Dog pregnancy is an exciting yet delicate time that requires careful monitoring and proper care. Understanding the pregnant dog timeline helps pet owners prepare for the different stages of fetal development, nutritional needs, and behavioral changes.
In this guide, we’ll break down the entire dog pregnancy timeline, from conception to birth, covering symptoms, care tips, and what to expect at each stage.
1. How Long Are Dogs Pregnant?
The average dog pregnancy lasts approximately 63 days (9 weeks), though this can vary slightly between 58-68 days depending on breed size and individual factors.
Pregnancy Duration by Dog Size:
-
Small Breeds: 58-63 days
