Some dogs will simply be crate phobic, and it takes a bit of work to try and reverse that mentality with them.
Kananga is crate phobic but he has improved over the years. Initially though, he was allowed full roam because crating was not an option. He was not destructive while outside of the crate so it worked out very well. Over time he has gotten more comfortable with his crate when shutting the door. I'll do this time to time when I'm cleaning to help isolate him, and he will be OK for a short period of time. I would never leave him in there and leave my home though, I know he still has that phobia and will injure himself while I'm gone.
You will either have to work through the phobia with proper conditioning, or accept the fact they are not willing to be crated and find a way to leave them out while you are gone. I don't have much experience trying to reverse the phobia as with Kananga it was very strong and he was fine to just be out all day, but I know others on here have had success with working through it when crating is a must and free roam is not an option.
