Why do Dachshunds have such long bodies and short legs?

Look at a Dachshund. That long body. Those stubby little legs. They look like someone stretched a regular dog on a taffy machine and forgot to stretch the legs too. But here's the thing — Dachshunds weren't born weird. People made them this way on purpose, over hundreds of years, by carefully choosing which dogs got to have puppies.
It starts in Germany, about 600 years ago. Farmers had a problem: badgers. Badgers dug deep tunnels under fields and ate crops and chickens. They were tough, mean little tanks with claws and teeth. Someone had to go down into those dark burrows and chase them out. A regular dog? Too big. Wouldn't fit.
