Help me help my Billy boy Campaign

Billy, my 7 year old Great Dane was diagnosed with Osteosarcoma on the 12th of August 2023, with a tumor on his hind leg but no visible metastasising to his lungs yet. Without conventional treatment (chemo/surgery) the vet gave him roughly 3 months to live as this is an extremely aggressive cancer. However, conventional treatment also does not have a good prognosis and would roughly add another 6 months to his life. So I set out to search for alternative treatment options. After consulting with many holistic practitioners, I opted to take him to Dr. Anita Schwan, a holistic vet in Pretoria, as she comes highly recommended for alternative oncology treatments.
