Take her temperature daily as her expected delivery date approaches. Normally a dog's temperature is between 101 and 102 degrees. When your pregnant dog's temperature drops below 100 degrees, that's an indication she'll have her puppies within 24 hours. Once labor begins, it can last up to 12 hours. If your dog's temperature drops significantly, she's ready to give birth soon.
When this occurs, expect labor to begin within 24 hours. Once active labor begins and the first puppy is delivered, you can expect a delivery every 45 to 60 minutes. If your dog is having a large litter, it is common for her to take breaks in between puppies. These breaks can last as long as two to four hours.
