Seems like I heard they get cold very easily! If you have experience with crested then I'm sure you know this, but you may want to keep a tshirt or onesie on her till she gets a little older. Hope she does okay. Makes sense to me for her to sleep a lot since she's so young. Good Luck to you. I hope she does well.
Gosh, I wish so many irresponsible people wouldn't breed dogs!! So frustrating.
