Yeah that’s part of crate training lol. He’ll get used to it, chances are he’s making a much bigger fuss because he knows he’ll get attention if he does. Try incentivizing him to get in with treats, and then reward him with treats once he calms down and he’ll get it soon enough. You just have to stay consistent and really be the boss with dogs. Dogs want to be your friend but they need to know that you are in charge. My dog had a ton of behavioral problems when he was young, and when we brought in a dog trainer, the trainer did more work with us than the dog lol. Once me and my parents understood that we were in charge, the dog’s behavior problems basically vanished lmfao. Dogs need to understand their place in the house to not go insane lol.
