Watch this excitable dog light up after thinking a mariachi band performing on a street was a special performance for him.

Footage shows Cyrus walking along a street in New York City with his tail furiously wagging after spotting the musicians.

The filmer said: "My dog Cyrus loves to be in big crowds, and he often thinks that they are for him. So when, on the way home from Central Park, we ran into a mariachi band playing for a real estate party on Park Avenue, in Midtown, Manhattan he obviously wanted to join in on the fun and crash the party."
