How Does the Puppy Age Calculator Work?

The Puppy Age Calculator works by using a formula that adjusts the age based on your puppy's breed size. Puppies develop at different rates depending on their breed size. Smaller breeds tend to age faster early in life and live longer, while larger breeds may grow slower but age more quickly in their later years.

Puppy Age Calculation Formula

The formula to calculate a puppy's age in human years takes into account both their current age in months and their breed size:

  • Small Breed: Puppy Age (months) x 12 ÷ 15 (first 2 years), then multiply by 5.6 after 2 years
  • Medium Breed: Puppy Age (months) x 12 ÷ 14 (first 2 years), then multiply by 6.5 after 2 years
  • Large Breed: Puppy Age (months) x 12 ÷ 13 (first 2 years), then multiply by 7.2 after 2 years

This formula provides an estimate of your puppy’s equivalent age in human years, taking into account breed size and growth stages.
