About PawNerdy

Free, practical tools and guides for dog and cat owners — no fluff, no gatekeeping behind sign-ups.

What we do

PawNerdy builds simple calculators and clear, direct answers to the questions dog and cat owners actually search for — from "how old is my dog in human years" to "why does my cat knead." Every tool on this site is free to use, with no account required.

Who writes this

Articles and tools are written and maintained by the PawNerdy Team. We're not veterinarians — we research each topic carefully using established veterinary sources and formulas, and we say so clearly when something is general guidance rather than a substitute for professional advice.

How we approach accuracy

Our calculators are built on commonly cited veterinary formulas and breed data (like the RER formula for calorie needs and standard growth-curve percentages for puppy weight estimates). Our articles are written to reflect general veterinary and behavioral consensus, and we're upfront when something is theory rather than settled fact. That said, this site is for general information only and isn't a substitute for advice from your own veterinarian, who knows your specific pet.

How this site is funded

PawNerdy is supported by advertising. Ads help keep every tool and article on this site free to use. We don't require sign-ups, subscriptions, or payment to access any of our content or tools.
