Please help Bambi

Hi everyone, a dear friend has ended up with a pup that has her leg broken in four places. We are not sure how this happened to her. The owner was going to put her down. She is a beautiful girl. Has been to the vet and they have said she would need to have her leg amputated or have surgery. We would love not to amputate. Please if you can help with the smallest amount, it would be much appreciated.
