Coat
The Finnish Spitz has a typical double coat, which consists of a soft, dense undercoat and long, harsh guard hairs that can measure one to two inches long. The coat should be stiffer, denser, and longer on the neck, back, back of thighs, and plume of the tail, while remaining shorter on the head and legs.
Males should sport a slightly longer and coarser coat than females who are slightly more refined. The plume of the tail is important to the overall look of the dog and should not be too long as longer tail hairs can give the dog an unkempt look.
The Finnish Spitz "blows coat" or loses its undercoat twice a year. It is imperative that owners brush out the old undercoat so the new coat can grow properly. Excessive undercoat can cause skin problems, and although your dog may look fluffy and full, the undercoat may be causing serious skin problems.
Color
Puppies look similar to a red fox cub. They are born dark gray/black/brown or fawn, with a large amount of black. The color of the adult dog cannot really be assessed until about four months, but even then the color may change.
The adult color must be red but can be of almost any shade, varying from pale honey to dark chestnut. There are no preferences over shades as long as the color is bright and clear with no hints of dullness, which is of most importance. The coat should never be of a solid color. It should be shaded and without any defined color changes.
