Clearly you and Bailey are fighters of some great strength. In some ways I have been where you are - $6000 later I had a healthy dog who lived 11 wonderful and loving years.
I agree with MauiGirl when she said save Bailey and deal with the breeder later.
You are constantly in the thoughts and prayer is YT folks here and we do have prayer power here
Keep us posted and all you can do is the best you can!
