Mallenders and Sallenders can be a demoralising and stubborn skin condition found in Cobs and heavy horses. It first appears as an build up of thickened, crusted scale and scabs on the front and hind legs of horses. It is sometimes known as "Cob Knee". Sallenders occurs in the crease of the knee on the front leg and Mallenders is present in front of the hock on the hind legs. This condition effects mostly Draft or heavy breeds, although it can be found in many horses that are heavily feathered. As a Farrier I often come across Sallenders and Mallenders Gypsy, Shire, Drum and Friesian horses. The cause of Sallenders and Mallenders is the over production of keratin. Keratin is the building block of hair and horn. It is the fibrous protein.
