Whats my dog thinking about?

i have 6 dogs, 1 blue healer beagle mix that showed up @ the shop one day as a stray and 5 bassets. 2 of the bassets were ours and the other 3 were given to us from people that didn't want them any more. one of the male dogs name is Buster, i think he is a goofy ass dog! but like most dogs, they look at you like your their hero! what i find funny about buster is he always has a goofy ass look on his face! i always get a laugh watching him! just like when he takes a crap in the yard! after he's done doing the dirty and building a mountain steaming stink he pulls forward & stops and proceeds to start peeling out! I'm talking grass flying in the air like a weed eater in a brush pile. i always wonder what the satisfaction in doing this is? after i take a big crap i never stand up and peel out throwing the floor mat all over the toilet, but what ever the satisfaction it makes buster pretty happy!
having 6 dogs means finding a place to crap can be a chore! and crapping on one of the many walking trails around the yard is a doggie no no! yet every once in a while someone slips and lays a log on the walking path! i saw buster walking across the yard on the clear walking path and he comes across someone else's turd! the look on his face was priceless! like he had never seen a dog turd before! he takes a sniff then looks around the yard with a pissed off look on his face! i can imagine him saying to himself! who crapped on the walking trail! he starts to walk around the turd and then he looks around the yard to see if he can spot the culprit! too funny!
i have though about sneaking out in the middle of the night & taking a big crap in the yard just to see the reaction of buster!
