If the skin is sore, swollen or clearly uncomfortable, it’s best to speak to your vet rather than keep experimenting at home.
Products That May Help
If your horse’s feathers are looking dry, dirty or scurfy, a gentle wash routine can help support day-to-day coat and skin care without overdoing it.
