Canine Parturition/Whelping. The best way to know when the dog is going to whelp is to have ovulation timing and specific hormone and breeding dates. Often we do not have that information, and since the average gestation is 63 days but can be between 57 to 72 days from a single breeding, it can be difficult to tell when the dog is going to whelp. Canine parturition/whelping occurs in 3 stages. The first stage is when the uterus begins to contract and cause the cervix to dilate. Stage one can last 6 to 12 hours in the dog. Signs that you may see in the female are restlessness, panting, pacing, or nesting type behavior.
During the first stage the cervix dilates and contractions begin. Your female will be uncomfortable, restless, pace and pant. This lasts 6-18 hours. During the second part of labor, your female's contractions begin in ernest. Her water breaks and puppies are delivered usually after 10-30 minutes of pushing.All puppies are born during this stage. The third stage of labor is after all pups have been delivered and is when a dog still has small contractions to expell fluids and/or placentas from the uterus.er water breaks and puppies are delivered usually after 10-30 minutes of pushing.
