My aunt used to have dachshunds. Tough little buggers and excellent hunting dogs, with a built in snap crackle pop kill drive for rats, rabbits and snakes. No, this survival story doesn’t surprise me at all either. I saw the abc article, and she’s a shorthair with good legs and not fat. Show-bred ones are a bit fragile in the back and some have leg and eye issues, but a healthy young one can survive a LOT.
