I'm SO hoping you can keep her and make small payments - They must be able to tell you love her.
Is it a small pet store ?? Can you go in there with ALL your paperwork and go thru things step by step - and get the breeder involved too ??? I wish I could help financially - I really do ...this sounds like such a strange thing to happen but I sure couldn't return a dog after bonding
......
HUGS and I really hope someone has ideas for you here - people are so good about helping ...Can't they keep the deposit money and put it towards her purchase without returning her ?
