I know the rescue have said they can't find any medical reason as to why the dogs are so small, but surely the best place for them would be with owners that understand the breed and are prepared for any future diagnosis?
Stacey doesn't seem at all like the sort of person capable of looking after a dog with health issues.
If I were to take on a dog with a seemingly unexplainable small stature, you can bet I would be far more cautious that I would be with a normal dog.
Plus, as others have mentioned, the breed can be a nightmare for a few years. I doubt Stacey has done any sort of research past looking at some cute pictures and figuring out how to spin her latest story.
