Awwwwwwww POOR YOU!

I do hope everything goes ok, I think an extra large box might be in order, As like you said you do need time to get her used to things before she starts to litter. With around a week to go i think you might be stuck...

I know some people add photos of their dogs so that breeders on here can help a little...I dont know if this would in your case..!

Sorry i have never had puppies....So im rubbish at this sort of thing :O lol
