Lung lymphoma in dogs is not rare, affecting 15-20% of dogs diagnosed with cancer. It impacts the lymph nodes and lymphatic system. It can develop in the lungs too. Dogs can get one of four lymphoma types: multicentric, alimentary, mediastinal, and extranodal.
This cancer starts when lymphoid cells grow uncontrollably. It can hurt different parts of the body. Dogs with the most common form, multicentric lymphoma, will have swollen lymph nodes. They might also lose weight, feel tired, have stomach issues, and breathe hard.
To find out if a dog has lymphoma, vets do tests. They may sample affected tissue or lymph nodes. They also see how far the disease has spread.
The main way to fight this cancer is with chemotherapy. Sometimes, vets use surgery or radiation. The CHOP protocol, a 25-week chemo plan, often works well. It can lead to remission, where the cancer shrinks or disappears, in many dogs.
How well a dog with lymphoma does depends on the cancer type and stage. It also depends on the treatment. With good care, dogs can have months or more of quality life. Catching the cancer early and regular vet visits are key.

What is Lymphoma?
Lymphoma is a cancer type that affects dogs’ lymph nodes and lymphatic system. It can start as a small tumor or spread everywhere, posing serious threats. The lymphatic system helps move fluids and plays a key role in fighting off diseases. It includes lymph nodes, the spleen, tonsils, and a network of vessels.
About 15-20% of all new cancer cases2 in dogs are lymphoma. Certain breeds like Chow Chows, Golden Retrievers, and German Shepherds are more likely to get it2. This shows that genetics might play a part in this cancer.
It’s important to know about lymphoma’s four main types in dogs. Multicentric lymphoma is the most common, affecting many lymph nodes2. About 80-85% of lymphoma cases are of this type. Alimentary lymphoma targets the gastrointestinal tract, and mediastinal lymphoma impacts the chest organs. Extranodal lymphoma strikes organs outside the lymphatic system, like the skin or eyes2.
The symptoms and how severe lymphoma gets can vary. It depends on the cancer type and how far it has spread. Being able to spot the signs early is crucial. Early detection means better chances for the dog’s treatment and recovery.
Common Signs of Lymphoma in Dogs
Dogs with lymphoma show different symptoms based on the lymphoma type and affected organ. The most common lymphoma in dogs is multicentric lymphoma, making up 80-85% of cases.
The main sign of multicentric lymphoma is swollen lymph nodes. This swelling often shows in the neck, chest, armpits, groin, and behind the knees. Pet owners should check their dogs for any lumps in these areas regularly. Swollen lymph nodes can be an early sign of lymphoma.
Dogs with this lymphoma may lose weight, feel weak, and have stomach issues. They lose weight because the disease changes how the body uses nutrients. They might also lack energy and enthusiasm.
Some dogs might have vomiting and diarrhea due to alimentary lymphoma. This type affects the stomach and leads to inflammation, causing these symptoms.
Mediastinal lymphoma might cause trouble breathing, swelling in the face or legs, and make dogs drink and pee more. It affects lymphoid organs in the chest, changing the respiratory system and fluid balance.
Extranodal lymphoma hits different organs outside the lymph system, causing various symptoms. It’s important for owners to watch for any new or unusual behaviors or changes in their dog’s look that could mean lymphoma.
Spotting lymphoma early is key for effective treatment and a better chance of recovery. If owners see any of these signs, they should take their dog to a vet for more tests and help.

Diagnosing Canine Lymphoma
When a dog might have lymphoma, vets start with tests. If a dog’s lymph nodes are swollen, it could mean lymphoma. But, vets need more tests to be sure.
To check closer, a fine needle aspirate test is often done2. A vet uses a needle to take cells from the lymph node to look at under a microscope2. If this test doesn’t give clear results, a biopsy might be needed2.
Vets also do bloodwork to see how the dog is doing overall2. They might do more tests to learn about the lymphoma type and how much it has spread2.
| Stage of Lymphoma | Statistical Data |
|---|---|
| Stage I and II | Not often seen in dogs2 |
| Stages III-V | Usually found in dogs2 |
Dogs can have lymphoma in five different stages, from one lymph node to many organs2. The stage helps vets decide the best treatment.
Canine Lymphoma Treatment Options
Treating canine lymphoma offers several choices. It depends on the disease’s kind and phase. Chemo is the main way we fight lymphoma in dogs. It uses a mix of drugs given through shots at certain times. Dogs usually handle chemo well, facing only minor problems like throwing up, diarrhea, and eating less. It’s the top treatment for many lymphoma types, with 70-90% of dogs getting much better. Most dogs can fully recover with chemo1.
For some lymphoma that hasn’t spread much, surgery or radiation might be suggested. But, these are not as effective as chemo and are used in special cases. These methods can remove or target tumors in certain places. They help keep the disease from getting worse. Every dog’s situation is unique, so it’s important to talk to a vet oncologist to figure out the best plan2.
If chemo isn’t an option because of the dog’s condition or cost, prednisone is another route for comfort care. This type of care aims to better life quality by lessening lymphoma’s symptoms. Prednisone can ease symptoms and make dogs with lymphoma more comfortable. However, it’s key to remember that comfort care doesn’t cure the cancer and won’t lead to long-term recovery2.
Choosing the right treatment involves considering the lymphoma’s type and stage, along with the dog’s health and needs. Getting advice from a vet oncologist is key. They help create a custom treatment plan. This plan is the dog’s best shot at remission and living longer2.
Prognosis for Canine Lymphoma
The outlook for dogs with lymphoma changes based on the disease’s type, stage, and treatment. On average, dogs with lymphoma live about four to six weeks2 if they don’t get any treatment or just take prednisone. But with chemotherapy, many dogs go into remission and live longer.
Remission means the signs of lymphoma are gone for a while. Dogs in remission after chemotherapy usually enjoy eight to nine months2 of good life. Remember, these numbers are averages. Each dog’s situation can be different.
For dogs facing a type of lymphoma known as multicentric, the CHOP protocol is a common treatment. It helps many dogs enter full or partial remission1.
About 70-90% of dogs treated with the CHOP protocol see their lymphoma go into remission. This greatly extends their lives.
Lymphoma in dogs is complicated, and several things can affect the outcome. These include the lymphoma’s type and stage, the dog’s health, and how well they respond to treatment. Though average statistics21 offer some insight, it’s best to talk with a vet. They can give a detailed plan and outlook for your dog.
| Treatment | Average Survival Time | Remission Period |
|---|---|---|
| No treatment or prednisone alone | 4-6 weeks2 | N/A |
| Chemotherapy | Approximately 1 year2 | 8-9 months2 |

Canine Lymphoma Types and Causes
Canine lymphoma is a type of cancer that can be confusing due to its different forms. By knowing these forms, vets and pet owners can choose the right steps early on. The common kind found in dogs is multicentric lymphoma, making up 80-85% of cases2. This kind primarily targets the lymph nodes across the body, leading to swelling and symptoms.
Another is cutaneous lymphoma, focusing on the skin. Affected dogs might show signs like dry, flaky skin or sores1. Gastrointestinal lymphoma targets the stomach or intestines causing vomiting, diarrhea, and weight loss1. There’s also mediastinal lymphoma in the chest area, causing breathing issues and swelling1. Extranodal lymphoma affects different organs, showing varied symptoms based on the organ it hits2.
The exact causes of lymphoma in dogs aren’t totally known, but many factors might contribute. Things like genetic makeup, infections, and harmful environmental exposure might play a part. Scientists are still working to understand this disease better.
Symptoms and Diagnosis of Canine Lymphoma
Canine lymphoma shows up in many ways, helping us know it’s there. One major sign is swollen lymph nodes in dogs. These can feel like bumps under their skin in areas like the neck and behind the knees2. Dogs might eat less and lose weight because the cancer affects their whole body and how their organs work3.
Keep an eye out for coughing and swelling in the face or legs too2. Lymphoma has different types, each with unique signs. For example, some dogs get dry skin or ulcers, while others have stomach problems3.
When a vet thinks a dog might have lymphoma, finding out for sure is key for figuring out treatment. The go-to way to check for lymphoma is a biopsy, where a small bit of tissue is tested3. Vets also do other tests to see how far the cancer has spread. These tests help decide the best treatment plan2.
Common Symptoms of Canine Lymphoma:
- Enlarged lymph nodes
- Decreased appetite
- Coughing
- Swelling of face or limbs
It’s important for dog owners to watch their dogs for these signs and get vet help if lymphoma is suspected. Finding it early can mean better options for treatment. Vets play a vital role in pinpointing lymphoma and helping owners know what steps to take next.
| Types of Canine Lymphoma | Prevalence |
|---|---|
| Multicentric lymphoma | 2 80-85% of lymphomas in dogs |
| Cutaneous lymphoma | Varied prevalence |
| Gastrointestinal lymphoma | Less than 10% of canine lymphomas |
| Other types (mediastinal, extranodal) | Varied prevalence |
