Description |
One of the most obvious gross morphological differences among dogs of different breeds is the length of their hair. For the majority of registered dog breeds, the breed standard allows only one hair length. However, variable hair lengths are allowed by the standard for some breeds, such as collies, Border collies, dachshunds and St. Bernards. In other breeds, such as Pembroke Welsh Corgis, the occasional appearance of long-haired dogs (also called “fluffies” in this breed) has been a problem for breeders. It has recently been demonstrated in some dog breeds (e.g. Welsh Corgi, Collie, Border Collie, German Shepherd Dog, Miniature long-haired and Smooth Dachshund) that a missense mutation is associated with the hair-length differences among these breeds. Long-haired coat length is inherited a an autosomal recessiv trait, therefore dogs that are carriers of the long hair mutation will appear to be normal (short hair) themselves but will likely pass on the long-hair mutation 50% of the time. Long hair is also know as Fluffy is some breeds.
The DNA test allows to distinguish between 3 possible genotypes:
1. L/L Short Hair having 2 copies of the normal short-hair allele 'L'.
2. L/l Short Hair carrying the long hair mutation - carrier having 1 copy of the normal short-hair allele 'L' and 1 copy of the long-hair mutation 'l'.
3. l/l Long Hair having 2 copies of the long-hair mutation 'l'.
Short Hair (L) is dominant over Long Hair (l)
Please note that this test Coat Length I is valid for all dog breeds, however, in the breeds listed below you should test for this mutation (Coat Length I) and for another mutation (Coat Length II) which is also responsible for Coat Length: Afghan Hound, Akita Inu, Alaskan Malamute, ChowChow, Eurasian, Husky, Prager Rattler and Samoyed

2 ) Coat (hair) Length II ( Long or Short Hair)
|
Note |
This mutation Coat Length II is only valid for Afghan Hound, Akita Inu, Alaskan Malamute, ChowChow, Eurasian, French Bulldog, Husky, Prager Rattler, Saluki and Samoyed, however it is important to point out that these breeds should also be tested for Coat Length I which is valid for all dog breeds. One test will not give you the full status.

Description |
The gene responsible for curly coat has also been identified. Most breeds are fixed for either curly or not-curly, but in breeds where there is variation, dogs may now be tested to see if they carry zero, one or two copies of the curly or non-curly versions of the KRT71 gene. It is possible for a curly dog to carry the non-curly trait.
Please note that the c2 variant has been added to this panelat not additonal cost. The test now detects both C1 and C2. The C2 variant found in a number of breeds including: Curly Coated Retriever, Chesapeake Bay Retriever, Lagotto Romagnolo, Spanish Water Dog, Bichon Frise and Irish Terrier

Trait of Inheritance |
The curly hair trait in dogs is inherited as an incomplete dominant trait . This means that:
- Dogs with two copies of the curly variant (C/C) will have curly coats.
- Dogs with one copy of the curly variant (N/C) will have wavy coats.
- Dogs with no copies of the curly variant (N/N) will have straight coats.
So, it’s not purely dominant or recessive but rather shows incomplete dominance.
- C1 Variant: This mutation is commonly found in breeds like Poodles and Bichon Frises. Dogs with one copy of this variant (N/C1) have wavy coats, while those with two copies (C1/C1) have curly coats.
- C2 Variant: This mutation is found in breeds such as Curly-Coated Retrievers and Lagotto Romagnolos. Similar to the C1 variant, dogs with one copy (N/C2) have wavy coats, and those with two copies (C2/C2) have curly coats2.
A dog with one copy of the C1 variant and one copy of the C2 variant in the gene is likely to have a curly coat. Both variants influence the curly hair trait, so having one copy of each (N/C1) and (N/C2) generally leads to a curly coat, much like having two copies of either variant (C1/C1 or C2/C2).

Description |
Furnishings refer to the longer facial hair around the eyebrows, moustache, and beard commonly seen in many breeds, including the wirehaired breeds. Presence of furnishings is dominant to the unfurnished version of the gene, which depending on breed may also be referred to as satin, or sleek. LABOKLIN offers a test to see if a furnished dog carries the recessive unfurnished trait. This coat variant is called 'improper coat' in portuguese waterdogs. In Hungarian Wirehaired Vizsla (Vizslak) this it is called Wirehair.
