The calculators, charts and articles on PetNatal give general information and estimates only. They are not veterinary advice, diagnosis or treatment, and they do not replace an exam by a licensed veterinarian.
Every dog and cat is different. Due dates are estimates, and normal ranges come from published veterinary references that may not fit your pet. Always follow your vet’s advice, and contact your vet or an emergency clinic right away if you think something is wrong.
We work to keep our content accurate and up to date, but we make no guarantee that it is complete or error free. PetNatal is not responsible for decisions made based on the information on this site.
