Navigating Canine Gestation
A week-by-week breakdown of what to expect and how to prepare for the arrival of puppies.
The 63-Day Journey
Canine pregnancy usually lasts between 58 to 68 days, with 63 days being the average. While nature does most of the work, understanding the milestones can help you provide the best prenatal care for your dam.
Key Development Phases
- Days 1-21: Fertilization and implantation. The dam may experience minor morning sickness.
- Days 22-42: Puppies begin to take shape. Heartbeats can often be detected via ultrasound around day 25.
- Days 43-63: Rapid growth. Fetal skeletons become visible on X-rays after day 45.
Care Tips for the Dam:
- Nutrition: After week 4, gradually switch to a high-quality puppy food which is more nutrient-dense.
- Whelping Box: Introduce the whelping box at least two weeks before the due date so she feels safe and comfortable in it.
- Temperature Tracking: In the final week, check her rectal temperature twice daily. A drop below $99^\circ\text{F}$ usually indicates labor will begin within 24 hours.
