The phrase "newborn puppies" refers to a litter of very young, newly born dogs that are only a few days or weeks old. These tiny creatures have just entered the world and are still in their early stages of development, relying on their mother for nourishment and protection. They may be small, fragile and vulnerable but they also possess an incredible capacity to grow, learn and adapt as they mature into healthy, happy puppies under proper care and attention from their owners or breeders.
