Mallenders / Sallenders or Hyperkeratosis


Mallenders and Sallenders can be a heartbreaking and tenacious skin issue in horses. It presents as an accumulation of thickened, crusted scale and scabs on the front and hind legs of horses.  

Mallanders occurs behind the knees on the front leg while Sallanders occurs in front of the hock on the hind legs.  

The problem occurs most commonly in draft or heavy breeds and horses with feather.  It is a common ailment in Gypsy, Shire, Drum, and Friesian horses and is caused by excessive keratin production.  Keratin is a fibrous protein forming the main structural constituent of hair, feathers, hoofs, claws, horns, etc.   Increased keratin is the reason these breeds have such beautiful feather and is also the reason some develop Mallanders or Sallanders.  

Both disorders cause discomfort for your horse and can lead to lameness.  Excess keratin build up is only the beginning of the issue.  If lesions are allowed to stay on for long periods a secondary bacterial and fungal infection may occur.  There is no cure for the ailment but it can be managed easily.

Equiderma Skin Lotion will gently remove the buildup and address the underlying issues as well.  It is a simple and easy treatment and will have your horses legs soft and smooth and free of scabs, cracks, and pain in no time - We offer a 100% money back guarantee on this promise.


Wash area well with Equiderma Neem Shampoo.  Leave shampoo on for 1 hour and rinse.  Apply Equiderma Skin Lotion to all build up and lesions and leave on.  Check and reapply lotion every day until all scabbing has lifted off the skin.  Observe area often and re-apply as needed.  Mallenders/sallenders is a case of management.  To date, there is no definitive cure.  

When you notice additional keratin build up re-apply Equiderma Skin Lotion.  Equiderma will soften the gunk and allow you to easily remove it.  If it is too cold or for any reason you cannot shampoo your horse.  Follow the instructions with only the skin lotion.  It will do an excellent job on its own although it is important to keep the legs as clean as possible.  Use a warm washcloth to aid you in removing the scale
