What are the estimates based on?
The main calculation uses a simplified age model: 15 human years at age one, 24 at age two, then a size-dependent increment. Breed selection supplies a typical adult size and average lifespan, rather than an individual biological age.
The first two values follow common AVMA and AKC guidance. Pawometer uses fixed annual increments of 4, 5, 6 or 7 after age two and interpolates puppy ages between its stated anchors. These are modeling assumptions, not a clinical assessment. The model assigns life stages from age and average lifespan; it does not predict how long an individual dog will live.
The separate DNA comparison uses Wang et al. (2020), based on 104 Labrador retrievers. It measures a different aspect of aging and should not be treated as a universally validated replacement for the main estimate. Sterilization status does not adjust either result.
Has a veterinarian reviewed Pawometer?
We have not documented an independent veterinary review. Citations identify the background sources; they do not mean the authors or veterinary organizations have reviewed or endorsed Pawometer.
If an independent review is completed, this page will identify the reviewer, their credentials, the review date and the exact content covered. Until then, no reviewer credentials or approval date are presented.
For questions about sources or corrections, email silvanopara@gmail.com with the page address and the passage concerned.
How should I use the result?
Use the result as an approximate comparison and a starting point for learning about life stages. It is not a health score, a diagnosis, a treatment recommendation or an estimate of remaining lifespan.
Dogs of the same breed and age can have different health and care needs. Genetics, environment and individual history are not measured by this calculator. A veterinarian who knows your pet can assess those factors.
The printable certificate and comparisons with other animals are for enjoyment. They are not official medical records or evidence of veterinary certification.
