Baseball's hot dog!

29 June 2017 Last updated at 08:20 BST

Meet Jake the Diamond Dog who helps out at baseball games in America.

For years he's been helping to keeping everyone cool at minor-league baseball stadiums.

Jake brings bottles of water, fetches dropped bats and waits patiently for the umpires to finish before exiting the field.

And sometimes he even gets a game of frisbee!

Take a look at Jake in action.
