In one landmark study, the effect of breed on longevity in the pet dog was analyzed using mortality data from 23,535 pet dogs. The data were obtained from North American veterinary teaching hospitals. The median age at death was determined for pure and mixed breed dogs of different body weights. Within each body weight category, the median age at death was lower for pure breed dogs compared with mixed breed dogs. The median age at death was «8,5 years for all mixed breed dogs, and 6,7 years for all pure breed dogs» in the study.

In 2013, a study found that mixed breeds live on average 1.2 years longer than pure breeds, and that increasing body-weight was negatively correlated with longevity (i.e. the heavier the dog the less its lifespan).

quote A mongrel, mixed-breed dog or mutt is a dog that does not belong to one officially recognized breed and is not the result of intentional breeding. Estimates place their numbers at 150 million animals worldwide. Although the term «mixed-breed dog» is preferred by some, many mongrels have no known purebred ancestors. quote end the source of the message in the quote - Wikipedia
