What is Lymphoma in Dogs?

Lymphoma is a type of cancer that affects the lymphatic system in dogs. It is most commonly found in the lymph nodes, but can also affect the bone marrow, spleen, and other organs. Symptoms of canine lymphoma may include painless enlargement of the lymph nodes, decreased appetite, weight loss, and lethargy. Treatment may include chemotherapy, radiation, and/or surgery, depending on the type and stage of the cancer.

Canine Lymphoma Types

  • Non-Hodgkin Lymphoma: This type of lymphoma is most commonly seen in dogs and is divided into four main types: diffuse large B-cell, T-cell, mantle cell, and Burkitt lymphoma.
  • Hodgkin’s Disease: This type of canine lymphoma has both classical and nodular forms. The classical form is seen more often in young dogs but can occur in any age group.
  • Small Lymphocytic Lymphoma: This type of lymphoma usually affects older dogs and is comprised of small, round white blood cells.
  • Histiocytic Sarcoma: This type of canine lymphoma has two forms — primary and secondary. Primary histiocytic sarcoma arises from the lymph nodes, while secondary histiocytic sarcoma arises from metastasis to other organs.

Will A Dog With Lymphoma Die Naturally?

Yes, in some cases a dog with lymphoma can die from the disease naturally if allowed to live naturally. While most dogs will need to be treated for their lymphoma to live longer, some cases of aggressive cancers may be so advanced that natural death is a possibility. This is typically a more difficult course of action to undertake as this requires close monitoring and access to veterinary care to ensure that the dog is not suffering.

My Dog Has Lymphoma And Is Breathing Heavy

Lymphoma is a cancer of the lymphatic system, which is part of the immune system. The lymphatic system helps the body fight off infections. When your dog has lymphoma, it means that cancer cells have built up in the lymphatic system, leading to swelling and the inability of the body to fight infection. Your dog may be breathing heavily because of the excess fluid buildup at the site of the cancer, which restricts its lungs and makes it difficult to breathe. Other symptoms that may be associated with lymphoma include loss of appetite, weakness, lethargy, enlarged lymph nodes, and an increase in water consumption. If your dog is showing any of these symptoms, it is important to take them to the vet for a diagnosis. With proper treatment, many dogs with lymphoma can live a long and happy life.

What Causes Lymphoma In Dogs?

Lymphoma in dogs is caused by a type of cancerous cell called lymphocytes, which is a type of white blood cell found in the body’s lymphatic system. The most common type of lymphoma in dogs is a form of B-cell lymphoma, which is usually caused by the uncontrolled multiplication of B-lymphocytes. Other causes of canine lymphoma may include chronic viral infections, chronic inflammation, inherited genetic diseases, and certain breeds of dogs being predisposed to certain types of cancer.

How Common Is Lymphoma In Dogs?

Lymphoma is not an uncommon form of cancer in dogs. According to the American College of Veterinary Internal Medicine, lymphoma is the sixth most common cancer diagnosed in dogs, representing 6-7% of all canine cancers. In the United States, it is estimated that there are 40,000 new cases of lymphoma in dogs each year.

Symptoms Of Lymphoma In Dogs

  • Swollen lymph nodes
  • Loss of appetite
  • Lethargy
  • Weight loss
  • Excessive drinking and urination
  • Vomiting
  • Diarrhea
  • Difficulty breathing
  • Pale gums
  • Abdominal swelling
  • Spontaneous bleeding from the nose, mouth, or rectum
  • Bleeding from the skin
  • Poor coat condition

Stages Of Dog Lymphoma

  1. Initial diagnosis – During a physical exam, blood tests, or imaging, the veterinarian will diagnose the dog with lymphoma and begin outlining a treatment plan.
  2. Staging – A staging system is used to evaluate how far the cancer has spread. This helps the veterinarian and pet owners decide on a stage-appropriate treatment plan.
  3. Treatment – Depending on the stage of lymphoma, the treatment plan may include chemotherapy, radiation therapy, surgery, or a combination of treatments.
  4. Maintenance – Once the initial treatment is complete, the patient will enter maintenance mode. This involves regular monitoring and checkups, along with additional treatments such as diet changes or additional chemotherapy medications, to maintain stable disease.
  5. Relapse/progression – Unfortunately, lymphoma can recur or even progress despite treatment. It’s important for pet owners to keep a close watch over their pet’s health and well-being during and after treatment to catch any signs of relapse early.

Stage 5 Lymphoma In Dogs

Stage 5 lymphoma in dogs is the most advanced, and also the most difficult to successfully treat. Treatment options will depend on the type and stage of the lymphoma but may include chemotherapy, radiation therapy, surgery, dietary change, and immunotherapy. The best approach is to work with your veterinarian to create a treatment plan best suited for your dog’s particular situation.

What Are The Advanced Stages Of Lymphoma In Dogs?

The advanced stages of lymphoma in dogs are affected by the type of lymphoma. Generally, the most common stages are advanced or metastatic (spread to sterile organs and bones) and end-stage (when the cancer is no longer responding to treatment). In terms of signs and symptoms, advanced lymphoma can present with difficulty breathing, difficulty eating, vomiting, diarrhea, weight loss, fatigue, general discomfort, and fluid buildup around the abdomen. End-stage lymphoma is marked by the complete absence of response to treatment. Symptoms during this stage can vary significantly and can include pain, changes in behavior, anorexia, and further weight loss.

How Is Lymphoma Diagnosed?

Lymphoma in dogs is typically diagnosed through a combination of physical examination, medical imaging (x-ray, ultrasound, CAT scan), and laboratory testing. Depending on the clinical signs, a veterinarian may start by discussing the dog’s complete medical history, performing a physical examination, and collecting a blood sample. The blood sample is used to confirm a diagnosis of lymphoma by revealing an elevated white blood cell count or the presence of abnormal cells. Further diagnostic tests, such as fine needle aspiration (FNA) or biopsy, may also be performed to confirm the presence of lymphoma and help determine stage and type. During an FNA, a veterinary doctor uses a small needle to collect cells from the lymph nodes or other organs to test for the presence of lymphoma. A biopsy involves surgically removing a small portion of tissue to test for lymphoma.

  1. Make sure your dog has access to their favorite food and drinks: Dogs with lymphoma often experience a decrease in appetite and may need to be encouraged to eat. Offer your pup their favorite foods in small portions throughout the day and don’t forget to provide plenty of fresh water.
  2. Provide plenty of soft bedding and comfortable resting places: Choose bedding that’s gentle on your dog’s skin and not too firm. Cozy spots like a pet bed, blanket, or a pile of pillows will help keep your pup comfortable.
  3. Keep up with routine grooming: Regular brushing, nail trimming, and other routine grooming tasks can help your dog stay comfortable and reduce stress.
  4. Monitor your dog’s temperature: Be sure to take your pup’s temperature at least once a day as they may have fevers or bouts of chills. This can help the vet determine if the dog has any additional infections or any other underlying health issues causing them any trouble.
  5. Spend quality time with your dog: Spending time with your pup and providing gentle pats and snuggles can help ease their anxiety. Watching your favorite TV show together, going for short walks, or simply petting and cuddling can help provide comfort.
  6. Make a trip to the vet: Visiting the vet on a regular basis can help you both better monitor the condition of your pup and provide medical care to ensure your dog’s comfort.

Treatment Options And Lymphoma Life Expectancy In Dogs

For dogs with lymphoma, treatment options, and life expectations vary depending on the type and stage of cancer.

The most common treatment is chemotherapy, which is typically carried out over several months. In some cases, surgery, radiation therapy, and immunotherapy may be used in conjunction with chemotherapy.

Currently, the most reliable predictor of life expectancy in a lymphoma dog is the stage of disease at diagnosis. Dogs with stage I or II lymphoma typically survive 8–12 months after treatment begins, while dogs with stage III or IV lymphoma typically survive 4–5 months after treatment begins.

In addition to the stage at diagnosis, other prognostic factors influencing life expectancy in a lymphoma dog may include age, overall health, and type of therapy used.

Finally, a combination of lifestyle and dietary changes may help to improve a dog’s life expectancy, as well as their quality of life. Changes such as avoiding exposure to toxins, providing high-quality nutrition, and developing an exercise regimen can all benefit a dog with lymphoma.

Dog Lymphoma When To Euthanize

It is a very difficult choice to make, and each dog and situation is unique. Ultimately, the decision to initiate euthanasia should be made on a case-by-case basis in consultation with your veterinarian. Factors to consider include the dog’s overall quality of life, including the dog’s physical comfort, energy level, and ability to interact with its family. If the dog is suffering or no longer responding to treatment, then it may be time to consider euthanasia.

Q. How long is the end stage of lymphoma in dogs?

A. The end stage of lymphoma in dogs usually lasts between a few days and a few weeks. Treatment options, such as chemotherapy and radiation, can prolong life expectancy, but cannot cure the disease. Ultimately, managing the symptoms and providing supportive care is the best approach.

Q. What is the final stage lymphoma dog?

A. The final stage of lymphoma in dogs is the terminal stage of illness. At this stage, the cancer has spread to multiple organs and is considered terminal. Treatment options are limited and mostly palliative in nature. The goals of treatment at this stage include alleviating pain, managing symptoms, preserving quality of life, and providing comfort.

Q. How long can a dog have lymphoma before symptoms?

A. Lymphoma typically develops rapidly, so symptoms can appear quite soon after diagnosis. Generally, most dogs begin showing symptoms within a few weeks. However, some dogs can have lymphoma for months before any obvious clinical signs are seen.


The final stages of canine lymphoma can vary greatly depending on the type and progression of the disease. Symptoms such as weight loss, loss of appetite, lethargy, vomiting, and depression are common among dogs in the final stages, as well as signs of organ failure. As the disease progresses, treatments may not be effective, and the dog may begin to decline rapidly. Ultimately, talking to a veterinarian is the best way to assess a dog’s prognosis and plan for its end-of-life care.
