Here's why:
* Milk production can start early: Some dogs might start producing milk a few weeks before they are due to give birth. This is called colostrum and is a special type of milk rich in antibodies that are crucial for the puppies' immune system.
* Individual variation: Gestation periods in dogs can vary slightly. The average is around 63 days, but it can range from 58 to 67 days.
* Other signs: To get a better idea of when your dog might give birth, look for other signs:
* Swollen vulva: This is a more reliable indicator that labor is approaching.
* Nesting behavior: The dog might start looking for a quiet place to settle down and give birth.
* Restlessness: The dog might become more restless and anxious in the days leading up to labor.
If you suspect your dog is pregnant, it's important to contact your veterinarian. They can monitor her progress, confirm pregnancy, and advise you on what to expect.
Remember: It's best to rely on professional advice for accurate information about your dog's pregnancy.
