Who are we timing?

Start with the dog basics. Breed profile can suggest a size automatically, but you can still override it.

Step 1

Lifestyle and care

What shapes the years?

These inputs refine the wellness context. They do not diagnose health, but they make the estimate more useful.

Step 2

Often the biggest factor for older dogs. Choose the option that matches the current medical reality, not the most optimistic one.
