I think that if she is remodeling her home to the point she couldn't get to the registration papers to give you, she shouldn't have been having a litter(or litters for all we know) of puppies...I'm sure 2+ months ago, she knew her house was going to be going thru construction/remodeling. i can't imagine that is a good environment healthwise for newborn puppies to be in anyway...
Hope Carlie gets better and is able to find a home eventually...are you going to check back in on Carlie periodically?
Sorry you had to go thru that. I'm sure we can all relate to the excitement prior to receiving a new baby!
