Newfoundland age in human years
Even among dogs, newfoundlands run on fast-forward. The first year counts for 12 human years and the second adds 10, so a two-year-old is already 22. After that each year adds about 7.5, the fastest rate of any size class. A five-year-old is around 45, and senior status typically arrives near 6. Most live in the 7 to 10 range, and one reaching 10 is doing well.
