How long is a dog pregnant?

The average gestation period for dogs is 63 days from the date of ovulation, but it can range from 58 to 68 days.

Can I tell how many puppies she will have?

Not with a calculator. An ultrasound (around day 25-30) or X-ray (around day 55) is the best way to determine litter size.

What are the signs of labor?

Drop in body temperature (below 100°F), restlessness, nesting behavior, panting, and loss of appetite are common signs labor is approaching.

Preparing for Whelping

A dog's pregnancy flies by relatively quickly. Here is what to focus on:

Nutrition: Switch to a high-quality puppy food during the last few weeks of pregnancy to support lactation.
Nesting Box: Introduce the whelping box about a week before the due date so she gets comfortable with it.
Temperature Monitoring: Start taking her temperature twice a day starting Day 58. A drop below 100°F usually means labor will start within 24 hours.
