There's a reason crates are illegal in some of the countries we think of as the most civilized and humane. I've seen dogs- particularly sensitive working dogs- become very disturbed by so called 'crate training'. I think if your very young dog is showing symptoms of distress you really should rethink.
I would argue there is nothing uncivilized about crates. nor do they have to be disturbing to dogs.
I would further argue that the issue isn't the crate, but how the dog was trained to use the create. Methods, pace, expectations for progress etc. Another issue is often the advice given for using it, sizing it to the use etc.
The fix is to use humane training, not ditching the crate.
If it appears someone is using a crate poorly, do not assume a bad person. They are more than likely just following the poor advice of an "expert" who isn't.
