The Fiber You may have a wonderful source of material to produce soft and lovely yarns sleeping on your sofa and digging up your flower beds. Dog hair was the one fiber spun on this continent before the Spaniards introduced sheep. The quality of the yarn produced from dog hair will vary widely depending on what type of hair is used. Generally dogs are two coat animals, with a hairier outer coat, and a soft downy inner coat. Dog hair is heavier and warmer than wool, and since the fibers have little or no crimp has no elasticity.
All dog hair is useable - for something.
With some breeds the difference between the outer and inner coats is great and you will want to separate them before spinning. You will also want to sort by color before spinning. Even coats that look to be one color when worn by the dog are actually made of many colors. If you are blending dog hair with other fibers, lightly card on hand or drum carders. It will be easier to handle the doghair if it can be sandwiched in between layers of a less staticy fiber.
