Dear all, May I know how many hours does your puppy sleep in a day? Do they sleep without waking up for long hours or they constantly woke up every 1-2 hour of sleep? The reason why I ask this question is that my puppy seems to sleep whole afternoon everyday and he is very active at night. Eventhough he fell asleep at night, he will be awake in the middle of the night and keep barking /whining until I have to attend him. Usually he will take a short nap around 11pm, then will wake up at 2am. Then he will sleep again at 3am and wake up at 5am. - How can I change his sleeping hours? - Do you face the same problem with your puppy? - Should I not allow him to sleep at in the afternnon and keep playing with him until he is exhausted, and hopefully he will have a long sleep at night without disturbing me and my neighbours?
