How long do dog labor last after the first puppy is born? - in detail
Dog labor typically progresses in stages, with the duration varying depending on several factors such as the size of the litter, the breed of the dog, and individual physiology. After the birth of the first puppy, the labor process can continue for several hours or even days, although it is generally divided into specific phases.
The initial stage, known as the progestational phase, occurs before any physical signs of labor are evident. This phase is characterized by hormonal changes that prepare the body for delivery. Once active labor begins with the birth of the first puppy, the subsequent stages can be broken down as follows:
-
Delivery Interval: This is the time between the birth of one puppy and the next. For most dogs, this interval ranges from 10 minutes to 2 hours. Larger breeds or those carrying a larger number of puppies may have longer intervals, while smaller breeds with fewer puppies typically experience shorter intervals.
-
Resting Phase: After delivering several puppies, the mother dog may enter a resting phase where no new puppies are born for an extended period. This can last from 4 to 24 hours and is a normal part of the labor process. The rest allows the mother to regain energy and prepares her body for the delivery of any remaining puppies.
-
Active Labor: After the resting phase, active labor resumes with the birth of additional puppies. This stage can continue until all puppies have been delivered. The total duration of active labor varies significantly but generally ranges from 6 to 12 hours for the entire process.
-
Third Stage of Labor: Once all puppies are born, the mother dog will begin expelling the placenta. This stage can take several hours and is crucial for the health of both the mother and the puppies. Each placenta should be expelled within 12 to 24 hours after the birth of its corresponding puppy.
It is essential to monitor the labor process closely, especially if it appears prolonged or if there are any signs of distress in the mother dog. If more than 4 hours pass without the delivery of a new puppy, or if the mother shows signs of fatigue or discomfort, veterinary intervention may be necessary to ensure the health and safety of both the mother and her puppies.
