Not veterinary advice. Lifespan figures are broad statistical averages. Breed, care, diet, weight and genetics all shift the real number, so treat the result as a rough guide only.
Select dog or cat, pick the dog's size tier if relevant, and enter the current age in years. Press Calculate to see the typical lifespan range for that group and, from the current age, an estimate of how many years may remain. The size tier does not change the result for cats.
Not veterinary advice. This is a statistical estimate, not a prediction. Regular veterinary check-ups are the best way to support your pet's health and longevity.
