This next breed might surprise you! Yes, mixed breeds are one of the longest living dog breeds. Purebred dogs carry genes down their bloodline that have the potential to result in health problems while a mixed-breed dog, affectionately known as a mutt, doesn't. Instead, his genetic make-up varies.

Since Pomeranians only weigh between three and seven pounds, we can deduce that, like chihuahuas, they will have longer life spans. They live on average anywhere from 12 to 16 years, and are known to be sharp and perky throughout their lives.

While pugs can carry their fair share of respiratory problems due to their flat-faces, they still live long, happy lives. Remarkably, they can live up to 15 years. Since pugs are prone to obesity, you can boost a pug's life longevity by keeping him fit and well fed. Try incorporating fresh fruits and vegetables, like blueberries, instead of treats.
