I ASK FOR HELP WHO CAN HELP US IN THIS CASE OF MY SICK PET. EM CAMPINAS

My puppy is a 6 and half years old and has been diagnosed with osteoblastic sarcoma (pelvis) and is being treated with chemotherapy, but the disease is progressing. I ask that a chain be formed in favor of her that has not even reached half life for those who love animals and São Francisco de Assis. Something new that can help her, she can't stand up anymore and can't walk currently, beeing too with difficulty to do the needs anymore. Someone do something for her in name of Lord because I, her tutor, am in a state of despair, not resigned with this situation that is happening to us. Thank you to whom can give us some light right now.
