Hi sir..Puppies at 7 to 8 weeks old need 18 to 20 hours of sleep in a 24 period for normal mental and physical development. During puppyhood their bodies develop at a fast pace. It takes a lot of energy for the bones, muscles and brain to develop.. Their sleep is strongly polyphasic they alternate short periods of feeding and activity with sleep throughout the day.
