The English Toy Terrier is recognized by several names that reflect both its British origins and its classification as a toy breed descended from larger terrier stock. While the official registered name with American kennel clubs is "Toy Manchester Terrier," the breed is commonly known as the "English Toy Terrier" in the United Kingdom and many other countries, a name that emphasizes both its English heritage and its toy classification. This geographic distinction helps differentiate the breed from other toy terriers and acknowledges its development in Victorian England where miniature dogs became fashionable among city dwellers who wanted the spirited personality of terriers in a more compact, apartment-friendly package. The name variations reflect different kennel club naming conventions rather than actual breed differences, as the English Toy Terrier and Toy Manchester Terrier are essentially the same breed recognized under different names in different countries.
Historically, these dogs were also known as "Black and Tan Toy Terriers," a descriptive name that highlighted their distinctive coloring which remains the only acceptable color pattern for the breed. This name emphasized the breed's striking appearance with its jet black coat and rich tan markings on specific body parts including the muzzle, above the eyes, on the chest, legs, and under the tail. The precise placement and richness of these tan markings are considered important breed characteristics, with clearly defined boundaries between the black and tan areas being highly prized by breeders and judges. Some older texts and historical references occasionally mention "Miniature Black and Tan Terrier" or simply "Toy Terrier," though these names have largely been replaced by the more specific breed designations used today.
The breed's relationship to the Manchester Terrier is significant and explains the naming conventions in different countries. English Toy Terriers were developed by selectively breeding the smallest Manchester Terriers together to create a toy-sized version that maintained all the larger breed's characteristics including their rat-catching ability, terrier temperament, and distinctive black-and-tan coloring. In the United Kingdom, the Kennel Club maintains separate breed registries and standards for Manchester Terriers and English Toy Terriers, treating them as distinct breeds despite their common ancestry. In the United States and some other countries, the American Kennel Club treats them as size varieties of the same breed, with the larger dogs registered as Manchester Terriers and the smaller ones registered as Toy Manchester Terriers, both competing in their respective size groups but sharing common ancestry and breed characteristics.
Among breed enthusiasts and owners, these dogs are sometimes affectionately called "ETTs" or "Toy Manchesters," shortened nicknames that reflect their official names while being more convenient for casual conversation. These informal names are commonly used within the breed community and among people familiar with the breed. The dogs' tiny size, elegant appearance, and spirited personality have earned them devoted followings in various countries, with breed clubs dedicated to preserving and promoting their unique characteristics while educating the public about their requirements, temperament, and suitability for various households.
The English Toy Terrier receives recognition from major kennel clubs worldwide, though the specific breed names and classifications vary by country and organization. The Kennel Club in the United Kingdom recognizes them as English Toy Terriers in the Toy Group, maintaining separate status from the larger Manchester Terriers who compete in the Terrier Group. The American Kennel Club recognizes them as Toy Manchester Terriers, classified in the Toy Group but officially considered a size variety of the Manchester Terrier breed. The United Kennel Club, Canadian Kennel Club, and various other national kennel clubs maintain breed registries for these dogs under various names. The Fédération Cynologique Internationale recognizes them as English Toy Terriers, following the naming convention of the breed's country of origin. This universal recognition by major kennel clubs reflects the breed's establishment as a distinct type with devoted followers who appreciate their combination of toy size, terrier personality, elegant appearance, and devoted companionship qualities that make them special among small dog breeds.
