Meaning and background
The story behind Billy
Billy began as an English familiar form of Bill, itself a shortening of William. Unlike many newly invented pet nicknames, it has a verifiable history as a personal name, with a recognisable two-syllable pronunciation. Behind the Name records historical bearers such as Billy the Kid and the musician Billy Joel. None of those references determines why an individual dog is called Billy, but the human-name connection is secure.
