So sorry to hear about your puppy. My parents had a Golden Retriever Amber who developed oral cancer. She had two surgeries and they eventually had to have her put down when she was 7. They didn't want to put her through chemo or more surgery when she developed another tumor. It's so hard as they are such a part of the family. Good luck!
