Dog days of summer, indeed! Gisele Bundchen soaked up the sun with a furry friend on Tuesday, July 29, playing in the sand with her pup, Lua. 

The supermodel, 34, hit the beach in Costa Rica with her family pet, walking the pooch in the sand along the ocean. Bundchen let Lua go off-leash and dip his paws in the water.

The mother to son Benjamin, 4, and daughter Vivian, 19 months, let loose on her dog walk, getting down on all fours to mimic her pooch and have a little fun. 

Tom Brady's wife looked gorgeous on the sunny day, showing off her toned figure in a skimpy swimsuit. She chose a strapless animal print bikini, and shielded her face from the sun in a wide-brimmed hat. 

The stunning model recently celebrated her 34th birthday with her twin sister, Patricia. She and her twin blew out candles on July 20 in front of an ocean background. 

Bundchen shared another vacation snap on Thursday, July 17, showing her doing a cartwheel on the beach in a bikini. "Finally on vacation!" she captioned the shot.
