The U.S. Open is one of the biggest tennis events in the world. The annual competition has drawn in millions of viewers over the years, and its popularity is only growing. Both casual and hardcore tennis fans tune in every year to see the best players in the world compete for the coveted prize.

But this fan is a bit out of the ordinary. As it turns out, dogs can be sports fans, too! Check out this adorable tennis lover in action.

No one can deny that dog’s dedication! He’s more of a fan than I am, and I actually understand the sport. I bet Venus and Serena would love to hang out with their biggest four-legged fan.
