Leo is Leclerc and Saint Mleux's little dachshund. On Formula 1 race weekends, when Leclerc is racing, Leo is often found in and around the Ferrari garage. Both Leclerc and Saint Mleux adopted Leo in April 2024.

In an interview with GQ Sports, Leclerc shared what Leo means to him: "He's my best friend. He's the best. I bring him to most of the races. Last year, he did get a paddock pass, but he doesn't need it anymore. People know him more than me. He can still get into the paddock at every race he comes to."

Leclerc shared that Leo's favorite toy is a squeaky pink dinosaur, adding, "He loves it. This noise is his favorite in the world. He gets very excited."

As exciting as the racing is, one fan in particular devotes their time to running an Instagram fan page dedicated to Leclerc and Saint Melux’s furry friend.

As of November 2025, the account has 194k followers, reflecting the huge demand for content of him enjoying his luxurious lifestyle.
