This song was written for the Brokeback Mountain soundtrack so, obviously, it relates to the relationship between the two main characters. I think it has to do with the fact that what they feel for each other is essentially forbidden by the maker (or God) and their society and no matter how hard they try, they can never really be together. So they have to continue living ("get along little doggies") and pretending to be happy ("one more smile I fake").
