10 years is the life span of pugs. They mostly live a sedentary life which is prone to obesity. They usually have a wrinkly and curled tail. Check out http://en.wikipedia.org/wiki/Pug for more information.
I'm sorry, but you guys are all wrong. The lifespan of a pug is up to 16 years. They are sedentary but genetically they are created for that lifestyle. As long as their airways are protected during hot and cold weather, and you keep their weight reasonable, they have quite long lifespans. I've have one live to 16 and one 15.5.
