Dog Age Calculator
Convert your dog's age to human years with our accurate calculator
Dog Details
Age Adjustment
For medium dogs, we calculate 5 human years per dog year after age 2. The first year equals 15 human years, and the second year adds 9 more.
The traditional "multiply by 7" rule is an oversimplification. In reality, dogs age more rapidly during their first two years of life compared to later years.
Our calculator uses a modern approach that accounts for:
- The first year of a dog's life equals about 15 human years
- The second year adds 9-11 more human years (depending on size)
- Subsequent years add 4-7 human years each (depending on size)
- Size is a significant factor in aging rate (smaller dogs generally live longer)
Important Note
This calculator provides an estimate based on current research. Individual dogs may age differently based on genetics, health, and lifestyle factors. Regular veterinary care is the best way to monitor your dog's health as they age.
