Free Dog Calculators for Your Website

How to add one

Pick a calculator below and press Copy code.
Paste it where the calculator should appear: a Custom HTML block in WordPress, a Code block in Squarespace, or Embed HTML in Wix.
Keep the credit line under the frame. It is how your visitors find the formula and sources.

Every calculator runs in your visitor’s browser: nothing they type is sent anywhere. The frame loads only when it scrolls into view, and when a formula is corrected here, the copy on your site updates by itself.

Questions

Is it really free?

Yes. The only ask is that the credit line stays under the calculator.

Do you track my visitors?

The calculator page counts views without cookies, the same way as the rest of this site, and nothing a visitor enters into a calculator leaves their browser. See the privacy page.

Is this veterinary advice?

No. Each calculator applies a published veterinary formula or threshold, and says so. It is a starting point for a conversation with a vet, which is why the toxicity calculators show poison control numbers when a dose is dangerous.

Can I get a different calculator or color scheme?

Possibly. Get in touch and say which calculator and where it would go.
