I know I've said this before, but pugs really have no concept of personal space. And I love it! Pugs were bred as lap dogs but my two don't just stop there. They are all up in my face, sitting on my shoulders, resting on my feet, bumping their faces against my legs, tripping me everywhere I go. Rosy especially will follow me everywhere from room to room, and sometimes even when I just go across the same room.
If you like dogs that give you space and aren't needy, then a pug is not for you. But if you love the idea of having a little furry barnacle with you at all times, then a pug may very well be for you!
