While the breed may produce fewer allergens, care should be taken for severe allergies.Shed Samoyed fur is sometimes used as an alternative to wool in knitting, with a texture similar to angora. The fur is sometimes also used for the creation of artificial flies for fly fishing. The AKC Standard requires 21–23.5 inches (53–60 cm) at the shoulder for males, and 19–21 inches (48–53 cm) for females. The topcoat contains long, coarse, and straight guard hairs, which appear white but have a hint of silver coloring. This top layer keeps the undercoat relatively clean and free of debris. The under layer, or undercoat, consists of a dense, soft, and short fur that keeps the dog warm. The undercoat typically sheds heavily once or twice a year, and this seasonal process is sometimes referred to as 'blowing coat'.
