Furnishings (DNA marker tested RSPO2) The presence of "Furnishings" is usually observed in "wire-haired" dogs but is best characterized by a longer mustache and eyebrow facial hair pattern. Like Curl this is also inherited as an autosomal Dominant trait. Therefore, dogs having only 1 copy of the furnishings allele will appear to have "furnishings", but will likely pass on the non-furnishings allele 50% of the time.
