Pregnancy week by week

Around 63 days from ovulation to whelping — here is what happens and what the bitch needs along the way.

Weeks 1–4

Fertilized eggs implant around week three; some bitches show morning sickness or appetite dips. Keep normal exercise and normal food. An ultrasound from about day 25–30 can confirm the pregnancy.

Weeks 5–7

The belly rounds and appetite grows — switch gradually to energy-dense food (often puppy food) and feed smaller, more frequent meals. Gentle daily walks maintain muscle for the delivery ahead.

Weeks 8–9

Set up the whelping box in a quiet room and let her settle in. From about a week before the due date, take her temperature morning and evening — a drop of about one degree usually means whelping within 24 hours.

Test yourself: Pregnancy & whelping

How long is a dog's pregnancy on average?
  1. About 90 days
  2. About 63 days from ovulation
  3. About 40 days

Correct answer: About 63 days from ovulation

Around nine weeks — 63 days from ovulation — with a few days' normal variation.

What does a temperature drop of about one degree near the due date usually mean?
  1. Whelping within roughly 24 hours
  2. The bitch is ill
  3. Nothing — temperature varies randomly

Correct answer: Whelping within roughly 24 hours

The pre-whelping temperature drop is the classic signal that labor is about to start — measure morning and evening the last week.

Which situation during whelping means calling the vet immediately?
  1. A 90-minute pause between puppies while the bitch rests calmly
  2. The bitch eats the placentas
  3. Strong contractions for 30–60 minutes without a puppy arriving

Correct answer: Strong contractions for 30–60 minutes without a puppy arriving

Unproductive labor suggests an obstruction — that is an emergency. Calm pauses between puppies are normal.

How should the bitch's food change in late pregnancy?
  1. Gradually to energy-dense food in smaller, more frequent meals
  2. Strict diet to keep puppies small
  3. Double rations from day one of pregnancy

Correct answer: Gradually to energy-dense food in smaller, more frequent meals

Energy needs rise mainly in the final third — dense food in small meals fits the shrinking stomach space.
