Mallenders/Sallenders or Hyperkeratosis


Mallenders and Sallenders can be a heartbreaking and tenacious skin issue. It presents as an accumulation of thickened, crusted scale and scabs on the front and hind legs of horses. Mallenders occurs behind the knees on the front leg while Sallenders 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 Mallenders/ Sallenders. 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 thankfully 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.


If weather permits wash area well with Equiderma Neem Shampoo. Leave shampoo on for 1 hour and rinse. Apply Equiderma Skin Lotion to all buildup and lesions and leave on. Check and reapply lotion every day until all scabbing has lifted off the skin. Observe the area often and reapply as needed. Mallenders/Sallenders is a case of management. To date there is no definitive cure. When you notice additional keratin buildup, reapply 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 wash cloth to aid you in removing the scale.
