My mini-Dachshund has some sort of Napoleon complex and goes nuts around tall people. In my neighborhood there are a lot of tall black guys, so he could also be construed as racist.... but how idiotic does that sound?

I think perhaps a new, unbiased dog would be a better solution, say a black labrador, which could be given the job despite the absence of any training, and in the face of competition from several far more qualified, though obviously evil and racist, white dogs. It could be a kind of canine affirmative action.
