The R-spondin 2 (RSPO2) gene influences both the wiry texture and a growth pattern of the coat. The growth pattern of the coat, also known as “furnishings”, increases hair growth on the face and legs and is typified by the canine moustache and eyebrows. The term “furnishings” refers to the longer mustache and eyebrows seen in wire-haired dogs and other breeds. In breeds such as the Portuguese Water Dog, Labradoodle and Goldendoodles furnishings can be variable, but are the breed standard. Portuguese Water Dogs without furnishings are referred to as having an “Improper Coat” which is characterized by short hair on the head, face and legs. The Improper Coat/Furnishings test (H848) tests for the genetic status of the RSPO2 gene. The RSPO2 gene has two variants (alleles). The allele N is dominant and results in “furnishings”. Only when the dog has two copies of the recessive allele IC the dog does not have “furnishings”. Some breeds, such as the Airedale Terrier, are fixed for the dominant allele N.

The Improper Coat/Furnishings test encloses the following results:

Result Improper Coat/Furnishings test Coat
N/N Dog has furnishings in some breeds this means dog has a normal coat with longer hair on the muzzle and eyebrows
N/IC Dog has furnishings in some breeds this means dog has a normal coat with longer hair on the muzzle and eyebrows
IC/IC Dog does not have furnishings, in some breeds this means an Improper coat without longer hair on the muzzle and eyebrows
