Why this page exists
People usually want one of two things: a quick breed comparison or a deeper life-stage answer. The chart helps with the first question. The calculator handles the second.
It turns breed-level lifespan data into something you can sort, scan, and compare instead of reading one breed at a time.
The chart is good for browsing breed data, but the calculator adds age, health, and remaining-years context.
Large and giant breeds usually age faster after growth is complete, so their care timeline changes earlier.
