Dachshunds come in three coats: Smooth, Long and Wire. Inter-varietal mating was officially stopped by the UK Kennel Club in 1977, but “recessives” still appear from time to time.
Wire-hair is dominant over Smooth and Long.
Due to the presence of recessive coat genes, it is possible to get Long or Smooth coated puppies in Wire litters. “Recessive Smooths” are not uncommon. A Recessive Smooth is not the same as a “Pin Wire“, the former having no furnishings at all, while the latter will have some degree of facial and leg furnishings. Pin Wires will very often be much darker in colour (more like Black/Tan) than “normal” wire coats and rarely need to have their coats stripped.
Smooth-hair is dominant to Long, but recessive to Wire.
Due to the presence of recessive coat genes, it is possible to get Long coated puppies in Smooth litters.
Long-hair is recessive to both Smooth and Wire.
The long-haired coat should be soft and straight, or only slightly waved. There should be feathering on the ears, underparts and on the tail. In general, the coat should be flat, not fluffy.
It is not possible to get Smooth or Wire coated puppies in a “Long mated to Long” litter.
