Who is training who? Certainly you can't complain about her behavior! At 11 weeks old, it's the best she can do. How could kibble be on the kitchen floor if she is fed in her crate, quiet and focused? Food is not a toy.
I can not imagine what you thought would be any different if you left the crate open all night.....no, wait, bungeed the door open so she could be sure to take care of business any where she wanted... any time she wanted.
Please sign up for a puppy kindergarten class, I think you need it, and your puppy will be much happier if you know what you are doing.
I don't mean to sound harsh, but where does common sense begin??
