The Old English Sheepdog's history spans approximately 200 years, making it a relatively young breed compared to many ancient working dogs. The breed's exact origins remain somewhat mysterious, with documentation scarce before 1771 when English artist Thomas Gainsborough included what many believe represents an early Old English Sheepdog in a painting. This early depiction shows a small, drop-eared dog with shaggy coat characteristics, though the dog appears less substantial than modern representatives. Historical evidence suggests the breed developed in the southwestern counties of England, particularly in Devon, Somerset, and Sussex, where farmers needed versatile dogs capable of driving cattle and sheep to market across considerable distances.
The breed's development likely involved contributions from several European herding breeds. Most fanciers agree that the Bearded Collie played a significant role in the Old English Sheepdog's ancestry, contributing herding instinct, coat type, and working temperament. Other theories suggest crosses with the Russian Owtchar, Scottish Deerhound, Briard, Bergamasco, and possibly the now-extinct Smithfield or Cotswold Cor, a bobtailed drover's dog noticed in southwestern England during the early 19th century. These crosses would have combined to create the distinctive appearance, substantial bone, profuse coat, and working ability that characterize the modern Old English Sheepdog.
The breed's original purpose centered on driving rather than traditional herding. Drovers needed dogs capable of moving livestock—particularly cattle and sheep—long distances from farms to urban markets. Unlike herding dogs that gather and control livestock in pastures, drovers' dogs walked alongside herds, keeping animals together and moving forward, sometimes covering many miles daily. This work required stamina, weather resistance, independence, courage to face down obstinate cattle, and the intelligence to make decisions without constant handler direction. The breed's substantial size, protective coat, and steady temperament all developed to meet these demanding requirements.
The bobbed tail that gave the breed its Bobtail nickname arose from British tax law rather than natural mutation. During the 18th and 19th centuries, working dogs with docked tails qualified for tax exemptions, as the docked tail served as visible proof of working status. Drovers routinely docked their dogs' tails to avoid taxation, and the practice became so associated with the breed that Bobtail became synonymous with Old English Sheepdog. Some dogs were born naturally with short or absent tails, and breeders sometimes selected for this trait, though most tails were artificially docked in puppyhood. Modern regulations in many countries prohibit cosmetic tail docking, so undocked Old English Sheepdogs with long, profusely feathered tails are increasingly common.
The breed's coat served multiple practical purposes beyond weather protection. Farmers traditionally sheared their Old English Sheepdogs each spring when sheep were shorn, using the dogs' wool to make warm clothing, blankets, and other textiles. The harsh-textured outer coat and soft, waterproof undercoat provided insulation in cold, wet English weather while the shaggy texture resisted matting during hard work. The coat also offered some protection from aggressive livestock and harsh vegetation encountered during droving work.
The breed's transition from working drover to show dog and companion began in the mid-19th century. The first Old English Sheepdog appeared at a dog show in Birmingham, England in 1873, with only three entries. The judge found the quality so poor that he awarded only second place, believing none of the dogs deserved first. Despite this unpromising beginning, dedicated fanciers recognized the breed's potential and began systematic breeding programs emphasizing consistent type, sound temperament, and working ability. The breed's popularity grew rapidly among the wealthy, who appreciated the dogs' distinctive appearance and gentle nature.
The Kennel Club of England recognized the Old English Sheepdog in 1873, and the first breed standard was written in 1888. American interest in the breed developed during the 1880s when wealthy industrialists and prominent families imported the best English breeding stock. William Wade of Pittsburgh promoted the breed extensively, and by the early 1900s, five of America's ten wealthiest families—including the Vanderbilts, Guggenheims, and others—bred and showed Old English Sheepdogs. This high-society connection ensured quality breeding programs and substantial financial support for breed development.
Henry Arthur Tilley and Freeman Lloyd, both Englishmen with extensive breed knowledge, founded the Old English Sheepdog Club of America in 1904, which gained AKC recognition in 1905. These founding members possessed complete understanding of the breed's working heritage and established standards emphasizing soundness, proper structure, and stable temperament. The Tilley family's Shepton Kennels influenced the breed for over a century, with many modern pedigrees tracing back to their dogs. Early American breeding emphasized the working dog's moderate size—17 to 23 inches and 45 to 60 pounds—quite different from some modern dogs.
The breed's popularity surged during the 1960s and 1970s, driven by media appearances including Disney's The Shaggy Dog, television shows, and Dulux paint advertisements featuring the breed as their mascot. This exposure brought the Old English Sheepdog into public consciousness but also attracted less responsible breeders capitalizing on popularity without regard for health, temperament, or proper breeding practices. Annual registrations reached approximately 15,000 dogs during the mid-1970s, but many new owners were unprepared for the extensive grooming requirements and the breed's need for exercise, training, and companionship.
Reputable breeders have worked diligently to restore breed quality and educate the public about the realities of Old English Sheepdog ownership. Modern breed clubs emphasize health testing, particularly for hip dysplasia, eye disorders, and other genetic conditions. The breed's numbers have decreased from the 1970s peak as prospective owners become more educated about grooming demands and care requirements, but this reduction has generally benefited the breed by reducing indiscriminate breeding. Today's Old English Sheepdog remains true to its herding heritage while serving primarily as a beloved companion, show dog, and competitor in various dog sports including herding trials, obedience, agility, and rally.
