Please help me save Sage

Hi, my name is Ron and I am disabled senior desperately seeking funding to save my best friends life. About a year and a half ago my 11 year old beloved bullmastiff died, and shortly after that, thanks to the kindness of a breeder, Sage came into my life. Sage is a big loveable, goofy 22 month old Cana Corso crossed with a Maremma Sheepdog, a 115 pounds and still growing. He is my best friend and constant companion. I can't emphasize enough how important he is to me. Because of my disabilities, I spend a lot of time alone with him as my only companion. A few days ago, Sage ate a small square plastic container, and he has not been able to pass it. Sage urgently needs veterinary care, but I can't afford to pay for the examination, X-rays and surgery to remove it. I don't know what I will do if I lose Sage, and I don't have much time. The only other alternative will soon become euthanasia, and I really couldn't stand to lose him. Any assistance you can provide will be forever appreciated. Thank you!
