I don't know that keeping a dog in a crate is all that unfair, especially after working from home pretty much since the pandemic started. Dogs are possibly lazier than cats. My older dog, who we never crate, sits in the same spot all day and does not move. Occasionally I check on him just to make sure he isn't dead. My other dog is almost 2 years old, so we were crating him when we went to work before the pandemic started. Even though he doesn't have to, he spends basically his whole day in his crate with the door open. The young pup is maturing and pretty well behaved now, so I'm not sure we will crate him when I go back to the office, but I wouldn't feel the least bit bad about it if we did since he spends the whole day in there anyways.
I've heard or read or something that if the crate is an enjoyable place for them, it's not a punishment and they don't treat it as such.
Like cozy blankets, maybe snack, etc. something they associate with and there's no harm to having them go in.
