I know it's hard with all the problems you've been having with her but she really needs to see a vet. I'd probably go to another vet for a second opinion.

I know it's not your fault, but your mother should of really thought this through before getting a new puppy. She should of had enough money set aside should an emergancy arise (like this one). It's too bad.

I can't offer any advice as you really need to get her to the vets but I do wish you the best of luck with her.

Have you contacted the breeder at all? I know she is from a BYB, but still I'd be on their ass day & night, over & over again until something is done. I'd be pounding them about their negligence on breeding such poor specimans. You'd bet your bottom dollar I'd be getting something out of them, at least some help on determining what is wrong & how to correct it. If there was any type of warranty (which there should of been for that price!!) I'd be getting them to pay for every dollar spent at the vets. Really, you need to let them know that their breeding habits are absolutely terrible. You need to get the word out. Report them to your local vet offices (even the ones you don't go to), to the shelters etc... to let them know about all the problems. Even if they can't do anything about it it will at least warn others not to buy from them.
