Appropriate Breeds for Testing
Several breeds including:
Black Russian Terrier, Chinese Crested, Havanese, Toy Havanese Terrier, Hungarian Vizsla, Irish Terrier, Lagotto Romagnolo, Miniature Poodle, Portuguese Water Dog, Scottish Terrier, Soft Coated Wheaten Terrier, Poodle Standard, Tibetan Terrier, Wirehaired Vizsla

Description:
IC locus (improper coat) for some breeds (such as the Portuguese Water Dog), presents a dog with a lack of density in the coat (furnishing) and has short hair on the head, face and lower legs, rather than a thick, even coat covering the entire body. In some other breeds, the phenotype is desirable.
The dog's genotype also depends on a combination of the L, Cu and IC loci
