I got my dog at 12 weeks. She cried and threw a fit when I put her in the crate. She was pretty persistent, but I was more persistent. I slept on the couch next to her crate and I'm sure my neighbors heard her, but they were great about it. Your going to have to do one thing at a time and then both will come together(crate/potty training) My puppy did the same thing with the pooping...she was dewormed and that same night she pooped out the longest worms I've ever seen. She never pooped in the cage after that. About the same time she started settling down in the crate...it was about 5 days of really no sleep, but it worked. I concentrated more on her getting use to the crate first. I don't know if you are letting the puppy out at night, but that is another thing that you should do. At 4 months my puppy was out of her crate at night, but it still took me another 2.5 months to completely train her. I was very frustrated, but she turned out to be a great dog and she is completely house trained.
