This question is for the future. Kai, our puppy (9 weeks) has been good about going outside but I think it is because we take him out consistently every 2.5 hrs. We have a crate (always open) in pen and that's where he is at night. He chooses to sleep in his crate but will choose to sleep out also (within the pen). We keep alarms for every 2.5 hrs and take him outside. He pees or pees and poops and comes right back and sleeps. How do I know if he is ready to push that 2.5 hrs limit? We are upstairs and he is downstairs and we can't hear him well (mostly because we sleep soundly). Should I move him up or should I sleep next to him? Please suggest. Thank you!
