Not really the babies come out easy its like a baby coming out of a slide they just slide down..and there out...if a baby puppy does not cry then you will have to help it out ..trust me my dog had 7 labors I'm very experienced.
Your dog can be pregnant for 63-66 days before giving birth to puppies. You should get her abdominal ultrasound after 50 days of gestation to know the possible date of delivery, birth defects and possible litter size. When she will approach to labor, she will show some sign before start of labor. These signs can start 8-48 hours before actual start of labor pain. These signs are
- Reduction in rectal temperature below 100 F
- Agitation
- Loss of appetite
- Nesting behavior
- Frequent visits to nest
- Restlessness and pacing
