How did the dogs managed to sleep outdoors?

Dogs can sleep outdoors comfortably due to their natural instincts and adaptations. They have thick fur coats that provide insulation against cold weather, and they often seek out sheltered spots to protect themselves from wind and rain. Additionally, dogs tend to curl up or dig into the ground to create a cozy nest, which helps retain body heat. Their ability to relax in various environments also enables them to sleep soundly outdoors.
