A Puppy's Need for Sleep

Another very important thing for developing puppies is sleep. They should sleep many hours a day, at regular times. You should make them go to sleep early and, likewise, make them get up early. No sleepy breeder that habitually deprives his puppies of the sweet early morning air will ever have success in the breeding of dogs.

As for the rays of sun, you must go preparing the puppies for the strong light starting between the 10th and 14th day. You can do this by placing the puppies in a semi shady place and little by little every day bringing them closer to the light. In the wild, the mother does the same thing with her puppies. After that, the rays of sun are a basic element for the development of the puppies.
