Owners use PetNatal while their dog is pregnant, so accuracy matters. These are the rules we follow for every page and tool.
Sources we use
We rely on veterinary references and university teaching hospitals first: the Merck Veterinary Manual, Cornell, UC Davis, Purdue, the AKC Canine Health Foundation and peer reviewed studies. We use breed clubs and the American Kennel Club for breed facts. Every figure on a page carries its source, and each page lists its sources at the bottom.
How we write and review
- We write for owners, in plain US English, and explain any medical term we use.
- We use AI tools to help draft and organize content. Every claim is then checked by our editors against the sources listed on the page before it is published.
- Calculator rules are tested against worked examples before each release.
- Each page shows the date of its last review. We review every page at least twice a year.
Corrections
If you spot an error, email [email protected]. We check every report, fix confirmed errors within a few days, and update the review date on the page.
Independence and advertising
PetNatal may show ads to keep the tools free. Advertisers have no say in what we write. We do not accept payment for recommendations, and we do not sell products under the PetNatal name.
Medical review
If a licensed veterinarian reviews a page, we will name them and the review date on that page. We never invent experts or credentials.
