Yorkshire Terrier

Yorkies live on average 14 to 16 years. Don't let the look of these feisty terriers fool you. While this popular breed is often pampered today, people used their ancestors to hunt rats.  Little dogs tend to live a lot longer than larger breeds. Big dogs, it seems, just age faster. It may be because they have more growth hormones.

Shetland Sheepdog

Farmers raised these dogs to herd animals on the Shetland Islands near Scotland. Because of their small size, they ate less and lived longer than other dogs. Today’s Shelties usually live 12 to 14 years. Pay attention to their teeth, which are prone to infections that can lead to kidney failure.

Labrador Retriever

Labs are the most popular breed in America. Fortunately, they’re also one larger-sized breed that lives a long time -- on average, 10 to 12 years.

The Chihuahua, the smallest recognized breed, traces its roots back to the 9th century. Their ancestors were beloved by people of Central America. The mighty mites live as long as 14 to 18 years. Bred in warm climates, Chihuahuas don’t do well in the cold. Given their small size, they may not be the right breed for young, active kids.

Mixed breeds

Mixed-breed dogs live an average of 14 years. Overall, purebreds live an average of nearly 10 years. The difference may be because dogs bred to meet standards sometimes pass along problems in their genes, too. It’s hard to predict how long a mixed-breed dog will live, but your mutt is certain to be one-of-a-kind and probably a lot less expensive!
