He's only four but he's already a world record holder.
George is the world's tallest dog. He's a Great Dane who lives in Arizona and has just been verified by the Guinness World Records.
They measured him to be 1.09m from paw to shoulder.
He's not a lightweight either - tipping the scales at 111kgs!
Can you imagine having that run towards you?

You know what they say about big paws... Big dog!
