Thank you for submitting your question regarding Dojo. The gestation period of a dog is around 63 days. Unfortunately, there is no way to tell simply by looking at a dog how far along in pregnancy she may be. I recommend that she sees a veterinarian for x-rays of her belly. The fetal skeletons are visible after 45-50 days of gestation. The x-rays will also tell you how many puppies she is expecting. This is helpful information when she is in labor. I hope this information helps!

    If you know the date of the first mating then you will be able to calculate an expected due date. The website below has a calculator that will generate that information for you http://petsci.co.uk/dog-canine-pregnancy-calculator-calendar/ Typically bitches will give birth around 63 days after conception - it it can range between 56 and 70 days. The website below will give you information regarding what to expect at each stage of the pregnancy. http://www.royalcanin.co.uk/knowledge-centre/dogs-pregnancy-week-week/ Ultimately an ultrasound scan would be the most accurate way of estimating what stage of pregnancy your dog may be at currently but you would need to make an appointment with your veterinarian in order to do so. Best of luck!
