HI....I have a 6 mo old GSD male. He is not crated at night because he wakes us at night when he needs to go out. He was typically going twice a night but then for about 2-3 weeks started sleeping through the night. The past week or so he has been waking like clockwork at around midnight and 4:30 AM. He does pee a decent amount at 12 but at 4:30 not so much and I know he can hold it from 12-6. It's like he just wants everyone else to be awake like him..lol. We are exhausted. Last night I took him out again at 4:30..he did a small pee and came right in...2-3 min later he was jumping on my husband so I took him out again thinking he needed to poo. When I took him he just smelt where he had just peed, looked at me like I was crazy and came back in. He was restless until it was time to get up at 6. I don't think he's sick because he's not showing any signs...I think he just wants to be awake and wants us to be to. Any suggestions to get him to sleep the night again?
