A whelping dog is one that has recently given birth and is nursing her puppies. She may exhibit increased protectiveness, fatigue, and changes in appetite during this period.
What is a whelping dog like? - in detail
A whelping dog, also known as a bitch in heat or a dam, undergoes significant physiological and behavioral changes as she prepares for and experiences giving birth. The process of whelping is typically divided into three stages: dilation, delivery, and expulsion of the placenta.
During the initial stage of dilation, the bitch may exhibit signs of restlessness and discomfort as her body begins to prepare for labor. This phase can last anywhere from 6 to 24 hours, with the cervix dilating in response to hormonal changes. The dam's rectal temperature may drop below 100°F (37.8°C) as a precursor to labor, signaling that the body is conserving energy for the upcoming event.
The second stage of whelping, delivery, is characterized by strong contractions and the expulsion of puppies. The bitch will typically begin delivering her offspring within 24 hours after the onset of labor. During this phase, it is crucial to monitor the dam closely to ensure that each puppy is delivered safely and that the mother's health remains stable. It is not uncommon for a bitch to take short breaks between deliveries, which can last up to an hour or more.
The final stage of whelping involves the expulsion of the placenta. After giving birth, the dam will typically pass each puppy's placenta within 15 to 30 minutes. It is essential to ensure that all placentas are accounted for, as any retained placenta can lead to serious health complications for the mother.
Throughout the whelping process, it is normal for a bitch to exhibit various behavioral changes. She may become more protective of her environment and display increased aggression towards other pets or humans who approach her nesting area. Additionally, the dam will instinctively clean her newborn puppies, stimulating their breathing and circulation.
In summary, whelping is a complex and multifaceted process that requires careful observation and support from the owner. By understanding the intricacies of each stage, one can better ensure the health and well-being of both the dam and her newborn offspring.
