Dog Age Calculator
The dog age calculator will find the answer to the most common question a dog owner asks: how old is my dog in human years? 🐕
There's no simple way to accurately convert dog to human years since each dog year is not equivalent to one human year. Spoiler: one dog year is not equal to seven human years either.
The relationship is non-linear (like in exponential growth). That's why you need either a dog year calculator or a dog years chart.
Luckily, we have both. With this tool:
- Know how old is 13 in dog years;
- Find how many dog years is one human year;
- Convert any number of dog years to human years; and
- Find exactly the conversion between a labrador dog years and human years based on research.
How to use the dog age calculator
The dog age and human years conversion varies by breed and size. No formula covers every case.
Generally speaking, small breeds live longer. This tool aims to be as precise and general as possible and lists three options for you to input information about your dog:
- Small size.
- Medium size; and
- Large size.
Just input your dog's size and age, and the calculator will do the rest! You can also check the dog age chart below.
🙋 Even though there are some cases of dogs living longer, you can only input years lower than 20 in the dog age field to keep the conversion accurate.
Dog age chart/table
You can also manually find how old your dog is in human years by searching it in the dog age table:
Human Years (Small)
Human Years (Medium)
Human Years (Large)
For example, if we want to find how old is 13 in dog years, we can seek the values in the table for each dog size. Here we find that 13 dog years is equal to:
- 68 years for a small dog;
- 74 years for a medium-size dog; and
- 82 years for a large dog.
We all want to keep our dogs in comfortable conditions like appropriate temperatures or air humidity. The latter is described in detail in the. Be sure to check it!
In our dog age calculator, we have included a scientifically proven formula for calculating the age of the Labrador breed.
You can read more about this formula and the research behind it in the paper written by the team led by Trey Ideker from the University of California, San Diego called ''.
