Meet Gleason, the adorable, floppy, floof with plenty of pep and a lot of love to offer. Gleason has one of the best tail wags we’ve ever seen here at Muttville, and you won’t want to miss it. The best part? Gleason is dedicated to saving the environment and only uses sustainable fuels like scritches and snacks to power his tail. Thanks for being an eco warrior, Gleason!
