The dog's loyalty has been refined across millennia of selective breeding and co-evolution. Studies document dogs waiting at owners' graves, travelling hundreds of miles to return home, and maintaining devotion through abuse and neglect that would dissolve any human relationship. The biological basis includes elevated oxytocin response to human gaze and neural architecture specifically adapted for human social cues. A dog's loyalty requires no narrative justification; it exists as pure, unearned devotion. The species has demonstrated willingness to die for humans with such regularity that it no longer constitutes news.

The domestic dog has accompanied humanity for a minimum of 15,000 years, with some evidence suggesting 40,000 years of co-evolution. Dogs survived ice ages, agricultural revolutions, industrialisation, and the digital age whilst remaining humanity's preferred companion animal. The species demonstrates extraordinary adaptability to changing human needs—from hunting partner to therapy animal. Barring catastrophic extinction events affecting both species, the human-dog bond shows every indication of perpetual continuation. Dogs were here before recorded history; they will likely outlast any specific cultural product.

Dog accessibility varies considerably by geography and circumstance. Acquisition costs range from free to thousands of pounds for pedigree breeds. Ongoing costs include food, veterinary care, insurance, and housing modifications. Rental restrictions exclude millions from ownership. Allergies affect approximately 10-20% of populations. Travel with dogs requires planning; employment with dogs remains unusual. The benefits of canine companionship are thus gatekept by economic circumstance, housing situation, health status, and lifestyle. Not everyone who wants a dog can have one.

Dogs have shaped human civilisation across every domain: hunting, herding, guarding, warfare, policing, disability assistance, search and rescue, and companionship. They appear in mythology from Cerberus to Anubis, in art from cave paintings to Instagram. The dog industry generates over $100 billion annually in the United States alone. Dogs have altered human settlement patterns, influenced architecture, and restructured daily routines. The phrase 'man's best friend' requires no explanation in virtually any language. Dogs are not merely culturally significant; they are civilisationally constitutive.

Canine emotional support operates through multiple verified mechanisms: physical contact reduces cortisol and elevates oxytocin; the requirement for walks imposes exercise and routine; responsibility provides purpose during depression; and the dog's apparent emotional attunement creates perception of understanding. Clinical studies demonstrate dogs reducing anxiety, depression, blood pressure, and loneliness with statistical significance. Therapy dogs now operate in hospitals, disaster zones, and universities. A dog cannot judge your career failures, relationship collapses, or 3 a.m. biscuit consumption. It offers presence without evaluation.
