API, OpenAPI and WebMCP documentation

Explanation

Medium-breed dog estimate: first 2 years age faster, then ~4.5 human years per dog year. Model: two-stage-affine-v1. The coefficients are this site's educational model, not a validated measure of biological age. Breed, size, health and life stage affect interpretation. It is not the AVMA age chart: AVMA lists approximately 15 and 24 human years at ages 1 and 2; its dog chart refers to medium dogs weighing 21–50 lb. Comparison source: https://ebusiness.avma.org/files/productdownloads/PetsAgeFaster.pdf. The existing coefficients are retained pending a documented model review.

Questions & answers

Frequently Asked Questions

Is this medically exact?

No. It is an estimate for comparison, not a veterinary or medical assessment.

Can I use decimal values?

Yes. Fractional inputs are supported, but the result is still shown as an age estimate in days, weeks, months, or years rather than a biological or clinical measure.
