In dogs, the lymphatic system contains both the lymph nodes and vessels. These are spread throughout the canine body in many different areas including, but not limited to, the arm pits, the neck, the gastrointestinal tract and the groin area. The lymphatic system is part of the immune system and is important for fighting disease or illness. Lymphoma can occur anywhere in a canine body, including the intestines.

Location
-
Intestinal lymphoma can affect either the upper intestines or the lower intestines. It can also occur as a secondary cancer that has occurred following the spread of cancer cells through the lymphatic system from other areas in the body such as the gastrointestinal tract. This includes the stomach, the liver and other lymph nodes or lymph vessels.
Symptoms
-
Symptoms of canine intestinal lymphoma can vary from dog to dog. Many times the affected dog suffers from changes in appetite, including a total lack of appetite. This change can lead to malnutrition, resulting in weight loss and an overall decline in health for the affected dog. Many dogs also experience vomiting or diarrhea, depending on the exact location of the lymphoma. As with any cancer, you may notice certain behavioral changes, such as depression or becoming lethargic.
Diagnosis
-
Several tests are needed to confirm a diagnosis of canine intestinal lymphoma. Aside from a physical exam, the canine will undergo a fine needle aspirate of the affected area. The vet will take samples and analyze them beneath a microscope to identify the cells or look for other health issues, such as bacteria, which may be causing the symptoms. In addition, the dog may also need to undergo additional biopsies to determine if the cancer has spread to other areas of his body.
Treatment
-
Treatment options for intestinal lymphoma in a dog include surgery, chemotherapy and radiation therapy. If the tumor is accessible, surgical removal may be an option. Chemotherapy, coupled with radiation therapy, may be a better option. Fortunately, chemotherapy seems to be an extremely effective treatment against lymphoma in canines. Intestinal lymphoma may also benefit from improved nutrition. For example, foods that are higher in protein and Omega 3 fatty acids are ideal for dogs suffering from any form of lymphoma.
Prognosis
-
Many owners are relieved to know that lymphomas of any type have a high rate of remission and survival. According to an article by Dr. Kimberly Cronin of Pet Place, up to 90 percent of dogs who receive the appropriate treatment will go into remission and survive for an additional year. Meanwhile, up to 15 percent of these dogs will continue to live for two or more additional years.
