How to calculate the estimated date of delivery?
The duration of pregnancy for dog is 58 to 65 days. You are suggested to measure the rectal temperature every day when it is resting. This measurement should be proceeded one week before estimated date of delivery. The rectal temperature is normally 38-39 degree, if there is 1 degree above, it might give a birth within 1 to 3 days. If the pregnancy is not in plan and you find it by surprise, it is ok to measure the degree from now on.
