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.
Puppies develop from a fertilized egg to a viable fetus over a very short period of time-about nine weeks (58 â 63 days on average).This period is called âgestation.â Gestation ends when parturition (birth) occurs.Anyone breeding a litter should become familiar with the stages of fetal development so that they can take all steps necessary to attend to the needs of their pregnant dog and her future offspring.ource: PetWave, Updated on July 16, 2015.
