How do I know if my dog has Lymphosarcoma?
Because lymphosarcoma is a disease that can affect many parts of the body, no one set of signs defines it. Many forms are first noticed when the dog becomes lethargic and loses weight and appetite. Some dogs may have one or more enlarged lymph nodes.  If abdominal organs are involved, the abdomen may be distended, and the dog may vomit. Other forms may cause coughing , drooling and difficulty swallowing. Your veterinarian will perform a thorough physical examination, feeling the abdomen, lymph nodes, listening to the lungs and chest, looking at the skin and in the eyes. He will also perform blood tests and possibly use radiographs and ultrasound to examine the chest and abdomen. Needle aspirates of lymph nodes may be useful in diagnosing lymphosarcoma.  Or aA bone marrow aspirate may be performed to determine how advanced the disease is.

What can I do about Lymphosarcoma?

Several chemotherapy protocols are in use; your veterinarian may wish to confer with a veterinary oncologist, or refer you to one, for the latest protocol.
