A Sable coat consists of black-tipped hairs; the rest of the hair can be gold to yellow, silver, grey, or tan. The darkness of the coat depends on how much of each hair is black versus the lighter color.
A Phantom is a solid base color with sharply defined markings of a second color appearing above each eye, on the sides of the muzzle, on the throat or chest, on all four legs and feet, and below the tail. Any combination of acceptable colors is allowed.
A Merle coat is a single color (black or brown) with a gene modifier which creates darker patches on a diluted base coat color. This includes Blue or Chocolate Merle accompanied by white markings on the face, chest, feet, and tail with or without tan points that can present themselves on the snout/cheeks, above the eyes, chest, legs, and rear. Merles can also come with little to no white markings and can have Phantom marking on the snout/cheeks, above the eyes, chest, legs, and rear.
With all puppies there is a chance that their color may fade; here are a few examples of puppies that have changed.
