Behind the Formula
This calculator uses the American Veterinary Medical Association (AVMA) guidelines. It takes into account that:
- Dogs age faster in their first two years
- Smaller dogs live longer
- Larger dogs age more rapidly after 5–6 years
FAQ: Dog Age Calculator

Because smaller dogs typically live longer and mature more slowly, while larger dogs grow fast and have shorter lifespans.
Q2: What’s the dog age formula used here?
It depends on the dog’s size:
- Small dogs: 12.5 years per human year for the first 2 years, then 4.5 after
- Medium dogs: 10.5 years first 2 years, then 5 years
- Large dogs: 9 years, first 2 years, then 7
Q3: Is this calculator accurate?
It gives a veterinarian-informed estimate, perfect for everyday planning and awareness. For medical decisions, always consult a vet.
Q4: Can I use this for puppies?
