Pug, 12-15 years
Pugs are a well-known and popular breed and are known as the ideal house dog. Their breed can be traced back to ancient China some 2,000 years ago when emperors had a thing for flat-faced dogs (like the Shih Tzu mentioned previously).
Pugs are jovial, friendly, and are well suited to apartment living. However, like the Manchester, Pugs are prone to obesity and can suffer a number of other health issues. When taken proper care of and not given too many table scraps, the Pug can still outlive many breeds, living to 15 years old.
