Laugh all you want, but any dog that is tough enough to go into a badger hole and bring out the badger, is a tough little hound.
We had a couple of black & tan slick miniatures when I was a kid (one at a time, not at the same time).
We moved when I was 10, and there was a big brush pile in the back yard. Dachshunds have great noses, so ours immediately knew there was a rabbit nesting in the brush. For several weeks, she worked that brush pile, trying to flush the rabbit. No luck. But then one day when she circled the south side, the rabbit bolted north, towards the house. My sister's big fat lazy tomcat just happened to be sitting there, and his few firing feline synapses told him to reach out and snag the furry blur.
The rabbit was a big one, probably four pounds, way too big for the cat to climb a tree with. And so, he headed under the house, about the same time the dachshund rounded the brush pile to spy
her rabbit in the jaws of another.
Note to cats: going to ground beneath the house is a poor idea when you're trying to abscond with something the badger hound rightly considers to be hers.
As Dad put it, "The cat went under the house with the rabbit, then the dog went in, then the house jumped up and down on the pilings three or four times, and the dog came out the the rabbit. We didn't see the cat for two weeks."
Dachshunds are scary smart, and have a very German personality. They're vindictive, and you don't want to wind up on their bad side.
