Not veterinary advice
The human age equivalents, life stages, and lifespan figures shown on this site are estimates only and are not veterinary advice. They are not intended to diagnose, treat, or predict the health of any animal. Always consult a qualified veterinarian for decisions about your pet's health, nutrition, and care.
Accuracy of estimates
Animals do not age at a fixed rate. Our calculators use general models based on published reference data, average lifespans, and, for dogs, size group. Real aging varies with genetics, environment, diet, lifestyle, and individual health. Two animals of the same species and age can differ. Treat every result as a helpful approximation rather than an exact measurement. You can read how we build our models on the Sources & Methodology page.
