How old is your dog in human years?

We all know the saying "one dog year is seven human years", but it's not quite right. A dog's aging process is much more complex. Scientists now use biological markers to map their age to ours, revealing a truer picture of their life stage.

We use a research-backed formula to give you a precise age. Then, our AI steps in to provide personalized health and lifestyle insights for your furry friend.

The Science Behind the Numbers

It's not magic, it's modern biology. Here's a breakdown of how we calculate your dog's true age.

The Formula

The calculation is based on a logarithmic formula from UC Davis researchers:

16 * ln(Dog Age) + 31

Here, "ln" is the natural logarithm, which models the rapid aging in a dog's early life.

Why It Works

This formula is based on epigenetics—specifically, DNA methylation. These are molecular changes that act like a biological clock.

By comparing these "clocks" in dogs and humans, scientists created a curve that accurately maps their aging process to ours.

In Simple Terms

Dogs mature incredibly fast at first, then their aging slows down. Think of it like this: a one-year-old puppy is already like a 30-year-old human in terms of biological maturity!

This method gives us a much better understanding of their developmental stage.
