Pugs are serious lap dogs. My two are happiest when they're with me and somehow making bodily contact. Sunny is generally more laid back, but Rosy has separation anxiety, which was really bad when I first got her. She used to scratch at my door whenever I left (which I did not love) and follow me room to room (which I love). Anytime I leave my apartment now I give them "goodbye treats" in separate corners and then dart out the door as quickly as possible, hoping I haven't forgotten something that'll require a return (accompanied by a major guilt trip from the pugs). That's helped a lot but I know that Sunny and Rosy would still prefer to be with me 24/7 forever and ever.
