I'm not sure if we have many breeders that visit this adopt/rescue/lost board. There are breeders at the top of the page. Perhaps you can contact one of them and ask your question. Also in the left hand column it has Dachshund Colors & Patterns maybe you can find your answer there.
The Hot Dog Blog might be another place to present your question. There are some breeders on that board. Do not advertise to sell your puppies, that is definitely not allowed but I'm sure they will take your questions. http://hotdogblog.com/
Good luck, if you can't find anyone to help you let me know and I'll check further.
