How would you like to start life with half a dozen whimpering brothers and sisters? That’s how most dogs come into the world—as part of a litter. The size of a litter varies, from an average of 4 to 8 puppies for small to medium dogs to 6 to 12 puppies for large dogs. Really big dogs can have more than 20 puppies!
A litter is a dog’s first family—and its first school. A litter usually stays together for 8 to 12 weeks. During that time, a puppy learns how to stand on its own four paws and act like a dog.
