Please help cover Busters vet bills

Hi everyone, my big brothers dog got knocked over by a car on Monday the 20th of January. Because my brother was in such a panic just to get Buster to the vets he forgot to ask the car driver for his details to help cover the vet costs. He did try finding the driver on Facebook but had no luck. Buster has a broken leg, grazes on his face and legs and a gash under his chin. He has had an operation to fix his leg but the surgery alone has cost £3000 which is a lot of money for someone living on their own. We would be really grateful if you could donate and help cover Busters vet bills he is a brilliant dog and my brothers best friend he has literally kept my brother alive these past 3 years. The vet bills have caused a lot of stress for my brother as he's also got bills to pay but absolutely adores his dog, if you could help that would be very grateful and help ease the stress for my brother. Thank-you
