Furnishing - Improper Coat (Coat type Dog)

• Furnishing (wire-haired) refers to the length and texture of the hair.
• The dog tends to have wavy to curly coat and very pronounced hair on eyebrows and beard.
• This coat structure occurs in many different breeds: Portuguese Water Dog, Lagotta Romagnolo, Poodle, Soft Coated Wheaten Terrier, Dachshund, Brussels Griffon, Chinese Crested Dog, German Wirehaired, Havanese, Irish Terrier, Schnauzer, Scottish Terrier, Tibetan Terrier, etc.
• In some breeds this trait is preferred, in others it is required.
• However, if this feature is not present in breeds where it is required, the normal coat texture is called "improper coat".

Inheritance: autosomal-dominant

→ Animals with one or two copies of the gene (F/n, F/F) show the phenotype Furnishing. Animals with no copy of the gene have a "normal" coat.

Genotypes:

n/n = Two copies non-functional

No variant for furnishing, the dog has a "normal" coat, sometimes called "Improper Coat".

F/n = One copy intact and one copy non-functional

The dog shows the coat structure Furnishing and passes it on to 50% of its offspring.

F/F = Two copies functional

The dog shows the coat structure Furnishing and passes it on 100% to its offspring.
