How this service works
Human-equivalent age of a dog by the AVMA 15-9-5 rule and the 2020 epigenetic-clock formula 16 ln(age) + 31.
Output
Returns the dog's human-equivalent age calculated via the AVMA 15-9-5 rule (humanYearsAvma), the 2020 epigenetic-clock formula (humanYearsEpigenetic), the difference between the two estimates (differenceYears), a flag indicating whether the epigenetic formula is reliable for the given age (epigeneticReliable), a plain-English summary, source attribution, and a disclaimer about the estimates.
Example use cases
Senior dog wellness check
“My golden retriever is 11 years old. How old does that make her in human years — can you use both the AVMA method and the epigenetic formula so I can see the difference?”
New puppy milestone tracking
“My puppy just turned 1. What's his human-equivalent age right now using the AVMA rule and the scientific epigenetic calculation?”
Comparing two dogs' relative ages
“I have two dogs — one is 4 years old and the other is 9. Can you tell me the human-equivalent age for each using both the AVMA and epigenetic methods so I can compare how much older the second one really is?”

Endpoint
GEThttps://pet-calc.x402tookit.com/dog-age?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need a scientifically grounded dog-to-human age conversion that goes beyond the outdated 'multiply by 7' rule. It uniquely provides two distinct methods — the veterinary-standard AVMA 15-9-5 rule and the 2020 epigenetic-clock formula — along with a reliability flag and difference metric, making it ideal for any pet health, wellness, or educational application requiring rigorous age context.
Side effects
- Missing dogYears query parameter returns a validation error
- Non-numeric or negative dogYears value causes a bad request error
- Very young or very old ages (e.g. 0 or >30) may trigger epigeneticReliable=false
- Payment failure (insufficient USDC balance or x402 protocol error) results in 402 response
