Why the Date Range is Crucial

The average gestation period for dogs is **63 days** from the day of conception. However, due to several factors, including the timing of ovulation and breeding practices, the actual delivery can occur anywhere between **58 and 68 days**.

• **58 Days:** Puppies born before this date are often premature and rarely survive.
• **63 Days:** The median, or average, whelping date.
• **68 Days:** Delivery after this date may indicate a complication, such as uterine inertia or puppies being oversized.

Monitoring your dog closely around the estimated earliest date (Day 58) is essential. Consult your veterinarian immediately if gestation extends past Day 68.
