The term "dog" in the phrase "sign of the dog" has an intriguing etymological background that spans centuries and involves a blend of cultural, historical, and linguistic elements. To understand why this sign is called a dog, one must delve into the rich tapestry of human history and the evolution of language.
The phrase "sign of the dog" is often associated with the constellation Canis Major, which is one of the 48 constellations listed by the 2nd-century astronomer Ptolemy.

This celestial association has been a part of human mythology and astronomy for millennia, with various cultures interpreting the stars in their own unique ways.
In medieval Europe, the term "dog" was used in various contexts to denote something that was common, ordinary, or even derogatory. For instance, the phrase "dog days" refers to the hottest days of summer, when the star Sirius, part of the Canis Major constellation, was visible in the sky. This period was believed to be a time of bad luck and misfortune, further cementing the association of the dog with less desirable attributes.
The use of the term "dog" in the phrase "sign of the dog" can also be traced back to the symbolism of the dog in various cultures. Dogs have been domesticated for thousands of years and have served humans in numerous capacities, from hunting and herding to companionship and protection. In many cultures, dogs are seen as loyal and faithful animals, but they can also be associated with negative traits such as aggression or uncleanliness. This duality in the perception of dogs has likely contributed to the varied interpretations of the "sign of the dog."
Additionally, the term "dog" has been used in various idiomatic expressions and proverbs, further enriching its linguistic and cultural significance.
