Pregnancy and lactation are the most nutritionally demanding states a dog can be in. A nursing mother at peak lactation (3–4 weeks postpartum) may require 2–3 times her normal caloric intake. Inadequate nutrition during pregnancy causes low birth weight puppies, poor immune development, and milk production problems. The current veterinary standard is to feed a high-quality puppy food (AAFCO 'all life stages' or 'growth and reproduction') throughout gestation and nursing.

What is the best dog food for pregnant dogs?
A high-quality puppy food is the veterinary recommendation for pregnant and nursing dogs — it provides the higher protein, fat, calcium, and DHA needed for fetal development and milk production. Purina Pro Plan Puppy is our top pick: AAFCO 'growth and reproduction' certified, backed by feeding trials, and highly palatable during the appetite fluctuations of late pregnancy.
How much more should a pregnant dog eat?
During early pregnancy (first 6 weeks of a 9-week gestation), feed normal maintenance amounts. In the last 3 weeks of pregnancy, gradually increase food by 25–50%. During peak nursing (weeks 3–4 postpartum), a dog can need 2–3 times her normal caloric intake. Free-feed high-energy puppy food during nursing — restricting intake during lactation causes rapid weight loss and poor milk quality.

Many vets recommend switching to puppy food at week 5–6 of pregnancy (gestation is 63 days / ~9 weeks). Some recommend switching at conception if planned. Transition gradually over 7 days. Continue feeding puppy food throughout nursing until puppies are weaned at 7–8 weeks. Then transition the mother back to adult food over another 7 days.
Do NOT supplement calcium during pregnancy unless your vet specifically prescribes it. Excess calcium supplementation during gestation suppresses the parathyroid gland, which increases the risk of eclampsia (life-threatening calcium crash) after whelping. The calcium in a quality puppy food is carefully balanced. Adding extra calcium disrupts this balance and creates dangerous risk during nursing.
