A dominant variant of the R-spondin-2 gene produces the longer mustache and eyebrows seen in wire-haired dogs and other breeds.
Phenotype: Dogs with furnishings have long mustache and eyebrow hair.
Mode of Inheritance: Autosomal dominant
Alleles: N = No furnishings, F = Furnishings
(For Improper Coat: N = No improper coat, IC = Improper Coat)
Breeds appropriate for testing: Many breeds including Airedale Terrier, Australian Terrier, Bearded Collie, Bichon Frise, Black Russian Terrier, Border Terrier, Bouvier Des Flandres, Briard, Brussels Griffon, Cairn Terrier, Chinese Crested, Dachshund, Dandie Dinmont Terrier, Fox Terrier (Wire-haired), German Wirehaired Pointer, Glen of Imaal Terrier, Goldendoodle, Havanese, Irish Terrier, Irish Wolfhound, Jack Russell Terrier (and related breeds), Kerry Blue Terrier, Labradoodle, Lhasa Apso, Maltese, Norfolk Terrier, Old English Sheepdog, Petit Basset Griffon Vendeen, Poodle (all varieties and related crosses), Portuguese Water Dog, Schnauzer (all varieties), Scottish Deerhound, Shih Tzu, Silky Terrier, Skye Terrier, Soft Coated Wheaten Terrier, Spinone Italiano, Welsh Terrier, West Highland White Terrier, Wirehaired Pointing Griffon, Yorkshire Terrier, and Crossbreeds
Explanation of Results:
Dogs with N/N genotype (IC/IC in the Improper Coat test) are expected to lack furnishings. They cannot transmit this furnishing variant to their offspring, and they will transmit the non-furnishing variant (Improper Coat) to all of their offspring.
Dogs with N/F genotype (N/IC in the Improper Coat test) are expected to display furnishings but have a copy of the non-furnishing variant. They may transmit this furnishing variant to 50% of their offspring and the non-furnishing variant (Improper Coat) to 50% of their offspring.
Dogs with F/F genotype (N/N in the Improper Coat test) are expected to display furnishings. They will transmit this furnishing variant to all of their offspring, and they cannot transmit the non-furnishing variant (Improper Coat) to their offspring.

Furnishings refers to the longer mustache and eyebrows seen in wire-haired dogs and other breeds. A dominant variant (167bp in the 3'-UTR sequence) of the R-spondin-2 (RSPO2) gene produces this desired texture and growth pattern of fur.
Improper Coat: The breed standard for Labradoodle, Goldendoodles, and Portuguese Water Dog requires “furnishings”. In these dog breeds, lack of the dominant RSPO2 variant (IC) causes Improper Coat which is characterized by short hair on the head, face, and legs.
Note: Furnishings and Improper Coat are the same test with different interpretations.
Dog has furnishings and carries 1 copy of the non-furnishing gene.
Dog has furnishings. All offspring will have furnishings.
Improper Coat results reported as:
Improper Coat (RSPO2)
No copies of Improper Coat, normal,dog will have longer hair on the muzzle and eyebrows.
1 copy of Improper Coat, carrier, dog will have longer hair on the muzzle and eyebrows.
2 copies of Improper Coat, dog has Improper Coat, dog will NOT have longer hair on the muzzle and eyebrows.
