Calculate your dog's age
Dog Size
Enter your dog's age and size to reveal the human equivalent.
How to Use This Calculator
Enter your dog's current age and select the size that best matches their build. The calculator applies a size-specific multiplier that reflects the different aging curves of small, medium, and large breeds.
Methodology
Tutti i calcoli si basano rigorosamente sulle formule e sui dati forniti da questa fonte. The human equivalent is derived by multiplying the dog's age by a factor that increases with dog size (small = 5.5, medium = 6.5, large = 7.5) to approximate how quickly larger breeds age.
Source & Formula
Consult the Stoke Vets Pet Age Calculator for the original data references. The basic formula shown to users is:
Glossary
- Dog's Age: The actual age of the dog in years.
- Human Age Equivalent: The dog's age converted to human years via the highlighted multiplier.
Step-by-Step Example
For a small dog that is 3 years old, multiply 3 × 5.5 to approximate 16.5 human years. Larger dogs will convert to higher values per year.
