@recovering Yeah, as someone from one of those countries, this is one of the things that seems super weird in this sub. I know the AKC says it's essential for house training etc. and many trainers recommend it (apparently?) in NA, but it's practically unheard of where I'm from.
Dogs learn not to go in the house, not to destroy stuff, and to settle down just fine with no crates in sight around here, which always seemed a lot more practical to me. Takes longer perhaps, but how are they supposed to learn to live in a household when they're not allowed to be a part of it?
Most dogs are house pets meant to live alongside people, not reptiles in a terrarium; why do people insist that it's somehow more natural for them to be in a cage for hours on end? I don't understand that at all.
I'm sure it has its applications and it surely isn't bad for a dog to learn that being confined isn't the end of the world, should they ever have to be crated at the vet, for transportation, or in emergencies, but literally nobody I know uses crates daily as recommended on this sub.
As an end note, it might be important to understand how dogs sleep, as well. They do have deep REM sleep, but just like other animals, this is just part of how they sleep. A big part of their rest is also light snoozing, from which they might wake easily at any time - that isn't bad, that's normal! When dogs are tired, they'll sleep and they'll choose an appropriate place for what they need; trust them. They're sentient beings, they'll figure it out.
