Save Bear, treatment for Nasal Cancer and meds

Bear will be starting radiation Friday July 17th. Bear has been part of our family since he was 4 weeks old. We have bottle fed him and he has help us raise all of our other pets. When my husband was at his sickest he was always right there for him. He never left his side during PTSD, depression, anxiety, sickness and in health. When he came home from the military he was a savior for him even though it was a few years later. He was there when I had my own surgeries and he helped my mother in-law through all her chemo and radiation treatments.  Unfortunately it is now our turn to try to help him. Bear has been diagnosed with a nasal tumor on 06/25/20.  In the beginning of May we kept seeing droplets of blood around the house on the floor, which we though he was catching his nails on our new tile. I went out and bought carpet and l laid that down. The day I laid the carpet was the day we noticed blood coming from his nose as he sneezed.  Even with the blood there was no change in activity. He is still eating, drinking, playing and running as is he were a puppy.  We took him to the vet and he was placed on a nose drop to stop the bleeding but the bleeding did not stop. A few days later we took him the ER and they scheduled him for a rhinoscopy, which showed the tumor. Again no change in activity. He is currently taking a Herbal Supplement which seems to be helping with the bleeding, and we are awaiting pathology results to find out what kind of tumor it is. We do have the option to shrink the tumor through radiation and holistic treatments.  Unfortunately it is going to be hard to come up with the money to do treatments. We usually don't ask for anything. We always try to figure out what to do as any parent would. The treatments will cost anywhiere from $8,000 to $12,000.  We are hoping to start treatments as soon as possible!  We are just asking that if you can help, you do. Any amount would be awesome but not required.  This is our baby, as we are unable to have kids of our own. It would mean the WORLD to us to be able to help him like he has always helped us. We would be forever grateful to be able to give him the rest of his years!
