How do dogs give birth and what are the key stages of the birthing process for dogs?

Dogs give birth through a process called whelping. The key stages of the birthing process for dogs include the onset of labor, the delivery of puppies, and the expulsion of the placenta. During labor, the dog may exhibit nesting behavior and panting. The delivery stage involves the actual birth of the puppies, which can take several hours. After each puppy is born, the mother will typically clean them and sever the umbilical cord. The final stage is the expulsion of the placenta, which usually occurs after each puppy is born. It is important to monitor the mother and puppies closely during the birthing process to ensure their health and safety.
