Symptoms
There are many symptoms of canine lymphosarcoma that you should be aware of. The most common include a lack of energy, enlargement of the lymph nodes, and difficulty breathing. If canine lymphosarcoma affects the gastrointestinal system, your dog may also experience vomiting or diarrhea. Other symptoms include pale mucous membranes, decreased appetite, increased thirst, and increased urination.
Diagnosis
To diagnose canine lymphosarcoma, the veterinarian will usually take a blood sample to perform tests. It may also be necessary to take x-rays and perform a physical exam. A biopsy may also be needed to confirm the diagnosis of canine lymphosarcoma.
Treatment
The main goal of treatment for canine lymphosarcoma is to force the cancer into remission initially and during subsequent relapses. The main treatment for this disease is chemotherapy because this cancer usually occurs throughout the body. The chemotherapy drugs commonly used include prednisone, vincristine, doxorubicin, and cyclophosphamide. If the canine lymphosarcoma only affects a localized area, your dog may also benefit from surgery or radiation therapy in addition to the chemotherapy.
