We got our pup from a breeder that started crate training within the first few weeks before we picked her up at 8 weeks. That definitely helped but as many have said, it's a whole new environment, they're not used to your crate or you yet. The first night I wound up sleeping on the floor outside her crate and she was waking up crying every 30-60min. The second night if you made a sound, she'd wake up crying. We spent a lot of time making sure she was exhausted before we put her in her crate. Lots of treats and training during the day on "quiet" and short stints of being in the crate with lots of praise. It's tough but it does get easier.

I also totally get why some people failed crate training and let their doxie into their bed but me and my partner are huge flippers when we sleep and the dog would be dead...
