Our calculator uses different formulas for dogs and cats based on veterinary science research:
For Dogs: The first year equals approximately 15 human years, the second year equals about 9 human years, and each additional year equals around 5 human years. We've also incorporated breed size adjustments as smaller dogs tend to live longer than larger breeds.
For Cats: The first year equals approximately 15 human years, the second year equals about 9 human years, and each additional year equals around 4 human years. Cats mature quickly in their first two years but then age more slowly.
These formulas provide a more accurate representation of your pet's aging process compared to the old "multiply by 7" rule.

Frequently Asked Questions
How accurate is the dog years to human years conversion?
Our calculator uses the most widely accepted conversion formula: 15 human years for the first year, 9 years for the second year, and about 5 years for each additional year. This provides a good general estimate, though breed size can affect aging rates. Smaller dogs tend to live longer and age more slowly than larger breeds.
Do cats and dogs age at the same rate?
No, cats and dogs age differently. Cats mature slightly faster in their first two years but then age more slowly than many dogs. Our calculator uses different formulas for cats and dogs based on veterinary science recommendations. Generally, cats have longer lifespans than most dogs when properly cared for.
Why does breed size matter for dog age calculation?
Smaller dog breeds tend to live longer and age more slowly than larger breeds. Larger dogs mature faster and have shorter lifespans. Our calculator includes breed size options for more accurate dog age calculations. For example, a 7-year-old Great Dane would be considered quite senior, while a 7-year-old Chihuahua would still be in its prime.
