This is hilarious and certainly enhanced by the very fitting sound effects.
I think this should give new meaning to the dog name "snoopy". Maybe even a full name like "Snoopy in yr Poopy".

I doubt this dog was even trained. I'd wager more on the likelihood that he is a reincarnation of the peeper in the first scene of Little Nicky
