Free Dog Age Calculator Widget
Add a working dog years calculator to your own site in one line of code — free, no sign-up, no ads of ours inside it. All we ask is that you keep the small "Powered by Dog Years" link.
Embed code
Copy this into your page's HTML wherever you want the calculator to appear:
Two versions
Compact — breed (or size) and age in, human-years result out. Fast-loading, minimal, good for sidebars.
Full — adds breed/size and birth-date/age toggles, an optional dog's name, and the classic ×7 rule as a comparison. Better as a standalone feature on a dedicated page or blog post.
A note on accuracy
The widget uses the same Royal Kennel Club size-adjusted ageing data as the main calculator — it isn't a simplified or less accurate version, just a smaller interface. It covers all 225+ Royal Kennel Club-recognised breeds.
