Aside from being absolutely adorable—and the ideal posterboy for #TongueOutTuesday—Mervin is a champion for second chance pups everywhere.

Initially found as a stray and brought to the ASPCA, Mervin, a very special-needs dog, has made a major splash all over social media.

After being properly nourished, undergoing knee surgery, and having all of his teeth removed—it's soft food for life—he was adopted by Joey, a kind man who works at the ASPCA in New York City.

Now, the five-year-old chihuahua is happy as a clam and hamming it up for the camera, showing us all just how much of a difference a little TLC can make.

Together, Joey and Mervin are on a mission to show support against animal cruelty and to promote the adoption of dogs.

With 30K followers on Instagram alone, we suggest you take a look, if you want to have your entire day made and then some.
