Do Mixed Breeds Live Longer Than Purebred Dogs? – Dogster


Most pet parents have likely heard the theory that mixed-breed dogs live longer and are healthier than purebred dogs.

Do mixed-breed dogs live longer?

While there’s some research supporting the theory that some mixed breeds could live longer, it’s not a simple answer.

Dr. Annette Louviere, of Wisdom Panel pet DNA testing service, says that a recent study by the University of California, Davis and Wisdom Panel found that breeds with higher in-breeding require more veterinary care. It also found that after removing brachycephalic breeds from the analysis, larger breeds in this category tend to require even more health care than smaller-sized breeds. And typically, breeds with the lowest amount of in-breeding came from randomly-bred backgrounds (mutts) or breeds with recent cross-breeding (like the Australian Labradoodle).
