November marks Canine Lymphoma Awareness Month, an important time dedicated to educating dog owners, veterinarians, and pet lovers about one of the most common cancers affecting our four-legged companions. National Canine Lymphoma Awareness Day stands at the heart of this initiative, shining a spotlight on the disease’s prevalence, risk factors, and potential treatments. Lymphoma, which involves the lymphatic system, affects thousands of dogs every year and can manifest in various forms, including multicentric, gastrointestinal, and mediastinal types. By understanding the signs—such as swollen lymph nodes, loss of appetite, and lethargy—pet owners can promptly seek veterinary care and improve their dog’s prognosis. Veterinary oncologists emphasize that early detection, coupled with appropriate therapy, can significantly prolong a dog’s overall quality of life. During this dedicated month, raising awareness helps further crucial research initiatives and fosters greater hope for dogs diagnosed with lymphoma and the families who love them.
November 7th is National Canine Lymphoma Awareness Day. Canine lymphoma is one of the most common cancers often found in dogs. In fact, it could make up as many as 20 percent of canine cancer cases. A local vet discusses canine lymphoma below.
Basics
While any dog can be affected, and at any stage of their life, it’s most often seen in dogs that are middle aged or older. It does seem to be more prevalent in specific breeds. Golden Retrievers, Basset Hounds, Boxers, Bull Mastiffs, Saint Bernards, Scottish and Airedale Terriers, and Bulldogs may be predisposed. Lymphoma can affect any organ in Fido’s body. However, it is usually found in spots that are associated with the immune system, such as the spleen, liver, bone marrow, or lymph nodes.
Symptoms
Lymphoma is quite complex: there are over 30 different types, all of which affect dogs’ bodies in different ways. The symptoms can also vary quite widely, depending on what organs are affected and how far the cancer has progressed. Some of the common ones include trouble breathing; lack of appetite; weight loss; vomiting; diarrhea; increased water intake; fever; swelling, particularly around the neck, throat, and knee joints; and fever. Some dogs don’t experience any of these symptoms at all. Sometimes the owner will notice a strange lump, bump, or lesion. Of course, these things can be indicative of many different health issues in our canine pals. They all would warrant a call to the veterinary clinic to schedule an appointment ASAP. It’s also important to consider zoonotic diseases; read more about this in “You Can Catch These Diseases From Your Dog.” As with many other health issues in dogs, early diagnosis and treatment are always beneficial. In the case of canine lymphoma, addressing the issue early on can increase the chances of treatment extending Fido’s life and/or causing the cancer to go into remission.
Treatment
National Canine Lymphoma Awareness Day brings attention to a significant type of canine cancer—lymphoma, which is notably treatable with advancements in veterinary medicine. In fact, it’s one of the more treatable types of canine cancers. Modern veterinary medicine is making some truly wonderful advances in this area. As far as treatment options, chemotherapy is the most common treatment. Your vet may also recommend surgery and/or radiation; alternative treatments, such as holistic options; and/or newer treatments. Of course, specific treatment options are always offered on a case-by-case basis, once a full diagnosis has been made. For detailed diagnostic services, consider our “Veterinary Diagnostic Laboratory” which provides comprehensive tests to help determine the best course of action. Your vet will be able to offer specific options after Fido’s tests and lab results have come back.
National Canine Lymphoma Awareness Day 2025: Treatment and Survival Insights
How do dogs typically tolerate chemotherapy compared to humans?
Chemotherapy protocols in dogs typically result in fewer severe side effects than those often seen in human cancer patients. Veterinarians aim for a balance that maintains the animal’s quality of life, so drug dosages are generally lower, and treatments are adjusted to minimize discomfort. Mild vomiting, diarrhea, and transient lethargy may occur, but these effects are usually manageable with supportive care. Most dogs can continue normal activities and retain a good appetite during treatment. Overall, canine patients often have a less distressing experience, making it a viable option to prolong remission or manage progression.
What is the average survival rate for untreated dogs after diagnosis?
Survival rates for dogs with untreated lymphoma are typically short, often around four to eight weeks from diagnosis. This timeframe can vary depending on the stage of the disease and overall health. Some may experience a slightly longer period, while others deteriorate more quickly. Without medical intervention, symptoms can escalate, leading to reduced quality of life. Prompt diagnosis and chemotherapy, in many cases, can offer extended remission. Although lymphoma remains a serious concern, increased awareness of available treatments provides better odds of prolonging a dog’s comfort and companionship. Early intervention significantly impacts outcomes, emphasizing the advantage of prompt veterinary care.
What are the potential environmental causes of canine lymphoma?
Potential environmental factors linked to canine lymphoma can include exposure to pesticides, herbicides, or other carcinogens. Some studies have pointed to secondhand smoke, industrial pollutants, and certain household chemicals as potential triggers. Prolonged contact with these substances may disrupt immune function, increasing susceptibility to lymphoma. Although genetic predisposition also plays a role, limiting known carcinogens in a dog’s surroundings may help reduce overall risk. Additionally, routine checkups and careful observation can catch early signs, offering better outcomes. Awareness of breed predisposition also contributes to a proactive approach. Regular cleaning of living areas and proper disposal of chemical products help minimize harmful exposures.
How do these newer treatments compare to traditional chemotherapy?
Newer treatments, such as immunotherapies, targeted drugs, and integrated regimens, can complement or replace standard chemotherapy. Traditional chemotherapy is widely used and effective but can occasionally result in side effects like reduced appetite or lowered energy. More innovative options may offer fewer adverse reactions, while still helping reduce tumor size or prolong remission periods. The ability to specifically target cancer cells can limit damage to healthy tissue, though outcomes can vary among individuals. Combining updated approaches with or without chemotherapy may enhance overall effectiveness. Ongoing advancements continue to expand the range of canine lymphoma treatment possibilities.
How is lymph node fluid analysis used in diagnosis?
Lymph node fluid analysis involves obtaining a sample, typically through fine-needle aspiration or biopsy, and examining it under a microscope for abnormal cells. Pathologists often look for morphological changes, such as enlarged lymphocytes or cancerous clusters that signal lymphoma. This approach is central for distinguishing lymphoma from infections or benign conditions. Additional tests, including flow cytometry and specialized staining, can also identify specific lymphoma subtypes. By identifying malignant cells early, lymph node fluid analysis guides treatment decisions and can significantly improve prognosis when combined with prompt intervention and supportive care.
