Improper Coat / Furnishings (RSPO2-related) - Dog

What does this test analyse?

This genetic test analyses the RSPO2 167 bp 3′UTR insertion in dogs. The trait is known as Improper Coat, Furnishings, IC or the furnishings pattern with moustache, beard and eyebrows. RSPO2 influences coat texture and the pattern of longer hair around the muzzle, eyebrows and legs.

What does this coat trait mean?

Dogs carrying the Furnishings allele usually develop visible facial furnishings, such as a moustache, beard and eyebrows, often with a rougher or wire-like coat appearance. Dogs without this allele do not carry the RSPO2-driven furnishings effect. In breeds or crosses where furnishings are expected, this may appear as a shorter, smoother or non-standard coat often called Improper Coat.

Inheritance and result

The Furnishings allele acts as an autosomal dominant trait: one copy is usually enough to produce furnishings. Absence of the Furnishings allele on both chromosomes gives an N/N result and means the dog does not carry this specific furnishings effect.

Result at a glance

• N/N - no RSPO2 Furnishings allele detected; the dog will not pass on F.
• N/F - one copy of the Furnishings allele; the dog can pass on either F or N.
• F/F - two copies of the Furnishings allele; the dog passes F to all offspring.

Practical value of this test

This test is particularly useful for breeders who want clearer expectations for coat appearance, crossings and litter planning. The result helps predict whether puppies can develop furnishings or may have an unfurnished or Improper Coat appearance in lines where that is undesirable. It supports targeted breeding selection, clearer communication with puppy buyers and better interpretation of coat variation in doodles, water dogs, terriers and other breeds or crosses where this trait matters.
