My dog is 40 days pregnant. When should I expect her puppies?

Updated On September 23rd, 2025

Pet's info: Dog | Mixed Breed Medium (23 - 60lb) | Female | unspayed | 50 lbs

About how long does it take for a knee high (medium sized) dog to have her puppies? It’s been 40 days and she looks like she’s about to pop, just wondering when would be best to expect the babies?

Hi there and thanks for posting on Petco Pet Education Center, formerly Petcoach! Dog have a gestation period (pregnancy) of around 60 days. If Blue is at or around day 40, then she's got just a little more time to go! I hope this helps and best of luck!
