The term "dog" in reference to the mailbox icon is a colloquial expression that has its roots in the early days of computer interfaces and has evolved over time to become a widely recognized term. The origin of this term can be traced back to the early graphical user interfaces (GUIs) developed in the 1980s and 1990s.

The mailbox icon, which is often depicted as a small envelope or a letter, was chosen to visually represent email or messages.

However, in many tech circles, particularly among developers and early adopters of computer technology, the term "dog" has become a recognized and accepted way to refer to the mailbox icon.
In summary, the mailbox icon is often colloquially referred to as a "dog" due to its association with the concept of a watchdog or guard dog, which monitors and alerts users to new messages.
