Terms of Use

Last updated: June 29, 2026.

By using Pet Calculator(the "Site") you agree to these terms. If you don't agree with them, please don't use the Site.

What we provide

Free, browser-based calculators for dog and cat owners: toxicity checks, age conversion, ideal weight, water and calorie needs, medication dosing, pregnancy due dates, and cost estimates. Everything runs in your browser, and we don't store the details you type about your pet.

Not veterinary advice

The calculators are informational estimates, not veterinary advice, diagnosis, or treatment. They use published formulas and reasonable assumptions, but every animal is different and results can be affected by breed, age, health and the accuracy of what you enter. Always confirm anything that matters — a medication dose, a toxicity decision, a diet change — with your own veterinarian, and in an emergency contact a vet or an animal poison control line immediately. Never delay professional care because of a number on this Site.

No warranty

The Site is provided "as is," with no warranties of any kind. We work to keep the formulas accurate, but we don't warrant that every result is error-free or current. Use results at your own discretion and never make an irreversible decision on an estimate alone.

Acceptable use

Use the Site for personal, lawful purposes. Don't try to disrupt it, scrape it at scale, or present its output as professional veterinary guidance.

Limitation of liability

To the fullest extent permitted by law, Pet Calculator is not liable for any loss, injury or damage arising from your use of, or reliance on, the Site or its results.

Changes

We may update these terms as the Site evolves; the "last updated" date above always reflects the current version.
