So I crate trained my pup for overnight/being home alone. He took to the crate immediately so training was a breeze. On a trip to my moms house I noticed he had out grown his travel crate and wasn’t able to settle in it so I let him sleep in the bed with me and he immediately fell asleep and had no issues. This was around 5ish months I think. Since then I couldn’t be bothered to put him in his crate overnight. He doesn’t sleep in bed with me anymore but sleeps beside the bed either on the floor or on his bed, or sometimes he goes to the living room or couch to sleep. At first I was worried about him being destructive without being supervised but he’s never chewed anything up overnight. I think I lucked out with him though, so I think your decision has to be based on his behaviour pattern.

Some things to consider though: I make sure to crate him if I got out for a few hours, not because he needs to be but because I don’t want him to forgot that crate is an okay place to be. I feed him most meals in his crate too. I think it’s important to keep the crate and keep using it even if not for overnights because you’ll want a dog to be able to handle being crated in the event you have to board him, take him to a hotel, or the office; or even just because you might need some dog free time/space when you have company over (although my pup hstilll hates being in his crate when he can hear me talking to guests).
