Why Spencer rocks

I took Spencer over to Scott's last night so that Spencer and Pippin could play.  They played very well for a couple hours, and both seemed to be getting along nicely.  I was highly amused/proud of my pup though when he was happily chewing on his (well, he stole it from Pippin) bone, when Pippin decided he wanted to get my attention by jumping up on me.  Well, Spencer wasn't going to have any of that.  He put the bone down, stood up, walked over to Pippin and started "laying the smack down."  Within seconds, Pippin was laying on the floor, upside down, with Spencer's mouth around his throat.  I couldn't help but smile :)
