Charlie's amputation

Hi, my dogs name is Charlie and she just broke her leg yesterday playing at the park doing her favorite thing.. Fetching tennis balls! Unfortunately she hit a wheel chair ramp and had an accident that left her leg broken in multiple places. The vet's say we need to amputate and the cost is roughly $4500. Worst case is we would have to put Charlie to rest if we can't afford the procedure. We really love our family golden retriever and all the help and love you can give will help us keep our beloved dog.
