Dogs like a den. Crates serve as that.
If they don’t haveba designated den they’ll usually find one of their own.
My last dog made the master bath her den.
The dog I had as a kid made the space under a corner group table his.
The dogs we have now have crates.
I took the doors off because they were making them take up even more space.
The dogs sleep in them all the time.
