Thanks for using Petco Pet Education Center, formerly Petcoach! It is a possibility but dogs can also have fake pregnancies- all the signs of a pregnancy but with no fetuses. I recommend taking her to a vet for an exam. They can take an X-ray 45 days after mating or look sooner with an ultrasound. Good luck and kisses to Luna!

    There is no way to tell at home unless she starts having puppies! Blood testing, x-rays, and ultrasound are tools a vet can use to diagnose pregnancy. Each is appropriate at a different stage of pregnancy. I would discuss this with your vet.

    Hello and thank you for your question on Petco Pet Education Center, formerly Petcoach! Yes! There is a way to know for sure and that is through an abdominal ultrasound at your local veterinarian. They will also be able to tell approximately how many puppies she is expected to have. I hope this has helped and best wishes to you and Kalpy!

    Hello, thank you for your question about Diva. Both a false pregnancy or a small litter are possible. I would be suspicious that it is more likely a false pregnancy based on what you are describing. However, the only way to know for sure would be to x-ray/ultrasound Diva’s abdomen to look for the presence of puppies. Hope this helps!
