How long do the first labor pains last in dogs? - in detail
The duration of the first stage of labor in dogs, often referred to as the latent phase or prodromal period, can vary significantly depending on several factors such as the dog's breed, size, and individual physiology. This initial phase is characterized by subtle signs that labor is approaching rather than active contractions. During this time, the dog may exhibit behavioral changes such as nesting, restlessness, decreased appetite, or a drop in body temperature. These early indicators can last anywhere from 12 to 36 hours before the onset of true labor contractions.
As the dog's body prepares for delivery, hormonal changes trigger the release of oxytocin, which stimulates uterine contractions. The first stage of labor is considered complete once active labor begins, marked by strong and regular contractions that lead to the dilation of the cervix and eventual expulsion of puppies. It is crucial for owners to be aware of these early signs and monitor their dog closely during this period, ensuring a safe and successful delivery.
