Cali is 7!

Cali turned 7 a few days ago!

Naturally, we celebrated at her favorite place in the world, conveniently located a short walk from home: Big Dipper ice cream. I know, it’s December. Cali does not feel the cold. Or have much sympathy for anyone who does.

We got our order (to go) and she collected and devoured her puppy cone.

The real treat was the cup of vanilla ice cream she got to eat at home. A few photos, above, show her delight.

Coincidentally, this week I heard about a new way researchers are calculating a dog’s human age equivalent. The common formula of a dog aging seven (human) years for each calendar year is too simplistic.

This new method looks at changes in our DNA over our lifetimes and compares dogs’ DNA changes to map a roughly equivalent human age onto the dog. There’s a calculator at the link above. The study used Labrador retrievers, but claims that the mapping is similar for all dogs. I am curious about whether they will repeat the research on smaller-breed dogs, because those dogs tend to have a longer lifespan so it seems like the mapping might turn out a little different.

In any case, Cali, a golden, is similar to a Lab in size and typical lifespan, so I checked out her age.

I was not happy with the results. Under the old mapping, she’d be roughly at the same life stage as a 49-year-old human; under the new mapping she’s 62!

The aging seems to slow way down after the first year, though. A 1-year-old Lab is roughly equivalent to a 31-year-old human, while a 13-year-old dog maps to only age 72.

Whether she’s 49 or 62 or 7, Cali is still a puppy at heart, silly and playful. And I hope she stays that way for many more years!

  1. Thanks for this post – it was really interesting trying out the calculator. My dog sure seems younger than 37, but I guess individual dogs age differently the same way individual people do. I know ‘old’ 70 year olds and ‘young’ 70 year olds. I wonder if they will tweak it for all breeds at some point. My pup is a 40 pound pitmix.
