Eh, no idea, got her from the shelter but a quick google search shows that main coons do look an awful like she does... Probably a mix of Main Coon and something else. As for friendliness, well.... thats debatable.
She is a bit neurotic, hates other animals and is not a big fan of strange people. However if you sit down in her area she will hop up and curl up in a furry ball on your lap and refuse to leave until you stand up, and only when she is almost dumped onto the floor.
As for my experience with Pugs, not very much. But when my sister was in college her roommates had two Pugs. They were some of the most energetic dogs I have ever met. I dont think they sat still for 10 minutes.
