Dog Age Calculator by Breed

Equivalent Human Age:
0.00 Years


Ever found yourself wondering, "How old is my dog in human years?" You're not alone! The age-old theory that a single dog year equates to seven human years doesn't always hold up to scrutiny. The truth is, a dog's breed and size play a pivotal role in determining their age in human years.

Introducing the Dog Age Calculator by Breed – a groundbreaking tool designed to translate your pooch's age into human years with breed-specific accuracy.

Why is Breed-Specific Age Calculation Important?

Different breeds have distinct lifespans. For instance, smaller breeds like the Chihuahua often live longer than larger breeds such as the Great Dane.

Our calculator is built based on an advanced formula from a research paper in 1997. But we developed that even more.

Researchers at Purdue University’s College of Veterinary Medicine developed a better formula by studying body weight, breed and age at death of over 25,000 dogs. They created this formula:

\text{human age} = (16 \ln(\text{dog age}) + 31)

But in their study, the formula does not include the breed information. It is a blanket-formula for all breeds. So, to fine tune the formula, we included the breed lifespan information and normalized by average lifespan of all types of dogs, which is 12.68 years.

Here is the advanced formula of Dog Age Calculator By Breed:

\text{human age} = (16 \ln(\text{dog age}) + 31) \times \text{breed\_lifespan} / \text{average\_lifespan}

Here, ln is the natural logarithm, breed_lifespan denotes the average lifespan of the chosen breed and average_lifespan is the average lifespan of all dog types.

How to Use the Dog Age Calculator

  1. Select Your Dog's Breed: From the dropdown list, choose your dog's breed.
  2. Enter Their Age: Input your dog's age in both years and months for precision.
  3. Get the Result: Tada! Your dog's estimated age in human years.

Keep in mind, while our tool provides a fascinating and accurate perspective on your dog's age, nothing replaces the advice and expertise of a veterinarian.
