Muttville Senior Dog Rescue presents “Muttsercise!” – a fun senior-dog boot camp day created by Diakadi Fitness!

Watch as the senior dogs work their glutes, pump their biceps and crunch those abs.

Oh wait, it’s the Muttville volunteers doing all the work! What fun!

Muttville saves senior dogs and finds them new families and homes.

Headed to San Francisco? Visit their cage-free HQ and meet some of the residents. You may go home with a gorgeous, new best friend!
