Daisy's tumour removal operation

Hi, I'm Jake and I'm trying to raise enough to pay for daisy the dogs cancer treatment, I have contacted several dog charities who all can't help me, and although I'm eligible for the PDSA at one end of my world and the Blue cross vets at the other neither are currently taking on new patients so here I am at a loss as to how else to help my dog, I've sold things and taken on extra work where possible but it is still not enough. Please give anything you can, even if it's only a pound or two as every little helps.
