Mother dogs may occasionally sit on their puppies as an instinctual behavior to protect and keep them warm. This action helps shield newborn puppies from predators and cold weather in the wild. However, in some cases, inexperienced or stressed mother dogs might accidentally sit on their puppies, putting them at risk of injury or suffocation. Therefore, monitoring the mother and her puppies during the early days is essential, intervening if necessary to ensure the puppies' safety and well-being.
