In heraldry, the dog is a respected symbol of loyalty, vigilance, courage, and faithful service. More than almost any other domestic animal, it represents steadfast attachment to a master or cause, which is why it often appears in arms connected with guardianship, hunting, military duty, or personal fidelity. A dog charge can suggest not only affection and trustworthiness, but also alertness, obedience, and readiness to defend what is valued. In that sense, the heraldic dog is both a companion and a watchman, combining devotion with strength of purpose.

Heraldic usage often treats the dog specifically as a hound, and several types appear in armory, especially the talbot, greyhound, and other hunting dogs. These variations could sharpen the meaning of the charge. A talbot often conveys endurance, scent, and dependable pursuit, while a greyhound adds speed, elegance, and noble bearing. Dogs may be shown passant, courant, sejant, rampant, or collared, depending on the tradition and the story the arms are meant to tell. In medieval and later heraldry, such figures were particularly suitable for families associated with hunting, landholding, wardship, or honorable service, and they remain among the clearest symbols of fidelity in armorial design.

For reliable background, see Hound (heraldry) on Wikipedia, which outlines the main heraldic types and attitudes, and Mistholme’s Dog entry, which gives useful historical notes on talbots, greyhounds, and alaunts.

Together, these sources show why the dog remains a powerful heraldic emblem of loyalty, noble service, watchfulness, and disciplined courage.
