just wondering.....

    

does anyone else's dog just randomly decide to put their paws on your body, stand straight up, and take a deep stretch? normally, yuki and rocket do this after they've been sleeping in their kennel for a while. when we let them out, they coming running towards us and then do this stretch on our bodies.  this stretch however, took me by surprise. i was trying to take a picture of the front door, since it's part of a thing i'm doing for instagram (picture a day), and he did this stretch out of nowhere. i was also wondering if anyone knows if there's any wolf-instinct connection here. i know they do the 'dig and circle' thing before they sleep, because their wolf-instincts tell them to make their imaginary bed from grass. i thought maybe there could be something about this someone might know???
