My 3 thirty day period old Chihuahua is white with a black location near tail. She also features a black ears, & black & white muzzle. At about two months she started out creating black places or “freckles” all during her white and on her white muzzle and stomach. https://teacup-chihuahuas-for-sal03333.imblogs.net/80088131/chihuahua-puppies-for-sale-by-owner-options
