Here's what to keep in mind:
* Individual Variation: Just like human births, each puppy's arrival is unique. Some might come quickly, while others might take a bit longer.
* Breeds: Some dog breeds are known to have larger litters and faster deliveries, while others might have fewer puppies and longer intervals between them.
* Overall Health: The mother dog's health and the size of the puppies can also influence the spacing between births.
If you're interested in learning more about the specifics of a particular dog's pregnancy or birth, consult a veterinarian. They're the best resource for providing accurate and personalized information.
