Dachshund
they come in three different coat varieties (Smooth, Wirehaired or Longhaired) and can be miniature or standard size.
Dappled dachshunds-The dapple (merle) pattern is expressed as lighter-colored areas contrasting with the darker base color, which may be any acceptable color. Neither the light nor the dark color should predominate. Nose and nails are the same as for one- and two-colored Dachshunds. Partial or wholly blue (wall) eyes are as acceptable as dark eyes. A large area of white on the chest of a dapple is permissible.
Chihuahua
Coat
In the Smooth Coats, the coat should be of soft texture, close and glossy. (Heavier coats with undercoats permissible.) Coat placed well over body with ruff on neck preferred, and more scanty on head and ears. Hair on tail preferred furry. In Long Coats, the coat should be of a soft texture, either flat or slightly wavy, with undercoat preferred. |
I believe that these variations are in the breed standard set by the breed clubs and not by AKC. The YTCA would have to accept the Biewer Terrier as a variant color in its standard before the AKC would allow it in as a Yorkshire Terrier.
I am pretty sure that is not very likely to occur especially with all of the testing that is being done.
