Thankfully, living in the foothills of Western North Carolina, we enjoy moderate weather.  The summers aren't too hot and we have our kiddy pools for cooling down and lots of shade trees.  In the winter, we only have a couple of major snows each year.  Boo loves the snow and can play in it for hours before coming inside to warm up in his dog bed.  Everest, Poppy, and Oscar enjoy it for much shorter periods of time.  They will play for a while but they feel the cold a lot sooner.  Daisy and Max are happy to look at it from the inside.  They will go out and do their business but they are going to make it a really fast trip in and out.  Pugs don't do well in extreme temperatures and must have access to heat and air systems.  Pugs can have a single coat or a double coat.  Double coated pugs can withstand temperatures better than single coated pugs.
