Until 1977, Dachshunds in the United Kingdom were allowed to be bred between coat varieties (called “crosscoat matings”), so there were wire and smooth coated Dachshies that “carried” genes for different coat types, and in countries where cross coat mating were more common, this was even more pronounced.
In Dachshunds, the wire gene is dominant to all other coat types. Even if a dog has just one W gene, it’ll be a Wire coated Dachshund. The Smooth coat is dominant to the Long coat, and if a Dachshund has one S and one L gene, it will be a Smooth, but it will carry the Long gene which it can pass it on to puppies who can produce “recessive Longs.”
The Long coat is recessive to both the Wire and Smooth coats, so if the dog is Longhaired, he or she has to have two copies of the Long Haired gene. Longhaired puppies are produced by two Longhaired parents.
