How Long Are Dogs Pregnant?

In these short articles, let’s call them Vet-Express, we will address topics that do not need much explanation.

Hence, in this case, the question is simply: Dr. Franck, how long is my dog’s gestation/pregnancy period?

The answer is probably a bit variable, although generally we talk about a duration of 58 to 65 days1 , although intervals of 57 to 68 days can be considered normal2. There are many factors that influence this length of time and it is obviously not possible to predict which bitch will take longer or shorter to whelp.

If there are any other quick questions you would like answered, please contact me!
