Walker in the Desert just north of Phoenix

I can't figure out if he's trying to look wise "ah yes Grasshopper, listen and you will learn" or  is it "Man I shouldn't have eaten those chicken legs I buried last month".

A great head shot of Walker, he's starting to look seriously grown up.

Walker at the annual Run for the Cheetahs meeting and greeting the crowd and there is nothing Walker loves more than a baby!

The other dogs were a bit leery of this guy but Walker was facinated.    He needed to figure out if he was man or beast but whatever he was Walker was pretty sure he liked him.
