About Dog Age Calculator
Convert your dog's age into human years using our Dog Age Calculator and better understand your furry friend's life stage.
What is a Dog Calculator?
The Dog Calculator is a tool that helps you convert your dog’s age into human years. Unlike the simple rule of multiplying by 7, our calculator uses breed-specific and age-specific formulas to estimate your dog’s equivalent age in human terms. It’s a fun and insightful way to understand your pet’s development and life stage.
How to Use the Dog Calculator
- Select your dog’s age in years.
- Choose your dog’s breed size (small, medium, or large).
- Click on the "Calculate" button.
- Get your dog’s equivalent age in human years instantly.
Dog Age to Human Years Formula
The dog-to-human age conversion isn't linear. Dogs age rapidly in their first two years and then at different rates based on their size:
- Small breed (under 20 lbs): Human Age = 15 + (Dog Age - 1) × 4
- Medium breed (21–50 lbs): Human Age = 15 + (Dog Age - 1) × 5
- Large breed (51+ lbs): Human Age = 15 + (Dog Age - 1) × 6
This provides a more realistic conversion based on veterinary research.
Example Calculation
Dog Age: 5 years
Breed Size: Medium
Result: 15 + (5 - 1) × 5 = 15 + 20 = 35 human years
