- [False Pregnancy in Dogs: Signs, Causes, and What to Do](https://dogduedatecalculator.com/blog/false-pregnancy-in-dogs/): A false pregnancy in dogs, also called a phantom pregnancy or pseudopregnancy, is when an unspayed female shows the signs and behaviour of pregnancy even though she is not actually pregnant.
- [Dog Pregnancy Test: Relaxin, Ultrasound, Palpation and X-Ray Explained](https://dogduedatecalculator.com/blog/dog-pregnancy-test/): A human pregnancy test does not work on a dog. Human tests detect hCG, human chorionic gonadotropin, a hormone dogs do not produce.
- [How Soon Can You Tell If a Dog Is Pregnant?](https://dogduedatecalculator.com/blog/how-soon-can-you-tell-if-a-dog-is-pregnant/): You can usually tell if a dog is pregnant from about day 21 after breeding, when a vet may be able to feel the puppies by abdominal palpation, but the most reliable confirmation comes later.

- [How to Tell If Your Dog Is Pregnant: Signs, Tests, and What to Do Next](https://dogduedatecalculator.com/blog/how-to-tell-if-your-dog-is-pregnant/): The short answer is that no sign you can see at home confirms pregnancy in a dog.
