Serena Williams, who holds a Miami Dolphins limited partnership with her sister Venus Williams, was having a blast at the Dolphins vs Indianapolis Colts game at Landshark Stadium in Miami on Monday night. But even though the tennis ace loves football, Williams has a better time at events when Jackie, her beloved Jack Russell terrier, tags along.

The pooch was outside in the car with a driver waiting for the game to end. "I take my Jack Russell everywhere," Williams tells PEOPLE. "I am so busy with tennis and my business interests, but I wanted to be at the game to support the team, and Jackie likes to be part of everything I do."
