The duration of a dog's labor can vary significantly depending on several factors such as the size and breed of the dog, as well as the number of puppies. On average, the active stage of labor in dogs typically lasts between 6 to 12 hours, with some variations possible based on individual circumstances.
How long does a dog's labor last? - in detail
The duration of a dog's labor can vary significantly depending on several factors, including the size and breed of the dog, the number of puppies, and whether it is her first litter or not. On average, the entire process from the beginning of labor to the delivery of the last puppy typically lasts between 6 to 12 hours. However, it's important to note that each stage of labor has its own distinct characteristics and timeframes.
The initial phase, known as the pre-labor or prodromal stage, can last anywhere from a few hours to several days. During this period, the dog may exhibit signs such as restlessness, nesting behavior, and decreased appetite. The body temperature of the bitch may also drop slightly, usually by 1 to 2 degrees Fahrenheit (0.5 to 1 degree Celsius).
The active stage of labor is when the contractions become more intense and frequent, typically occurring every 10 to 30 minutes. This phase can last from 6 to 12 hours but may be longer or shorter depending on individual factors. The uterus contracts, pushing the puppies toward the birth canal, and the bitch will start to push and strain as if she is trying to defecate.
The delivery of each puppy usually takes about 10 to 30 minutes from the time the water sac (allantois) ruptures until the puppy is completely born. This includes the time it takes for the bitch to push the puppy out and for the placenta to be expelled. If the bitch is having a large litter, the delivery of all puppies can take several hours.
After the delivery of each puppy, the bitch should rest and recover before proceeding with the next birth. This resting period allows her body to regain energy and prepare for the subsequent delivery. It's crucial not to disturb or stress the mother during this time, as it can affect the overall labor process and the health of both the mother and the puppies.
If a bitch has been in active labor for more than 24 hours without delivering a puppy, or if there are signs of distress such as excessive panting, lethargy, or discharge that is not clear and odorless, immediate veterinary attention should be sought to ensure the health and safety of both the mother and her unborn puppies.
