Not only do dogs have shorter lives than humans, their bodies actually age faster than humans. Different breeds age differently, with small dog breeds in general living longer than large ones. Large dog breeds will have a rate of aging faster than most smaller breeds. A large or giant breed could be looking at a lifespan of only 10 to 12 years. On the other hand, some smaller dog breeds, if kept healthy, can have an additional few years in their average lifespans.
What Causes Dogs to Age Faster Than Humans?
It can be difficult to accept that dogs age significantly faster than us. However, it’s our unfortunate reality, and here are some of the reasons why dogs age faster than humans.
- Size: On average, smaller dogs live much longer than large dog breeds. For example, the average life expectancy of Chihuahuas and Jack Russell Terriers is up to 15 years or even more. However, Great Danes and Irish Wolfhounds have an average life expectancy of around 8 to 10 years.
- Genetics: The genes your dog inherits from its parents play a crucial role in determining its age. Genetics will tell you about the diseases they are prone to and how quickly they age.
- Wear and tear: Dogs love and need – exercise, but overworking your dog can have detrimental effects on their health. Heat exhaustion, muscular pain, and the deterioration of paw pads caused by wear and tear can lead to an early departure for our furry companions.
- Brain: Humans have much larger brains than their animal counterparts. Our brains use a huge amount of energy and take a long time to develop, resulting in a slower journey to sexual maturity. Dogs with smaller brains can grow faster and sexual maturity quickly and breed rapidly in much greater numbers.
Do Dogs Really Age 7 Times Faster?
Contrary to popular opinion, dogs actually don’t age 7 human years for each year in dog years. The long-believed theory: “1 dog year = 7 human years” is not supported by science. According to AKC (American Kennel Club), here is how you calculate dog years to human years:
- 15 human years equals the first year of a medium-sized dog’s life
- Year two for a dog is about nine years for a human
- Each human year would be around five years for a dog
Every dog breed has its own expected life span. Usually, larger dogs live far shorter lives than their smaller counterparts.
How Does a Dog Become Old?

|15||77 to 115|
|20||96 to 120|
Some of the hallmarks of aging in dogs include:
- Greying muzzle

It’s important to note that physical signs of aging might look different in dog breeds.
Help Your Dog Live a Long and Healthy Life
Just like us, age is not a disease for dogs. There are some ways and preventative measures you can take to give your dog a long and fulfilled life.
Here’s how you can help your dog live a long and healthy life:
- Feed the right diet: Feed a high-quality diet that’s specially formulated to provide all the nutrients your dog needs. Give your dog high-quality dog food designed for a specific breed and life stage. This will ensure that your doggie gets all the nutrients they require.
- Give regular exercise: Along with diet, regular exercise is essential for your dog’s overall well-being and can help them maintain a healthy weight throughout their life. This will, in turn, reduce their risk of suffering from potential health problems like heart disease, diabetes, and even arthritis.

By spaying or neutering your dog, vaccinating them, and staying up to date with parasite prevention, you’ll help improve their longevity.
- Schedule regular vet visits: You should be visiting your veteranarian on an annual basis at minimum, and regular check-ups from will help to detect any health issues and hopefully get them treated before they turn into more serious problems.
