Please help us mend Shadow's broken leg. Shadow was found locally and taken to Whitby Dog Rescue. He is microchipped but the owner's details have not been updated. Shadow is a lovely dog but has a compound fracture in his right front leg.

He also has a fractured jaw. Legally we cannot operate on him until Friday. The operation will cost £3,500; the charity cannot afford this, but want to try and save Shadow's leg, rather than opt for the cheaper option of amputation, as he is a young dog and has a lovely temperament. Can you help?
