The actor, who is currently promoting rom-com Crazy, Stupid, Love, said that his precious pooch George turns into a nasty piece of work if he doesn’t keep his unusual hairstyle maintained.
Appearing alongside George on Late Night With Jimmy Fallon, Gosling explained his pet’s punk-rock hairstyle.
Gosling revealed: 'He insists on it. Ten years ago I shaved him a mohawk, just for the summer, and then every time it started to grow out, he turned into a total jerk.
“And then I shaved it back and he turned into a nice guy again.'
