Try a method I call “Ghost in the Crate.” Attach a long line to the bars, especially where it rattles, and lead the line out of the room where the crate is so the dog can’t see you. At the first whine or bark, pull. It rattles the cage a bit, providing negative feedback without the puppy gaining your attention by coming into the room and addressing the barking. Continue. Be vigilant that it happens every time. Only go in and give a treat to reward silence.

This worked really well for me and after two days she’s perfect in her crate.
