Help With Luna's Surgery Vet Bills

Hello all, 
Luna is our 3 year old Weimeraner dog and recently had to go thru a much needed leg amputation. She was born without a wrist bone that the vet deemed a congenital deformity. Instead of a wrist bone she had a thickened piece of cartilage that was trying to support her arm bone, and unfortunately after 3 years gave out. Causing her paw to become clubbed and her bones to bust thru her skin. It was a painful sight and she was constantly getting infections. We are needing some help to cover her surgery bills as this was emergency surgery that she needed to better her life 
We appreciate any help that anyone can give us.
Thank you for your time!
