Betty's adorable twitching makes us feel good, and it’s fun to imagine her milk-filled dreams. But that’s not what makes her twitch and pop as she rests. This twitching actually has a functional purpose - "activated sleep" helps build muscle and form the connections that will allow the puppies to develop motor coordination.
This is why twitching is a key indicator that the puppy is healthy and developing normally. Breeders have recognized this for centuries, but modern research has showed us why. When the twitching stops, the puppy's not developing in some important ways, and is in critical danger.
