So just on a whim, I called my mom and asked her to send out his picture and story. And... it WORKED! My mom went and got him last night, gave him a bath and then took him to his new home. It absolutely made my week, and I'm pretty sure it made Cooper's week too :)
He's a 20 pound, one year old corgi mix (look at those short little legs!) and came into the shelter as a stray. He's now set for life with his new family (including two four-legged siblings). I'm hopeful that I'll be able to get some photos of him with them (instead of his shelter mugshot), and if I do, I'll post them here.
