Understanding Dog Pregnancy
Dog Gestation Period
The average dog pregnancy lasts 63 days from conception, but can range from 58 to 68 days. This is approximately 9 weeks or just over 2 months. The variation depends on factors like breed size, individual dog, and litter size.
Labor Signs to Watch For
- •Temperature drop of 1.8°F (12-24 hours before)
- •Restlessness and nesting behavior
- •Loss of appetite and increased thirst
- •Rapid breathing and panting
Breed Size Differences
Small Breeds
1-4 puppies, may deliver earlier, higher risk of complications
Medium Breeds
4-6 puppies, standard gestation period
Large/Giant Breeds
6-12 puppies, may carry longer, need extra nutrition
Important: Labor can last 12-60 hours. Always have veterinary support available during whelping.
