Loyalty is often the first word people associate with dogs—and for good reason. For thousands of years, dogs have lived alongside humans, serving as hunters, guardians, herders, and most importantly, companions. Their loyalty isn’t just a personality trait; it’s rooted in evolutionary biology.
Research published in Science revealed that when dogs and humans gaze into each other’s eyes, both experience a release of oxytocin—the “bonding hormone” that strengthens trust and emotional connection (1). This neurological link explains why certain breeds are exceptionally loyal, protective, and deeply bonded to their families.
