Just my own experience here, as I got 9 week old Marvin a week ago today and he did NOT like the crate. By way of background - he was from a working farm, and he, his pups and his Mum slept in a very cozy barn (I saw it, don't worry!)
As per advice, I tried putting him in his crate, "start as we meant to go on" on night one, and he HATED it. He cried and cried, and whilst he eventually settled, he'd wake up almost on the hour crying and howling to the point he woke the neighbours up. I felt so terrible, but read everywhere to stay strong and let him cry it out, which I did.
Night one over, and hes ok the next day but won't go ANYWHERE near his crate. Not even with his food or water in it. Clearly he hated it. I managed to get him in and out briefly a few times when bribed with treats but its clear that he had no intention of staying in it. When I shut the door, just momentarily, he was biting at the wire to the point he got his teeth stuck and I had to "unstick" him.
Night two rolls round and I brace myself for another rough night. As predicted, exactly the same again. However, at about 4am (despite me taking him out not an hour earlier) he poos in his crate, and I have to clean him, his bed, the crate, (all the while in tears because of how guilty I felt!) before trying to settle him again.
Day 3 I tried to do more training to get him used to coming in and out of the crate, with the same result as before. I put lots of treats in, and shut the door, and stayed in the kitchen (but out of sight of Marvin). And he was so distressed, crying,howling, biting the wires, to the point that once again his teeth got stuck - and I mean REALLY stuck, he was clearly in pain and I had to unpick him. At that point, i decided we wouldn't be using the crate anymore, and I'd speak to my vet the next day. I wasn't risking broken teeth, broken jaws and a psychologically damaged dog!
Luckily it was the day of his first jabs the following day so I got to ask my vet the best way to do it. And she said that crates aren't for all dogs, and sometimes slowly slowly is the way forward, over a couple of weeks. Start by feeding him in there, but not fussing - put the food down and leave the room. Leave the door open at all times, so he can come and go as he pleases, and if theres a spare bed, pop it outside BY the crate and eventually move it inside. Lots of fuss and treats when he does go in, and slowly (with no fuss) try closing the door for a minute or two every now and then, and build it up.
Its been a week now, and today i've been able to shut the crate door for a few minutes with no fuss - and it felt absolutely fabulous to see him ok (ish) inside of it. In addition, since i've had the door open at night, he's slept like an angel, with no messes, no crying, no fuss.
I guess in summary - crates aren't for all dogs. But in time, they can be. You know your dog, so as long as you're consistent, just do your best and eventually they'll work out its actually a nice cozy place to be!
