It's more of a rule of thumb than a fact really because in the first year of their life, dogs age more than 7 human years. I think they hit their teens by the end of year 1 and then their aging slows down a bit.
This is my understanding of it...
Year 1 - The dog ages to early teens.
Year 2-??? Dog ages approx 6.5 dog years to every human year.
So when you factor in the first year with the rest of their life, it averages out to probably about 7 dog years per human year, but like I said, it's more of a rule of thumb.
