i don’t think anyone said they were dachshunds. The story said most of the dogs were dachshund-terrier mix. Based on their appearance I’d say that’s a pretty accurate description.
Of course, the dachshund was originally bred to hunt badgers, so they are short-legged little bad-asses, and would be perfectly capable of perpetrating a fatal attack on a person - especially a pack of them.
I hear badgers are pretty bad ...
