Based on breed data, size, weight, and lifestyle factors. Not a guarantee — just a statistical estimate.
This tool uses breed-specific lifespan data from veterinary studies, adjusted for lifestyle factors that research has shown to impact longevity:
Each breed has a statistical average lifespan based on veterinary mortality studies. This is the starting point.
Overweight dogs live 1.8 years less on average. Obese dogs live up to 2.5 years less. Lean dogs may live 6 months to 1 year longer than average.
Moderate exercise adds 0.5-1 year. Sedentary lifestyle subtracts 0.5-1 year. Active dogs (within reason) show the best outcomes.
