Marmaduke is wearing a pair of specially-modified dog skis on his daily walk through his neighborhood, where it has recently snowed. His owner-lady pleads with him not to get carried away and attempt any dangerous maneuvers, but truth be told, Owner-Lady forfeited any and all rights to her own physical well-being the moment she allowed herself to be dragged behind a monstrous Great Dane on skis who lives to torment and humiliate her. The shit-eating grin on Marmaduke's face indicates that fancy slalom stuff was a foregone conclusion.
