Quotewith a dachshund's bowlegged stature. It was the size of a chihuahua, differentiating its probable role in Roman Britain from other dogs of the era.
"The fact that this dog was so small and had bowed legs suggests that she probably wasn't bred for hunting,"
Yet the "bow-legged" dachshund was indeed bred for hunting, chasing badgers down burrows; so I don't at all see why this one shouldn't have been (albeit maybe for smaller prey).
