when do dogs start producing milk
Another way to determine pregnancy is to draw blood 22-27 days post breeding to measure the relaxin level in the bloodstream. The length of pregnancy in dogs is approximately 63 days. Milk production in the pregnant dog starts 1-7 days before parturition. Milk production can also be present in pseudopregnant dogs. During pregnancy a mucoid to pink tinged vulvar discharge can be present in normal dogs. Monitor for and report any bloody or yellow-green discharge as these can indicate serious disease.
