The person who posted the video stated that theirs was a double dapple - a common mistake. What they have is a piebald dapple. Someone probably charged them for an AKC recognized mix, but that is not what they have techinically (I do not care one bit about those classifications because I do not show or breed).
Dachshunds have more colors, patterns and coat types than an other breed.
The AKC will recognize one color and one pattern. Pippin, and this running pup are one color with two patterns - black and tan is the color, the patterns are piebald (the white with colored circle patterns) and dapple (called merle in all other breeds - the grayish tones with freckles of color on the skin and coat)
You pay twice as much for an AKC acceptable name (but if you try to show these dogs, they will be eliminated), so many iffy breeders just lie about this because those who do not much about dachsies do not know any better.
I appreciate people who are civil, whether they mean it or not. Be civil. Do not cherish your opinion over my feelings. There's a vanity to candor that isn't really worth it ~ Richard Greenberg
