How Long Do Dogs Live?

If it were to us, humans, we would make our furry companions live forever. Unfortunately, they can only stick around to chew our shoes for some years. A dog’s lifespan is highly dependent on the breed. However, the size, lifestyle, diet, medical attention, and love, all contribute to it. Before diving deeper into this subject, let’s take a look back at history.

Egyptian pharaohs were buried with their dogs, not just as eternal playmates, but perhaps also because they thought their hounds would come back as puppies. (3) Later in the Middle Ages, these canines most likely kept knights company and begged for scraps under the table. The dogs back then may not have had the longest lives due to these reasons. But fast forward to the 21st century, our canines now live longer and healthier. Thanks to the advancements in vet care and nutrition (probably even to Instagram where some dogs have their own accounts and some of them are even dedicated to Yoga!) 

While the average lifespan of dogs today is about 10-13 years, it varies in dogs of different sizes. Smaller breeds have a longer lifespan, typically in the range of 13-15 years and some even exceeding 18 years. Increase the size and the lifespan drops to 10-13 years for middle-sized dogs. Keep adding inches to their height and width and the lifespan further drops to an average of 8-10 years. Note that all of these are in human years. If we were to calculate these in dog years, the averages would be much higher. (1)

Speaking of higher lifespans, the oldest dog to have ever lived was Bobi, purebred Rafeiro do Alentejo Portuguese dog, who lived for an astonishing 31 years! (The Guinness World Record, however, is on hold currently as there are doubts on the real age. But if it turns out to be true, the age in dog years would be a whopping 170 years!) (2)

Now let’s get on to some breed-specific questions that many of you’ll must have.

How Long do Pitbulls Live? 

American Pitbull Terriers

Pitbulls are one of the most popular dog breeds in the US. They make up nearly 6% of all dog breeds in the country as there are over 4.5 million of them. They are a medium-sized breed that follows the average lifespan of such breeds – 10-14 years.

  • Aortic stenosis

These also form the biggest reasons for their deaths. 

How Long Does a Basset Hound Live?

Basset Hound

They may look like small dogs because of their average height usually being under 15 inches, but they are counted among medium breeds due to their size. These friendly and easygoing dogs live an average lifespan of 12-13 years. 

Their long backs and short legs can be a concern though. Basset Hounds are more prone to obesity because of it. Regular walks and proper nutrition can ensure a healthy life. (5)

How Long Can a Chihuahua Live? 


The average lifespan of the smallest dog breed in the world, Chihuahua, is about 14-16 years. However, some of them have been known to live up to 20 years of age as well. This can be attributed to their tiny size. 

They must be among the longest-living dog breeds, but they are prone to certain medical illnesses during their lifetime. These include – (7)

  • Luxating Patella

  • Dental problems

  • Hypoglycemia

  • Heart Murmurs

  • Cataracts, etc.

 Lack of care when suffering through these can cause their lifespan to reduce significantly.
