The Invention of the Dog: Exploring Canine History, Evolution, and Enduring Success

A recent episode of The Pawsitive Post in Conversation podcast offered a deep dive into the fascinating world of dog breeds, featuring Tamsin Pickeral, acclaimed author of The Invention of the Dog: 75 Breeds that Changed the World. Hosted by Dr. Zazie Todd and Kristi Benson, the discussion explored the intricate history of canine development, the remarkable success of dogs as a species, and the evolving relationship between humans and their four-legged companions, drawing extensively from Pickeral’s latest, lavishly illustrated work.

Delving into Canine Origins: A Historical Perspective

The journey of the domestic dog, Canis familiaris, is one of the most compelling stories in animal evolution, spanning tens of thousands of years. It is widely believed that dogs diverged from wolves between 20,000 and 40,000 years ago, during the late Pleistocene epoch, an era characterized by vast ice sheets and the presence of Neanderthals. This domestication process, according to Pickeral, likely involved a combination of human intervention and natural selection.

One prominent theory suggests that early humans may have adopted wolf pups, taming and breeding them over generations. However, another intriguing hypothesis, gaining traction through genetic studies, proposes a "self-domestication" model. This theory posits that certain grey wolves possessed genes associated with extreme sociability, leading them to approach human settlements, scavenging for discarded food. Over time, these bolder, less fearful wolves would have gained a survival advantage, gradually evolving into the ancestors of modern dogs. This co-evolutionary path fostered a unique interspecies bond, laying the groundwork for the diverse roles dogs would eventually play in human society.

A pivotal moment in canine history occurred approximately 10,000 years ago with the advent of settled agriculture. As human societies transitioned from nomadic hunter-gatherer lifestyles to established communities with farms and livestock, the utility of dogs expanded dramatically. This shift created new functional niches for canines, driving the selection and breeding of dogs for specific tasks. Dogs exhibiting traits such as aggression were valued for guarding homes and livestock, while those with a natural instinct to herd without harming animals became indispensable to pastoralists. Similarly, specialized hunters, swift sighthounds for chasing prey, and larger breeds for taking down game emerged. This purposeful breeding, driven by human needs and the desire to replicate desirable traits, marked the true beginning of breed diversification. As ancient trade routes developed, facilitating the movement of people and their animals across continents, the intermingling of different regional dog types further accelerated the development of distinct breeds.

The Tapestry of Breeds: Case Studies in Canine Development

Pickeral’s book meticulously chronicles the "true stories" behind 75 breeds, offering insights into their origins and cultural significance. The podcast highlighted three distinct examples, showcasing the breadth of canine history: the elegant Shih Tzu, the robust Bernese Mountain Dog, and the tenacious Yorkshire Terrier.

Shih Tzu: From Imperial China to Global Companion
The Shih Tzu, a breed celebrated for its vibrant personality and luxurious coat, boasts an ancient and regal lineage tracing back to Imperial China. Its origins are documented as early as the Tang Dynasty (618-907 CE), appearing in artworks from that period. However, its deeper heritage is believed to lie with Buddhist monks in Lhasa, Tibet, who selectively bred small, long-haired "lion dogs"—a symbol of strength and courage in Buddhism. These plucky canines, ancestral to both the Shih Tzu and the Lhasa Apso, were frequently gifted to Chinese emperors.

Once in China, these "lion dogs" began to develop distinct characteristics, setting them apart from their Tibetan cousins. The breed flourished within the royal palaces during the Ming Dynasty (1368-1644) and continued to be cherished throughout the Qing Dynasty (1644-1911). A notable patron was Empress Dowager Cixi, a fervent dog breeder who maintained kennels of early Pugs, Pekingese, and Shih Tzus until her death in 1908. The subsequent political turmoil and mass destruction during that era severely impacted these breeds. Fortunately, some were saved, including two Shih Tzus brought to England by Lady Brownrigg, initiating the breed’s re-establishment in the West. From there, the Shih Tzu’s popularity spread to Canada, Australia, and across Europe, eventually leading to its formal recognition as a distinct breed.

Bernese Mountain Dog: Swiss Alps Guardian and Hauler
In stark contrast to the diminutive Shih Tzu, the Bernese Mountain Dog hails from the rugged landscapes of Bern, Switzerland, embodying strength and versatility. Its history spans approximately 2,000 years, coinciding with the Roman invasion of Switzerland. The Romans, known for their extensive use of dogs, brought various types, including large mastiff-like canines, which are considered progenitors of the Bernese Mountain Dog.

Upon settling in Switzerland, these dogs adapted to the demands of alpine farm life, becoming indispensable "all-rounders." The Bernese is one of four Swiss dairy farm breeds—the others being the Greater Swiss Mountain Dog, Appenzeller Sennenhund, and Entlebucher Sennenhund—each prized for its aptitude in guarding, herding, and, most notably, haulage. Bernese Mountain Dogs were particularly adept at pulling small carts laden with milk churns, a testament to their strength and cooperative nature. Beyond their utility, their gentle and affectionate temperament made them excellent companions, contributing to their enduring popularity as family pets today. The breed’s loyal and wise nature was famously highlighted by former Irish President Michael D. Higgins, who frequently brought his three Bernese Mountain Dogs on diplomatic trips, referring to them as "a great source of wisdom" and effective icebreakers.

Yorkshire Terrier: From Mill Ratters to War Heroes
The Yorkshire Terrier, or "Yorkie," represents a comparatively younger breed, emerging in the 19th century amidst the Industrial Revolution in Northern England. Its development is linked to the migration of Scottish miners and mill workers to Yorkshire and Lancashire, who brought their native terriers, likely including early Skye Terriers and the now-unrecognized Clydesdale Terriers. These Scottish terriers interbred with local dogs, leading to the creation of a distinctive breed.

The Yorkie quickly gained recognition for its beautiful, long, silky coat, typically a slate blue-grey and tan, but more importantly, for its formidable character and ratting prowess. In the crowded, rat-infested mills and manufacturing buildings of the era, small yet effective ratters were highly prized. The Yorkie’s ability to dispatch vermin efficiently within confined spaces made it an invaluable asset. By the 1870s, the breed’s concentration in Yorkshire led to its formal naming. A particularly influential figure in its early history was Huddersfield Ben, a champion ratter and prolific stud dog whose genetics are foundational to many modern Yorkies.

The breed’s spirited nature was epitomized by Smokey, a remarkable Yorkie discovered in a foxhole in Papua New Guinea during World War II. Adopted by American serviceman Bill Wynn, Smokey accompanied him on combat missions, notably saving lives by pulling a communication cable through a 70-foot tunnel. Smokey is also recognized as the world’s first recorded therapy dog, providing comfort to wounded servicemen in hospitals in Papua New Guinea and Australia. Her heroism and compassion earned her numerous medals and a memorial, solidifying the Yorkie’s legacy beyond mere utility.

Visualizing Canine Evolution: Art, Photography, and Changing Standards

The depiction of dogs in art provides a unique historical lens into human perceptions and the evolution of breeds. Early representations, particularly in royal portraits, served as status symbols, showcasing the owner’s wealth, hunting prowess, or refined taste. Hunting dogs, in particular, were frequently depicted as a testament to the owner’s social standing. In 16th and 17th-century Dutch paintings, dogs often carried symbolic meanings, acting as moral commentaries or representing fidelity within domestic scenes.

By the 18th and 19th centuries, dogs began to feature as central subjects in their own right, reflecting a growing appreciation for their companionship and individual qualities. The transition from art to photography marked a significant shift in how dogs were documented. While paintings allowed for artistic license and idealized portrayals, photographs offered a more direct, "snapshot" view of a dog’s actual appearance, free from subjective interpretation. This move towards factual depiction, particularly in historical photographs, provides invaluable insights into how breeds have transformed over time.

The formalization of dog breeds in the late 19th and early 20th centuries by kennel clubs around the world led to standardized breeding goals. However, this also inadvertently resulted in significant morphological changes in many breeds. Pickeral highlights stark contrasts, such as the Bulldog, which historically was a more athletic, longer-legged working dog, evolving into the heavier, shorter-legged pet dog seen today. Similarly, the Pomeranian, depicted in Thomas Gainsborough’s 1770s painting "Pomeranian Bitch and Puppy" as a sizable hound, was selectively bred down to its current small, fluffy form, largely influenced by Queen Victoria’s preference for smaller dogs.

These changes, particularly the extreme brachycephaly (flat-facedness) seen in breeds like French Bulldogs, Pugs, and some Shih Tzus, have raised significant animal welfare concerns. These exaggerated features, while often considered endearing, can lead to serious health issues, including respiratory difficulties. The popularity of such breeds is partly attributed to a psychological phenomenon known as "baby schema." Studies suggest that the large, round heads, prominent eyes, and small noses characteristic of brachycephalic dogs trigger an innate human nurturing response, akin to the attraction people feel towards human infants. This subconscious appeal has undoubtedly contributed to their widespread adoption, even as discussions around ethical breeding practices intensify.

The Enduring Success of Canines: Why Dogs Thrive with Humans

Beyond their diverse histories and appearances, dogs’ unparalleled success as a species in coexisting with humans is a testament to their unique attributes. Pickeral emphasizes that dogs are "extremely canny" creatures, possessing profound emotional intelligence and sophisticated communication skills. Their ability to intuit human emotions and respond with unwavering devotion creates an almost irresistible bond. The simple act of a dog wagging its tail or rushing to greet a human evokes a powerful positive response, a connection that few other species can replicate.

Furthermore, canine communication extends beyond body language. Scientific research has identified specific physiological adaptations, such as a facial muscle that allows dogs to raise their eyebrows—a feature absent in wolves. This subtle yet expressive gesture, alongside other communicative behaviors, enables dogs to forge deep emotional connections with humans, eliciting empathy and care. This intuitive understanding, coupled with their trainability and capacity for loyalty, has made dogs indispensable not only as companions but also as therapy animals, medical detection dogs, and invaluable partners in various human endeavors. Their evolutionary trajectory has ingrained a deep-seated ability to thrive in a human-centric world, making them one of the most successful and beloved species on the planet.
