My daughter's German Shepherd dog, Zoso, is no longer a 3-month old puppy, but he's still got a lot of pup in him!  He's now 17 months old and has received his certificate for passing Dog Obedience school.  And he did a great job!  Here's an adorable video of Zoso learning how to sit, shake a paw, and lay down.  [Watch]  #adorablepuppy  #goodpuppy
