HELP CHIKARA THE RESCUE PUPPY

A friend of mine purchased a puppy from a breeder at 8 weeks old.. on the collection of her puppy she noticed its sibling wasn't well and once asked what was wrong with the puppy the breeder had said she was being sick for a week and he was having her put to sleep the next day as he couldnt pay for her vet bills.. She contacted me and I offered to take her and pay the bills (i rescue and rehome from home and pay for their care myself) after 2 operations and 2 weeks in the vets they have asked to send her to Earlswood vets in Belfast as they have no idea what's wrong with her. Earlswood vet charge over £100 just for a consultation and I can't afford it. I've already payed over £500 towards her vet care, Earlswood dont do payment plans and she will need scans and medications so it's really her last chance at life as if i cant pay then she will have to be put to sleep.. anyone who's met her knows she so full of life.. shes just 10 weeks old, the issue is she cant keep food down but with specialist care we will know how serious her condition is
