Gromit doesn’t have an officially fixed “real-world” age, but the character does have a birthday and an approximate age range in the canon.

Quick Scoop: How old is Gromit?

  • Gromit’s official birthday is 12 February.
  • The Wallace & Gromit character guides describe him as a young adult dog, roughly “around 20 human years,” which would be about 4–5 in dog years.
  • In practice, his exact age is kept vague so he can stay the same wise, long-suffering “lad” alongside Wallace across decades of stories.

So if you’re wondering “how old is Gromit?”, the most accurate answer is:

He’s a perpetual young adult beagle, officially born on 12 February, with his precise age left deliberately undefined in the series.

A bit of fun context

Fans sometimes try to line up the films’ implied dates and guess that Gromit would be roughly mid-teens to around 20 in human years, based on things like his university graduation and the technology seen around him.

The creators, though, treat him more like a cartoon icon: time passes for us, but for Gromit, it mostly stands still so he can keep rolling his eyes at Wallace forever.
