(CNN) - A smiling Chihuahua named Cheech may have taken the cake for cuteness with his merry mug.
Cheech was a recent resident of The City of Waller Animal Shelter and Rescue in Texas.
His toothy grin made him a viral sensation after the shelter posted photos of him on Facebook and were shared thousands of times.
His charming chompers also helped him land a new home.
Rescue shelters nationwide take in more than 6.5 million animals a year. The ASPCA estimates that only about 3 million are adopted annually.
While not all shelter animals can be as charming as Cheech, they still need good homes.
