Dogs with stage 4 canine lymphoma are treated using multi-agent chemotherapy, according to Advanced Veterinary Care Center. Unlike in the treatment of human cancer patients, the goal of chemotherapy in dogs is to induce remission rather than cure. In stage 4 cases, this figure is around 60 to 80 percent.
The particular stage of canine lymphoma is not considered an especially consistent predictor of remission, states Advanced Veterinary Care Center. The best predictor is whether or not the dog feels well before diagnosis. Side effects of chemotherapy in dogs are not common but include vomiting, diarrhea and lack of appetite. Dogs that do not undergo treatment for lymphoma are expected to live between four to six weeks.
