Marmaduke falls in love with the popular girl and [[ObliviousToLove doesn't realize his female friend loves him,]] check. Marmaduke becomes popular and abandons his friends, check. The other dogs [[LiarRevealed figure out Marmaduke lied and abandon him,]] check. Meanwhile the dad is going through his own plot about how he should [[WhenYouComingHomeDad work so much and he needs to spend more time with his family.]] And this doesn't even [[UpToEleven cover all of it.]]
