Not veterinary advice
The calculators, charts, tables, articles and other content on Animal Gestation Calculator (“the Site”) are general information for planning only. They are not veterinary advice, diagnosis or treatment, and they do not replace a qualified veterinarian. Every animal is different. Always consult a qualified veterinarian about the pregnancy, health, feeding, breeding and birth of your animal.
Emergencies
If you think an animal is in distress, is having difficulty giving birth, is bleeding heavily or is seriously unwell, contact a veterinarian or emergency animal service immediately. Do not wait for, or rely on, information from this Site.
Estimates only, no guarantee
- Dates, ranges and figures are estimates based on published averages and general sources. Actual gestation length varies with breed, individual animal, litter size, season, nutrition, health and the accuracy of the dates you enter.
- A calculated date is not a guarantee that birth will happen on that date. Healthy animals may give birth earlier or later than any estimate.
- We make no promise that the Site is accurate, complete, current or suitable for any particular purpose.
