Thanks for the welcome!
Dachshunds and all the "to ground" terrier breeds, are all fierce, being bred to go into the varmint's tunnels and either kill it underground, or flush it out.
Can you imagine a small dog, trying to kill a fox, badger, or skunk, in a small, dark den tunnel, underground?
Weird how the people back then developed several breeds of small terriers, specifically for these jobs. I sure can't see it, but times were different, back then. Varmint or game killing was expected work for most dogs.
Dogs were viewed and used as helpers, not pets.
