Serena Williams' Daughter Olympia Flashes Charming Smile While Lying On Her Dog in a Cute Photo

Serena Williams' husband Alexis Ohanian celebrated National Pet Day on Sunday by posting an adorable snapshot of their daughter, Olympia, lying on her dog.

A popular saying goes that a dog is a man's best friend. Serena Williams and Alexis Ohanian's daughter, Olympia, lived out this saying in an adorable picture her father shared on Instagram on Sunday.

Ohanian was commemorating National Pet Day when he shared the cutest snap of Olympia posing on the grass with her dog, Adora.

In the snapshot, Olympia was wearing in Nike print T-shirt and denim shorts which she paired with multi-colored sneakers. She posed lying on Adora who slept on the grass.

Olympia smiled and looked to be enjoying her time with her pet dog. A tennis ball was also beside Adora's mouth. In the post's caption, Ohanian wrote:

"We really don't deserve dogs. Especially big dogs! ❤️Adora #nationalpetday."

The Reddit co-founder's fans commented on the sweet post and agreed with his caption. One fan said dogs are the most precious friends, while another fan said Ohanian's words are true.

Other fans also gushed over Olympia's cute look in the snaps. One fan described her as a beautiful child while another fan said she has the sweetest smile.

Williams and Ohanian have been married since November 2017, and though their union remains solid, it has not been a rosy ride.

Besides spending time with her dog, Olympia loves spending time with her mom and dad, with Williams and Ohanian sharing pictures of their moments with their adorable daughter on social media.

Last week, Williams and the three-year-old posed in matching swimsuits as they stood side by side close to a swimming pool in the backyard of their Florida home.

Williams' swimsuit had "The Shady One" written on it while Olympia's read "The Wild One." In the post's caption, the tennis star wrote that she and her daughter are unstoppable together.

The mother-daughter duo is indeed unstoppable and combined for their first shared fashion campaign for footwear brand Stuart Weitzman, for which Williams is a global brand ambassador.

Williams and Ohanian have been married since November 2017, and though their union remains solid, it has not been a rosy ride. Last month, the mother-of-one admitted that one thing she has learned from marriage is that it is not bliss but can be if one works at it.

Together with Olympia, Ohanian and Williams are one of the cutest families on Instagram, a fact proven by many of their posts on the social media platform, which always leaves their fans asking for more.
