http://www.facebook.com/tracy.b.ash.7 I have a ton of dog lovers and advocates on my friends list and between all of us we can make sure that this greeders business dries up to nothing, if she chooses not to make things right. I sincerely hope that she at least offers you a refund, though that won't help your broken heart. At least you would recoup some of the funds spent at the vets/specialists. Bad breeding makes me so ill, and this is why, nice people and innocent animals suffering
You and Maggie are in my thoughts and prayers
