About
Built by a pet parent —
not a pet brand.
An independent project making free, honest pet calculators — grounded in veterinary research, not ad copy.
Our mission
Caring for a pet often means digging through outdated websites, conflicting advice, and paywalled tools just to answer a simple question — like how old your dog really is, or how much food they actually need.
bowwowpaw exists to change that. We build free, accurate, easy-to-use calculators grounded in veterinary research, so you can get a trustworthy answer in seconds — no sign-up, no tracking wall, no nonsense.
How we build
Four principles behind every calculator
Peer-reviewed science first
Formulas come from published veterinary research — like the 2020 epigenetic clock for dog age — not internet lore.
Breed and size aware
A Chihuahua and a Great Dane don't age the same. Our tools account for the differences that actually matter.
Transparent methodology
Every calculator shows the formula it uses and the sources it draws from. No black boxes.
Privacy-respecting
Calculations run in your browser. We don't store your pet's info, and you'll never need an account.
Who's behind bowwowpaw
An independent project — not a pet brand.
bowwowpaw is built by a designer who loves dogs, cats, and well-crafted tools. It's not backed by a pet food brand or a vet clinic — just a pet parent who wanted better answers than the ones already out there.
