I really have no idea. She's still a puppy. Just some thoughts off the top of my head:
1) Maybe she's mad 'cause she doesn't get to sleep with you?
2) Perhaps she doesn't get enough exercise during the day and evening, so
that she is tired enough to sleep through the night?
3) Does she have enough toys to keep her entertained and the people
willing to spend the time playing with her?
4) Did her adult teeth come in OK? Were the baby teeth removed if they all
didn't come out?
As I said, I have no idea. Just throwing some ideas out there to consider.
