Their origins can be traced back to the 19th century, where they were developed as working dogs for controlling rodent populations on farms and in cities. They were known for their agility, intelligence, and tenacity in hunting rats.
Their ancestry likely includes various terrier breeds, including the American Pit Bull Terrier, the Manchester Terrier, and the Whippet, resulting in their unique appearance and temperament.
While the Rat Terrier is a relatively recent breed, its history is deeply intertwined with the agricultural and urban development of America, where it played a crucial role in pest control.
