Step 1: Enter Your Dog’s Age in Human Years

    Please ensure the age is a positive number between 0.1 and 30. You can enter the age with up to one decimal place for more precision.

  • Review Calculated Results: Once you’ve entered your dog’s age and selected their size, the calculator will automatically compute the equivalent age in human years using several fields:

    • First Year Equivalent: Displays the human age equivalent for the first year of your dog’s life based on size.
    • Second Year Addition: Displays the additional human years added for your dog’s second year of life, also based on size.
