PetNatal makes free pregnancy and due date tools for dog and cat owners in the United States. We built it for the moment you find out your dog may be expecting and want clear answers: when the puppies are due, what to check each week, and when to call the vet.
Who we are
PetNatal is run by a small editorial team. We write in plain language, check every figure against veterinary references, and keep the tools free to use. We do not sell supplements or breeding services, and nothing on this site is a paid recommendation.
How our content is made
- Veterinary sources first. Gestation ranges, test timing and warning signs come from references such as the Merck Veterinary Manual, Cornell University, UC Davis and the AKC Canine Health Foundation. We cite them on each page.
- Owners’ real questions. We read what owners and breeders ask in forums and vet Q&As, so the tools answer the questions people actually have, such as slip ties, temperature dips and overdue dates.
- Checked and updated. We review each page at least twice a year and whenever a source changes. The date at the top of each page shows the last review.
What PetNatal is not
Our tools give estimates. They are not a diagnosis and they are not veterinary advice. Every pregnancy is different, so please keep your vet in the loop, especially in the last week.
