Why does the dog mother move the puppy to the nest?

The dog mother moves the puppy to the nest out of maternal instinct. If the dog mother feels that her safety is threatened, she will instinctively move the puppy to the nest. The mother dog will take the puppy in her mouth to the place it thinks is the safest. When the mother dog moves the puppy to the nest, don't stop it. It's better to pretend not to see it. Otherwise, the dog mother will repeatedly move the puppy around to avoid any unsafe factors.
