Parents need to know that Marmaduke is mostly inoffensive, unless your family detests potty humor, in which case this isn't the movie for you. The main issue with any talking-animal flick is the degree to which the animals are stand-ins for humans, and in this case, the animals are made to seem like high-schoolers with all their accompanying social and romantic drama. There's a lot of romantic pining and even doggie dating and flirting, which may go over the heads of kids too young to understand the nuances of romance. Some subtle drug references pop up that will also bypass the kids' radar. The language is limited to insults like "freak," "stupid," and "loser," and mimics the bullying and teasing you'd find in a movie about unpopular students. For such a short movie, there are several positive messages about the importance of honest, unconditional friendship and family versus work time -- not that they'll necessarily get noticed with all the dog-fart jokes in the way.
