Sammi, my little Jodie Foster is a rescue girl, surrendered by a byb. She is ten yo, bred for 7 years, and she has a sway back too. It's probably related to being overbred, but I couldn't say for certain. I would imagine, just like with our bodies changing after having babies, a yorkie after years of having babies, body would change.
I just hope the little girl didn't have puppies somewhere that needed her. If the yorkie came from a puppymill, it's possibly she is microchipped. Your friend might want to have her scanned.
Bless your friend for saving her and you for helping her out.
