You know it's a good wedding when the doggo takes over as the main event.

Who doesn't love weddings?

We're not really into race cars and sports, but we are into cute dogs. And this is one of those rare occurrences when these three things intersect in the most beautiful way. Imagine a multi-million dollar budget combined with one of the most scenic venues in the world, and flowers that make the garden of Eden look pale…. but the only thing everyone is talking about is their dog.

Charles Leclerc, prominent F1 driver, finally married his longtime partner Alexandra Saint-Mleux recently and they've released their wedding photos. But who everyone is talking about is Leo Leclerc, Charles's miniature dachshund who showed up in a stunning tuxedo of his own. He walked down the aisle as an honorary groomsman, stealing hearts, and he didn't even go potty once. Way to go, Leo!

Not only did they include him in their wedding, but he made an appearance in nearly every single wedding photo. From selfies with his new mom to editorially gazing out into the sea with the soon-to-be married couple, you can tell that Leo really made this wedding special.

His appearance wasn't just for show; Leo often shows up wherever Charles goes. Since Charles adopted him, Leo has been with him for nearly every important milestone, so it makes sense that he would be pawfectly present during his big day. 

We wish them nothing but happiness, and we're certainly glad Leo is finally getting the stardom he deserves.

  • We recently got married in September of 2025, and our biggest regret was not being able to take our doggo with us. She's quite a bit bigger than Leo, almost 60 pounds! So, we couldn't take her with us to our destination wedding, but we did make temporary tattoos of her so that she would be with us on our big day as well.

  • We're avid fans of the “adopt, don't shop” motto, but if we were to buy a dog, it would be a dachshund. They're just perfect. Silly, tiny enough that you can take on planes without any problem, easy to train, and pawsitively sweet. They're the best kind of dog, in our opinion.
