The Manchester Terrier has been known by several names throughout its long history, each reflecting different aspects of the breed's origins, characteristics, or development. The breed's original designation was the Black and Tan Terrier, a descriptive name that referenced its distinctive coloring and terrier type. This name persisted for centuries in England, where these sleek, athletic dogs earned fame for their ratting prowess and hunting abilities.
The transformation to Manchester Terrier occurred in the 19th century when the breed's development centered in Manchester, England, a thriving industrial city where rat control was essential. Samuel Handley of Manchester is credited with stabilizing the breed type, and the concentration of breeding and showing activities in Manchester led to the breed adopting the city's name. By 1860, these dogs had become so closely associated with Manchester that the name Manchester Terrier had largely replaced the earlier Black and Tan Terrier designation.
The breed earned the charming nickname "Gentleman's Terrier" during the Victorian era, reflecting its refined appearance, dignified demeanor, and popularity among fashionable society. Unlike many terrier breeds bred exclusively for rough farm work, the Manchester Terrier's sleek coat, clean habits, and elegant build made it suitable for both working-class ratting duties and as a companion in more refined households. This dual-purpose capability and sophisticated appearance distinguished it from scruffier terrier types.
In the United States and Canada, the breed exists in two size varieties that share the same breed standard with differences only in weight and ear options. The Standard Manchester Terrier is the larger variety, weighing between 12 and 22 pounds, while the Toy Manchester Terrier weighs 12 pounds or less. This division reflects historical preferences for smaller companion dogs, particularly during the Victorian era when miniaturized versions of popular breeds became fashionable. The Toy variety was developed by breeding the smallest Standard Manchester Terriers together, eventually creating a diminutive version that maintained all the breed's essential characteristics.
The relationship between the Manchester Terrier and the English Toy Terrier (Black and Tan) deserves clarification, as these breeds share common ancestry but developed differently in various countries. In the United Kingdom, the smaller Manchester-type terriers became known as the English Toy Terrier (Black and Tan) and developed as a separate breed with its own standard and registry. In the United States and Canada, however, the small Manchester-type terriers maintained their connection to the Standard variety, and both sizes are considered varieties of the same breed rather than separate breeds.
This structural difference has created some confusion among fanciers and the general public, particularly when discussing international breeding programs or comparing pedigrees across kennel club jurisdictions. The American Kennel Club and Canadian Kennel Club recognize two varieties of one breed, while The Kennel Club (UK) and most international kennel clubs recognize the English Toy Terrier as distinct from the Manchester Terrier, though historically they share the same foundation stock.
The Manchester Terrier has been formally recognized by all major kennel organizations worldwide, reflecting its status as an established, historic breed. The American Kennel Club first recognized the breed in the late 19th century, initially showing Standard and Toy varieties in separate groups. The Standard Manchester Terrier competes in the Terrier Group, while the Toy Manchester Terrier shows in the Toy Group, though they share the same breed standard with only size and ear-type differences.
The United Kennel Club granted formal recognition to both varieties in 1992, placing them together as one breed with two varieties. The UKC allows both varieties to compete and be registered under the same breed designation, emphasizing their essential unity despite size differences.
The Fédération Cynologique Internationale recognizes the Manchester Terrier in Group 3 (Terriers), Section 1 (Large and Medium-sized Terriers), standard number 71. The FCI does not recognize the Toy variety as part of the Manchester Terrier breed, instead recognizing only the Standard size. The smaller dogs of Manchester Terrier type are recognized internationally through the English Toy Terrier (Black and Tan) breed, which has a separate FCI standard.
The Canadian Kennel Club follows the American model, recognizing both Standard and Toy varieties as part of the same breed with the same breed standard. Dogs can be shown in either variety based on weight, and breeding between varieties is permitted, with offspring registered in the appropriate variety based on their adult weight.
The Kennel Club of the United Kingdom maintains separate breed standards for the Manchester Terrier and the English Toy Terrier (Black and Tan), treating them as distinct breeds despite their shared ancestry. This reflects the historical development of the breed in Britain, where size varieties diverged into separate breed populations with independent breeding programs, clubs, and showing schedules.
The American Manchester Terrier Club serves as the AKC parent club, representing both Standard and Toy varieties and promoting responsible breeding, education about the breed, and support for fanciers. The club maintains the breed standard, organizes specialty shows, and works to preserve the breed's health, temperament, and working heritage. Similar national breed clubs exist in many countries, all working toward similar goals of breed preservation and promotion while respecting the organizational structures and recognition patterns of their respective national kennel clubs.
