Puppy problems...?

Sounds like she needs to be crate training. You should teach her that her crate is a fun, safe place. She's chewing a lot because she's a puppy and she needs to chew. Give her some toys and bones. It looks like she might be bored as well, so give her plenty of exercise and do some training with her. You can train her to do some tricks and it can be fun for both of you!
