“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.
