🐶How to Calculate Your Dog’s Age

We’ve all heard that one dog year equals seven human years — but is that really true? Not exactly. Dogs age differently depending on their size, breed, and growth rate, so there’s no single rule that fits all.

Here’s a simple and practical way to estimate your dog’s age more accurately.

🐾 Why the “1 to 7” Rule Doesn’t Work

That old formula is just a myth. If it were true, a 15-year-old dog would be 105 in human years — and we all know many dogs reach that age in great shape!

Dogs grow and mature much faster during their first years, and that’s why the aging rate slows down after the first and second year of life.

📊 A Practical Way to Calculate Your Dog’s Age

You can use this simple guide to estimate your dog’s age depending on its size:

🐕 Small Dogs

·         First 2 years = about 25 human years

·         Each additional year = +4.5 human years

🐶 Medium Dogs

·         First 2 years = about 21 human years

·         Each additional year = +5.7 human years

🐩 Large Dogs

·         First 2 years = about 18–20 human years

·         Each additional year = +7–8 human years

🧮 Example

If you have a medium-sized dog that’s 5 years old, here’s how it works:

·         First 2 years = 21 years

·         Remaining 3 years × 5.7 = 17.1 years
➡️ Total: approximately 38 human years

❤️ Why It Matters

Knowing your dog’s age isn’t just about numbers — it’s about understanding their story.
Each stage of life deserves the right kind of care, comfort, and love.

Understanding their age helps you:

·         Adjust their diet and activity level to match their energy and health.

·         Schedule vet check-ups at the right time to keep them safe and happy.

·         Recognise behaviour changes that come with each new phase of life.

·         Choose accessories and comfort essentials that support their growth — from the first walk to their senior years.

Because when we understand how they age, we can love them even better. 🐾
