Coat length (common or L1)

Why test for coat length?

Coat length is the defining characteristic of many dog breeds. The Afghan Hound and Shih Tzu are known for their long flowing hairstyles. Others such as the Greyhound have sleek short coats.

In some breeds it is possible for puppies to be born with either long or short hair, for instance Dachshunds and Siberian huskies. Breeders can use this test to find out the likelihood of breeding long or short haired puppies.

The L1 length gene is the most common cause of long-hair in dogs. Dogs with Akita, Samoyed or Siberian husky breeding should also use the L2 test.

The common (L1) and L2 length tests are both included in our shedding panel. Long hair on the couch is much more obvious than short hair!

The L1 variant for coat length is described in Cadieu et al. (2009): doi: 10.1126/science.1177808

Long hair

Breeds such as the Yorkshire Terrier and Lhasa Apso combine the gene for long hair with the gene for furnishings. This combination gives long hair that keeps growing.
