These pugs know how to Pawtay! Here is our selection of best pug birthdays for 2017! The pug is our best friend, and these little guys can be with us a long long time. And while these four legged cuties can live super long and happy lives. It's also true that the average lifespan of a pug is from 12-15 years, though I have known a few pugs to live 17-18 years. Lucky dogs! But, their pug birthday will only come about once a year, so you better start planning your celebrations now!
