Overview
Dry, flaky skin under the feathers is often linked to mallenders or sallenders, which are common skin changes seen on the back of the knees or hocks. It can also be caused by mud, sweat, irritation, grooming friction, or an underlying skin issue, so it’s worth checking the area carefully rather than assuming it’s one thing.
Things To Check
1. Check exactly where the flakes are appearing. Mallenders usually affects the back of the knees, while sallenders is more often seen at the back of the hocks.
2. Look for redness, heat, swelling, scabs, cracking, or any oozing, as these can suggest the skin is more irritated than it first appears.
3. Feel whether the area seems sore when you touch it or when you pick up the leg, as discomfort can point to a more active problem.
4. Think about whether it’s worse after turnout, muddy conditions, exercise, or clipping, since moisture and friction can make things look or feel worse.
5. Check the feathers for trapped mud, sweat, bedding, or grime, because build-up can contribute to irritation and flaky skin.
6. Note whether the skin is dry and flaky only, or whether there are thicker crusts, hair loss, or repeated rubbing, as that may suggest a different cause.
7. Compare both legs. If only one side is affected, it can sometimes help narrow down whether irritation, pressure, or local trauma is involved.
Common Causes
Mallenders and sallenders are common causes of dry, flaky skin under the feathers, especially in hairy breeds. They usually show up as dry, scaly skin and may come and go.
Skin irritation from mud, sweat, damp bedding, or friction from feathers can also cause flaking. Overgrooming or harsh washing may make sensitive skin look worse too.
Less commonly, underlying skin disease, parasites, or infection may be involved, especially if the area is sore, swollen, crusted, or keeps coming back.
What To Do
Keep the area as clean and dry as you reasonably can, especially after muddy turnout or exercise. Gentle grooming and careful washing may help remove surface build-up without irritating the skin further.
Avoid picking at scabs or scrubbing the area hard, as that can make the skin more inflamed. If feathers are trapping dirt and moisture, regular monitoring and sensible coat care can help you spot changes early.
Take a photo every few days if the skin is changing, so you can tell whether it is settling or getting worse. If it seems linked to a particular routine, such as turnout, tack, or washing, that can be useful to note.
When To Contact A Vet
Speak to your vet if the skin becomes painful, swollen, hot, cracked, or starts to ooze, or if your horse is repeatedly getting the same problem despite careful management. Ongoing or worsening signs may need a closer look to rule out infection or another skin condition.
Products That May Help
If your horse has dry, flaky skin under the feathers, a gentle washing and coat-care routine may be useful as part of day-to-day management, especially if the area gets muddy or build-up is happening.
