The Manchester Terrier, from which the Toy Manchester Terrier was bred, was developed in the 19th century from crosses between an old Black and Tan Terrier with the Whippet, along with other breeds, primarily for rat-catching. In England, another breed was also developed in the 19th century in Manchester, the English Toy Terrier, as a separate breed from the Manchester Terrier. The English Toy Terrier was a popular pet in Victorian England, and bred to be very small, some weighing as little as 1 kg (2.2 lbs.)
