My cousins had, I kid you not, a dachshund/doberman cross-breed.

I still shudder to think about the act of miscegenation and the mechanics themselves.

This dog was, well, remember the movie The Mask, in the scene where the dog put the mask on, and was all teeth? It was a dachshund on long legs, and with a doberman's giant bite. A very slight and slender dog, a real weiner dog, but at waist height and with more teeth than a shark.
