It looks like the best tennis player in the world is trying his hand at another sport – with his dog! Novak Djokovic missed having poodle Pierre
at Wimbledon, but they're making the most of their down time together!
"I don't know who's having more fun – me or Pierre?" the tennis ace wrote on his WhoSay page
Monday with a picture of his pooch on a surfboard. "He loved it!!! :)"
The Wimbledon champ is enjoying lots of beachside activities on his vacation in the French Riviera with his longtime girlfriend
, Jelena Ristic.
"This is what i do as part of sport activities during my holiday," he wrote with a photo
of him flying a kite. "Quite engaging isn't it? lol"
