Why is the post office sign called a dog? - in detail
The term "post office sign" being referred to as a "dog" is an intriguing historical and linguistic curiosity that has evolved over centuries. This unique moniker can be traced back to the early days of mail delivery, particularly in England during the 18th century.
During this period, the British postal system was undergoing significant changes and expansions. One of the innovations introduced was the use of signs to indicate the presence of a post office. These signs were often depicted as a dog, specifically a greyhound or a mastiff, standing on its hind legs with a post horn in its mouth. The choice of a dog for these signs was not arbitrary; it held symbolic significance.
The dog, particularly the greyhound, has long been associated with speed and reliability, qualities that were highly valued in the context of mail delivery. In medieval heraldry, the greyhound often represented swiftness and agility, making it an ideal emblem for a service dedicated to the efficient transfer of information. Additionally, dogs have historically been seen as loyal companions, further emphasizing the trustworthiness and dependability of postal services.
Over time, these signs became so ubiquitous that the term "dog" began to be informally used to refer to any post office sign, regardless of its actual design. This usage was not limited to Britain; as the British postal system expanded globally through the establishment of colonies and the spread of imperial influence, the term "dog" also traveled with it.
In conclusion, the colloquial use of "dog" to refer to a post office sign is rooted in historical tradition and symbolism. It reflects an enduring connection between speed, reliability, and the essential service that post offices provide. This linguistic quirk serves as a reminder of the rich history behind modern postal systems and the enduring power of symbols in shaping our language and culture.
