April 11 was National Pet Day, and Venus Williams was among the many stars who took to Instagram to celebrate their beloved furry friends.


“It’s national pet day and he’s been my puppet for 14 years. I love my Harry! (Harrold when he’s in trouble),” read Venus’s caption.

The seven-time Grand Slam champion also shared a photo of niece Olympia (sister Serena’s daughter) playing with Harry.

“Wow he’s 14???,” Serena asked.

Venus also posted an adorable video of her lip-syncing to Brano Mars’s “Leave Door Open” for Harry.


The Williams sisters aren't the only passionate dog lovers on the WTA Tour. Other pet owners include Aussies Asheigh Barty and Daria Gavrilova, Caroline Wozniacki, Johanna Konta, Amanda Anisimova, Monica Puig, Elise Mertens—among others.
