my favorite dog related dog commerical is the one where a small mixed breed is running hard, chased by a rottie, they go past several people and the rotties gaining ground...the smaller dog jumps into an open car window, the human drives off saying, as the small dog looks out of the window, at the rottie..."i told you she had a boyfriend"...i think it was a car commercial. my favorite cat one was the cat herding one. both can still make me smile
