"This Old Dog," the eponymous single from Mac DeMarco's upcoming album, is a request for loyalty despite personal failings. Actual dogs are best at this, so perhaps that's why Crack Magazine filmed Mac playing an acoustic version of the track in a dog grooming salon. The pups don't pay much attention, but if you were a fan of the original version, this new spin highlights its vulnerability and pretty melodies. Good boy, very good boy. Watch above. Mac DeMarco's new album This Old Dog is out May 5.
