Amputation Surgery for Roxy

For those who don't know, Roxy was recently diagnosed with Osteosarcoma of her femur. The treatment plan at this stage is amputation surgery or euthanasia. 
With the immense treatment cost for the surgery and stay I am looking to the public for help with costs for the surgery. This will allow for her to receive the care and extended life she and I are looking for.
ANY help is appreciated and will make a huge difference.
