His quirky smile has already accomplished quite a bit for him and his siblings; Burreaux was originally living in a kennel managed by animal control when Courtney Wingate spotted the smiley pup.

Wingate is the director for HSNWLA and when Burreaux gave her a big smile she knew that she had to bring the charming pup and his siblings with her to the rescue centre. She was determined to find them all good homes.

But before Burreaux had even had a chance to readjust to his new life at the rescue centre, he got sick and had to be taken to the animal hospital. Thankfully, he recovered from his health scare and was eventually able to properly settle in at the rescue with his brother and sister, Joe and O.

Burreaux didn’t let his little set back get him down and once he was safely back at the shelter, he was all smiles – literally. Whenever anyone looked his way or spoke sweetly to him, he would flash them his biggest, goofiest grin.

His big, toothy smile has proven downright infectious and it’s now melting everyone’s hearts.

Burreaux’s brother, Joe, has already found his forever home. When the pups were ready to start looking for their forever families, the shelter posted a video featuring Joe playing fetch and he immediately won a lucky family’s hearts.

Inspired by Joe’s success, the shelter decided to showcase Burreaux special talent: his unique smile! They shot a video of Burreaux grinning at the camera and, after posting it online, the video soon went viral.

We’re sure that with all the attention Burreaux’s endearing smile has brought himself and the shelter, he and his sister will soon find their own perfect forever homes.
