Formula / Working

The Dog Age Calculator uses a formula based on canine development, which varies slightly by size and breed. A common method for medium-sized dogs is:

1. The first year of a dog’s life = 15 human years.
2. The second year = an additional 9 human years.
3. Each year thereafter = 5 human years (small dogs) or 6 human years (medium dogs) or 7 human years (large dogs).

General Formula: Human Age={1 dog year=15 human years2 dog years=24 human years3+ dog years=24+(dog age−2)×X\text{Human Age} = \begin{cases} \text{1 dog year} & = 15 \text{ human years} \\ \text{2 dog years} & = 24 \text{ human years} \\ \text{3+ dog years} & = 24 + (\text{dog age} - 2) \times X \end{cases}Human Age=⎩⎨⎧​1 dog year2 dog years3+ dog years​=15 human years=24 human years=24+(dog age−2)×X​

Where X = 5, 6, or 7 depending on the dog’s size. This formula helps translate your dog’s age into human terms, providing insight into their maturity, health risks, and care needs.

Examples

Example 1:
A 1-year-old dog: Human Age=15 years\text{Human Age} = 15 \text{ years} Human Age=15 years

Your puppy is roughly the equivalent of a 15-year-old teenager in human years.

Example 2:
A 3-year-old medium dog: Human Age=24+(3−2)×6=30 years\text{Human Age} = 24 + (3-2) \times 6 = 30 \text{ years} Human Age=24+(3−2)×6=30 years

Your adult dog is comparable to a 30-year-old human.

Example 3:
A 7-year-old large dog: Human Age=24+(7−2)×7=59 years\text{Human Age} = 24 + (7-2) \times 7 = 59 \text{ years} Human Age=24+(7−2)×7=59 years

Your senior dog has reached an age equivalent to a 59-year-old human.
