This shelter puppys funny habit of cracking a smile has won him hearts, headlines and a new home.

Burreaux the black Labrador pup and his two siblings, Joe and O, were picked up by Humane Society of Northwest Louisiana volunteer Sarrah Walton after the organizations director, Courtney Wingate, spotted the three pups at a kill shelter.

The three dogs had tested positive for parvovirus, a life-threatening gastrointestinal virus mainly affecting young dogs, so they were taken straight to the vet before being brought to the adoption shelter.

Burreaux was very ill, but when he got better, he quickly began to win over Humane Society shelter volunteers with his charming grin.
