Welcoming a litter of puppies into the world is a heartwarming experience. Understanding their early development is crucial for ensuring they grow into healthy, well-adjusted dogs. Here are 12 fascinating facts about newborn puppies that every pet parent should know:
1. πΎ Rapid Development

4. π½ Dependence on Mother for Elimination
