I agree, with the above. Since she's young, if you think she's a dog you can't handle rehome her while she is this young.
crating from 6:30 pm to 6:30 am, is a loooong time..Puppies can be like toddlers, they need ALOT of attention. Sure I'd crate her at nite, but I'd be wearing her butt out and mine don't usually settle for the night until about 9 or 10, when I go to bed.
I'm going to move this thread to the puppy section
