Dogs with multicentric lymphoma may also develop lethargy, fever, anorexia, weakness, and dehydration as the disease progresses. Dogs with alimentary lymphoma, which affects the intestines, may present with vomiting, abdominal pain, anorexia, diarrhea, and weight loss.
If left untreated, dogs with lymphoma will generally die from their disease within 3 to 4 weeks. Treatment with prednisone (a corticosteroid) alone generally can induce short-lived remissions (usually less than 8 to 12 weeks), but this treatment can make the disease resistant to other treatments.
Stage I and II are rarely seen in dogs, while Stages III-V are more common.
- Stage I: involves only a single lymph node.
- Stage II: involves lymph nodes on only one side of the diaphragm (only affects the front of the body or rear of the body)
- Stage III: generalized lymph node involvement.
Steroids, glucocorticoids, cortisone, and prednisone are all names for the same type of drug. In lymphoma, steroids kill the cancer cells but are not ”traditional” chemotherapy agents. Treatment with a single chemotherapy drug, most commonly doxorubicin (Adriamycin®), although others can be used.
Some progress rapidly and are acutely life-threatening without treatment, while others progress very slowly and are managed as chronic, indolent diseases. Lymphomas may affect any organ in the body, but most commonly originate in lymph nodes, before spreading to other organs such as the spleen, liver, and bone marrow.
There are many things you can do to care for your dog as she receives treatment, including:
- Stay in regular contact with your veterinarian.
- Feed your dog when he will eat.
- Assist her with getting around.
- Provide exercise and play based on your vet's recommendation.
- Allow plenty of time for petting and grooming.
Without treatment the life expectancy in dogs with lymphoma is 1-2 months. With treatment, in dogs that feel well, about 80% – 90% of dogs with lymphoma attain a complete remission with an average survival of 12-14 months.
In general, dogs with lymphoma tend to survive a very short period of time without treatment—only around two to three months. However, lymphoma is a type of cancer that usually responds well to chemotherapy.
Non-Hodgkin lymphoma grows and spreads at different rates and can be indolent or aggressive. Indolent lymphoma tends to grow and spread slowly, and has few signs and symptoms. Aggressive lymphoma grows and spreads quickly, and has signs and symptoms that can be severe.
In the end, chemotherapy is not done commonly. But it's worth a discussion if you find that your old companion has been diagnosed with cancer. For some folks, four to six months of happy mornings and nudged elbows are worth it. Cost is a deal breaker for a lot of people, but nothing to be ashamed about.
Prognosis. Without any treatment, the average survival for dogs with lymphoma is 4 to 6 weeks. Approximately 50% of dogs with lymphoma will respond to prednisone (a steroid) alone, but the remission times are only 2 to 4 months with prednisone alone.
When you kiss your dog, you may notice signs that indicate they know that the kiss is a gesture of affection. As puppies, this is not something that dogs would recognize, although they would feel you doing it. Of course, dogs don't know what kisses actually are, but they learn to realize that they are good.
This is the last and most heartbreaking of the main signs that a dog is dying. Some dogs will know their time is approaching and will look to their people for comfort. with love and grace means staying with your dog during these final hours, and reassuring them with gentle stroking and a soft voice.
Prednisone (a cortisone) is the most commonly used drug for therapy of mast cell tumors. It is well tolerated by dogs and is usually employed for a minimum of six months. If no new tumors appear within that time, your doctor may wean your dog off the prednisone completely.
Long Term Side EffectsWith long term use of prednisone, dogs may also experience poor wound healing and muscle weakness. They may develop hard plaques or spots on their skin called calcinosis cutis. Due to increased hunger, dogs may develop a tendency for obesity.
In a few cases, chemotherapy may be combined with steroid medication. Surgery isn't generally used to treat the condition, except for the biopsy used to diagnose it. Overall, treatment for Hodgkin lymphoma is highly effective and most people with the condition are eventually cured.
A standard course of chemotherapy costs between $3,000 and $5,000, and radiation treatments used for brain and nasal tumors run between $6,000 and $10,000.
How To Help Your Dog Avoid Cancer
- Work with a breeder who screens for cancer to minimize the genetic risk.
- Decisions involving spay-neuter and diet maintenance can help limit cancer risk.
- Avoid environmental risks like cigarette smoke, toxic chemicals, and excessive sunlight.
A bone marrow aspiration and biopsy procedure involves inserting a needle into your hipbone to remove a sample of bone marrow. The sample is analyzed to look for lymphoma cells. Imaging tests. Your doctor may recommend imaging tests to look for signs of lymphoma in other areas of your body.

Malignant lymphoma is a common cancer in dogs. It is a progressive, deadly disease caused by the harmful growth of lymphocytes. Lymphoma most commonly arises from lymphoid tissues in the bone marrow, thymus, lymph nodes, or spleen. Other common sites include the skin, eye, central nervous system, and bone.
The first week of treatment, known as Induction, is often a happy week as most lymphoma dogs feel great being on prednisone at 30 mg/M2 PO q24h for 7 days. This shrinks the nodes and stimulates the appetite.
Without any treatment, the average survival for dogs with lymphoma is four to six weeks. Approximately 50 percent of dogs with lymphoma will respond to prednisone (a steroid) alone, but the remission times are only two to four months.
Abnormality or enlargement of the lymph nodes is called lymphadenopathy. This can be caused by many different diseases, including bacterial or fungal infection, and cancer.
If the tumor is small or restricted to the local area, the dog is a good candidate for surgery. If there is spread to a lymph node, surgery may include removal of that lymph node and chemotherapy may be recommended after the surgery.
Lymphoma in dogs. Lymphoma is one of the most common malignant tumors to occur in dogs. The cause is genetic, but there are also suspected environmental factors involved, including in one study an increased risk with the use of the herbicide 2,4-D.
Lymphoma is a cancer of the cells of the immune system called lymphocytes. Lymphocytes are present throughout the body, so dogs can develop lymphoma in multiple organs. Lymphoma most often affects lymph nodes, but can also affect the liver, spleen, bone marrow, and other sites.
