Dogs lifespan: how long do they live and what is the average? Do they live as we do or their life exptectancy is with times shorter?

We all know that dogs are man’s best friend, they protect us, keep us company, feel things sooner than us and make us feel better when we are feeling down.Dogs lifespan, depends on many factors, such as, gender, breed, size, health conditions etc. 

First of all, let’s clear something. 1 dog year is equal to 7 human years.

We all want our dogs to live as much as we do, but, sadly, they dont. Their survival rates are quite low. Dogs lifespan depends on:

  1. Their breed
  2. Lineage
  3. Health condition

So, what is the real dogs lifespan? On average, dogs can live between 6 to 17 years and above. But this is just taken from general statistics, there are dogs who lived more than 17 years. The oldest dog on record was 29 years and five months old.


Dog’s breed has a dramatic influence on your dogs lifespan. There are surveys which suggest that, bigger dog breed live shorter (5 to 6 years) than the smaller one. Some can live more than 17 years while others not even 6. Take a look at this chart to see each breeds life expectancy.

But there are few more things that affect your dog’s lifespan.

  • SIZE

About 40% of small dog breed live longer when compared to bigger ones. The variety falls between 5 and 7 years however, sometimes, it can be over 10 years. Only 13% of the giant breeds live longer, it is so rare. On average, 50-pound dogs live to 12 years, but giant dogs like deerhounds etc. are elderly when they reach their 6th or 8th birthday.

According to a recent research, where over 700 dogs of 77 different breeds were participating, dogs weighing under 30-pounds lived longest. In fact, there is no connection with the height that makes dogs live longer but their weight, which determines their lifespan.

Follows a chart which shows dogs lifespan. It shows dog years to equivalent human years based on the healthy optimal weight of our dogs.

Another factor that determines the lifespan of dogs, beside breed and size, is gender. According to a recent study, female dogs tend to live longer than male.


Maybe this is the most important factor about your dogs lifespan. One breed can have specific health conditions while other breeds could face absolutely different health issues. Cancer is mostly seen in dogs but most commonly in Retrievers, Rottweilers and Boxers, while 1/3 of Bernese Mountain dog breeds die because of cancer.

But, why don’t we focus on the time when our dog is alive in order to live every moment with it. It’s good to live in the present, we feel every moment, we live to the fullest. 🙂
