Thank you for all of the advice.
Our other GSD, Arrow, loves her wire crate, that we ordered from Amazon. Its "bars" are about double the thickness of this one, which we picked up at the local farm store. The one we have for General is definitely cheaper, and I can bend the bars by hand myself. Definitely not a good fit for a dog with a lot of strength and determination.
To answer the question of how long we have had him...today is day 12.
To answer the suggestion of tiring him out...it doesn't work. He has such severe anxiety that he can be in a dead sleep and if we get up to go to another room, he jumps up to follow us.
I've called my vet and have an appointment with him this afternoon to discuss options.
Typically, until August, it won't be a big deal because my wife is a teacher and is home on summer vacation. But there are a couple of times where he has to be in his crate...like when we go to church on Sunday, or if she has to run an errand. We are hoping to have him comfortable with a crate, or able to be left out by the time she has to go back to school
