Dog age calculator helps to find how old your dog is in human years and also shows interesting facts about your dog's age. This tool takes less than a minute to turn a dog's chronological age into equivalent to your age.
For a long time, people believed that one year for a dog is like seven years for a human. But it's not that simple. Even though this idea has been around for a while, it's not entirely accurate.
Still, many people stick to this rule. Some think it might have started because humans used to live about 70 years, and dogs around 10.
According to Dr. William Fortney, a veterinarian at Kansas State University, explained in the Wall Street Journal, the purpose of this idea was to educate the public about how fast dogs aged compared to humans.
That's a myth. (Reference: Wikipedia.org) Dogs and humans age differently, so one human year isn't the same as seven dog years. But the truth is, dogs age way faster than in the beginning, but then slow down later on.
There's a new way to estimate your dog's age in human years. Scientists studied how DNA changes in humans and dogs as they grow older. They made a formula by which you can easily calculate your dog’s age in human years, such as:
Human Age ≈ 16 * ln(Dog Age) + 31
Where,
ln(Dog Age) – Natural logarithm of the dog's age in dog years.
16 – A scaling factor to adjust dog and human years.
31 – A constant value that adjusts results to the realistic human age range.
Let's calculate the human age approximation for a dog that's 8 years old in dog years using the dog age formula:
Human Age ≈ 16 * ln(Dog Age) + 31".
So, if your dog is 8 years old in dog years, their equivalent human age would be around 64 years old. You can also verify these results from our dog age calculator.
