Help Rusty get to vet

Hello, I'm Cindy. I need help to get Rusty, my recently deceased father's dog, to the vet. Ends have been tight with his recent passing, and Rusty needs some medical attention for his back legs. He needs surgery to help with mobility as they're giving out of him as of late. His health has gone downhill ever since the passing of his owner. All the money he gathered will go into his vet bills, and anything else needed. So please, if you can donate or even spread this around, it will be much appreciated.
