I'm the official `Welcome Wagger` of the shelter!With my brown and white coat and a grin that can brighten even the cloudiest day, I'm pretty sure I've got a shot at winning that smiling contest someday. But here's the thing, I'd rather win your heart and become your lifelong buddy. Let's make each other smile every day!So, what do you say? Come on down for a meet and greet, and let's create some paw-sitive memories together. I promise to bring endless laughter, tail wags, and all the love you can handle.
