Dappling is a coat pattern found in Dachshund dogs, and a dog is considered a double dapple if both parents of the Dachshund have dapple coats. However, there are very large risks associated with breeding two dapples together, such as birth defects leaving the double dapple blind, deaf or both.
The double dapple coat is officially recognized by the American Kennel Club as a Dachshund coat pattern, and many breeders breed double dapples in hopes of breeding a show dog. The combination of a white coat combined with the dappling coat pattern is unusual and striking.
Double dapple Dachshunds are confused with piebald Dachshund because both dogs have patches of white fur. However, a double dapple typically has a jagged white pattern, whereas a piebald has a symmetrical pattern.
