Terrier breeds were primarily developed in England to serve as versatile working dogs, particularly for tasks involving vermin control and hunting. Their development was driven by several specific functional needs:12

Vermin Control: Many terriers were bred to rid barns and stables of rodents, often by digging them out of burrows.12
Hunting: They were essential in foxhunting, where they were used to drive foxes from their dens. Some breeds, such as the border terrier, were specifically developed to protect livestock from foxes.134
General Utility and Sport: Beyond pest control, they were used for guarding homes and barns, as well as for various forms of entertainment, including rat killing, bull- and bearbaiting, and dogfighting.12

Because these dogs were required to confront prey that often fought back, they were selectively bred for a tenacious, fearless, and pugnacious temperament. Their physical traits—such as their size, wiry coats, and jaw structure—were shaped by the need to work underground or in rugged conditions, with form following function to ensure their effectiveness as hunters.12
