Dog Pregnancy Weight Gain: What to Expect
A pregnant dog typically gains 15-25% of her pre-pregnancy body weight by the time of whelping, depending on litter size. Weight gain is minimal in the first few weeks, then accelerates from week 5 onwards as the puppies grow rapidly. Our dog pregnancy weight gain calculator tells you whether your dog’s weight gain is on track.
Expected Weight Gain Timeline
| Week | Small Litter | Medium Litter | Large Litter |
|---|---|---|---|
| Week 1-4 | Minimal | 1-3% | 2-4% |
| Week 5-6 | 3-7% | 5-10% | 8-13% |
| Week 7-9 | 10-20% | 15-25% | 20-35% |
FAQs
How much should I feed my pregnant dog?
Weeks 1-5: feed normal adult amounts (puppies are tiny and nutritional demand is low). From week 5, increase food by about 25% per week so that by whelping she is eating 50-100% more than normal. Use a high-quality puppy formula food from week 5 onwards for higher caloric density and nutrients.
Should I give supplements during dog pregnancy?
A high-quality puppy formula food should be nutritionally complete. Do NOT supplement calcium during pregnancy — excess calcium can cause eclampsia (milk fever) and interfere with the natural hormone signalling needed for whelping. Only supplement under direct veterinary guidance.
