Didn't want to derail the "name the pug" thread by being unfriendly but I don't get the attraction. They are overbred to the point of being disastrously unhealthy from everything I've read and seen.
My daughter (6) loves them (sadly for her, we have the extreme opposite - a greyhound!) but I have told her we will never have one as the vets' bills would be sky high.
