Affenpinschers often appear on lists of dogs that allegedly do not shed (moult). Every hair in the dog coat grows from a hair follicle, which has a three phase cycle, as do most mammals. These cycles are: anagen, growth of normal hair; catagen, growth slows, and hair shaft thins; telegen, hair growth stops, follicle rests, and old hair falls off—is shed. At the end of the telegen phase, the follicle begins the cycle again. The length of time of the growing and shedding cycle varies by breed, age, and by whether the dog is an inside or outside dog. 4 Shedding. Shedding.
