According to me, chemotherapy and dogs food diet control is the best way to control the cancer.
We owned a Labrador Retriever who was diagnosed with cancer at 11 years of age. We decided to treat with chemotherapy which she responded to very well at first. She had all five treatments, the last two really seemed to weaken her (she bounced back less quickly from them). The cancer did not come back (to our knowledge) within the 5 months that she was on the treatments. We had to put her down within 6 months of her diagnoses. I don't know if we would do chemotherapy with a dog again.
I had an Australian Cattle Dog that was diagnosed with liver cancer. After discussing options with the vet, who recommended surgery and radiation, we decided instead to forgo the treatment, and we put her down a few months later when she was in constant pain. While the treatment could have extended her life, and we loved her very much, it was thousands of dollars and she was already eleven. At most it would have only given us another two years or so, and we just could not justify it.
Cancer most often strikes older dogs. I feel that the best treatment is to be as loving as possible and to keep the dog as comfortable as possible. The pain and stress of aggressive medical treatment for cancer is not warranted for an older pet who has had a happy life. A much better and kinder approach is to allow the pet to live out her remaining days with dignity and love which includes allowing the dog to pass when the time comes.
