This pup took his job seriously. He didn’t bite, but he growled until that guy stepped back.
Hey everyone! I have a twitter feed now! Follow me, @dogsofsf, for occasional updates with pictures of dogs that I run into that I don’t have time to do a full photo-shoot for, just quick snaps on my iPhone. Also pictures of random city stuff that I run across.

He does look like he takes his job seriously, but I can’t help but thing a slightly bigger dog might be a better deterrent.
