What specific predators were Welsh Terriers historically built to confront in their dens?

Answer

Foxes, badgers, and otters

The original utility of the Welsh Terrier demanded that it be highly effective underground in confined, dark spaces characteristic of the Welsh hills and valleys. To meet this functional requirement, the breed was developed to have the necessary endurance and courage to confront creatures such as foxes, badgers, and otters in their native dens. This deep-rooted purpose dictated the breed's entire physical and temperamental structure, making effectiveness below ground paramount over aesthetic appearance.
