I also have 2 pugs, they are brothers and are just over 2 years old. One is still very hyper but listens really well and the other is a bit more layed back but is pretty stubborn when it comes to listening.
They do shed a lot but I try to keep up with their brushings and it is not that bad.
Heat and cold does affect them quicker so always keep a close eye on that.
I love to tell them that they are so darn ugly that they are cute because lets admit it, those faces are kinda strange looking lol
I think you are going to love your new puppy and maybe even get a 2nd!
