CBD Oil for Dogs with Lymphoma: A Guide To Care For Dogs With Cancer

For pet owners, a lymphoma diagnosis in their dogs is heartbreaking and—let’s be honest, pretty overwhelming. This common form of canine cancer targets the lymphatic system, a key part of the immune system, and brings symptoms and treatments that leave both dogs and their humans in need of some relief. “Canine lymphoma is a common type of neoplasia in dogs, with an estimated incidence rate of 20-100 cases per 100,000 dogs, similar to non-Hodgkin lymphoma in humans,” (Zandvliet, M., 2016).

CBD oil is a natural supplement that’s been making waves for its potential benefits in supporting dogs with lymphoma. Dive into how CBD oil becomes a go-to tool in a pet care toolkit, giving a furry friend the comfort and care they deserve.

Lymphoma in Dogs: The Basics

Lymphoma in dogs is a cancer of the lymphocytes, a type of white blood cell essential for the immune system with various subtypes, including benign hyperplasia, low-grade B-cell, high-grade B- and T-cell, low-grade T-cell, and centroblastic large B-cell lymphoma (Castiglioni V., et al., 2024; Valli, V., et al., 2013). When these cells go rogue, they multiply uncontrollably, affecting the lymph nodes, spleen, liver, and sometimes even the bone marrow. Most dogs with canine lymphoma present with generalized lymphadenopathy (multicentric form) and intermediate to high-grade lymphoma, more commonly of B-cell origin (Valli, V., et al., 2013). But canine lymphoma has its subtypes too.

• Multicentric (systemic) lymphoma: The most common type of canine lymphoma, affecting lymph nodes throughout the body. Symptoms include swollen lymph nodes, increased thirst and urination, loss of appetite, and lethargy.
• Gastrointestinal lymphoma: Also known as alimentary lymphoma, this type of lymphoma affects the stomach and/or intestines.
• Mediastinal lymphoma: A rare form of lymphoma affecting lymphoid organs in the chest, such as the thymus gland or lymph nodes. Symptoms include respiratory distress, exercise intolerance, polydipsia and polyuria (PU/PD) from hypercalcemia.
• Extranodal lymphoma: A rare type of lymphoma that targets a specific organ outside of the lymphatic system, such as the skin, eyes, kidney, lung, or nervous system. Signs depend on the organ involved.

While some dogs show no symptoms early on, others experience swelling in their lymph nodes, lethargy, weight loss, fever, and other signs that something’s up. Catching symptoms early on leads to better treatment options and outcomes.

Traditional Treatment for Canine Lymphoma

Traditional treatment for canine lymphoma typically involves multi-agent chemotherapy protocols such as CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisolone), with some studies exploring modifications like LOPP and LHOP to improve outcomes. Chemotherapy often tops the list, as it effectively reduces tumor size and sends lymphoma into remission. Radiation, too, has its place in localized cases. But while these treatments are effective, they often come with side effects like nausea, vomiting, appetite loss, fatigue, and immune suppression. Not to mention, chemo for dogs is tough—especially for older dogs or those with other health issues.

CBD Oil: A Natural Alternative for Dogs with Cancer

Now, why all the buzz about CBD? Well, CBD (cannabidiol) is a non-psychoactive compound found in cannabis that’s been showing promise as a supportive therapy for dogs with lymphoma. Unlike THC, CBD does not leave a pup feeling “high” but rather interacts with the endocannabinoid system (ECS)—a natural regulatory system in all mammals that controls things like pain, appetite, and immune response. For dogs fighting lymphoma, CBD’s ability to potentially modulate inflammation, ease pain, and even reduce nausea is a game-changer.

How the ECS and CBD Interact to Support Dogs

The ECS is like a control center with two main types of receptors—CB1 receptors in the brain and CB2 receptors in the immune system. When CBD enters the body, it interacts with both, potentially reducing pain, calming inflammation, and enhancing immune responses. A study in Cancer Research concluded that “Cannabinoids show anti-proliferative and apoptotic effects on canine lymphoma cells, suggesting potential as a potential anti-cancer agent for both canine and human B cell lymphoma,” (Omer, S., et al., 2020). This is huge for dogs with lymphoma, as it targets many of the discomforts and symptoms of the disease and its treatment.

6 Potential Benefits of CBD Oil for Dogs with Lymphoma

While research on CBD for lymphoma in dogs is still emerging, several promising effects are making CBD a worthy addition to a pet’s care routine.

1. Pain Management

Cancer and its treatments are painful. CBD’s interaction with interacting with CB1, CB2, 5HT, and TRPV1 receptors has been shown to decrease pain signals and reduce inflammation (Henderson-Redmond, A., Lulek, C., & Morgan, D., 2022), potentially providing relief for pups who are feeling sore or achy. Imagine if a dog moves a little easier, rest a little better, and enjoy the day more comfortably.

2. Easing Nausea and Boosting Appetite

Many dogs undergoing chemotherapy lose their appetite, often due to nausea. CBD has shown a potential to ease nausea possibly by indirectly activating somatodendritic 5HT1A receptors in the dorsal raphe nucleus (Parker, L., Rock, E., & Limebeer, C., 2011). There’s even some research indicating that CBDA (the unheated form of CBD) is even more effective for nausea (Rock, E., et al., 2021). Stimulating appetite in this way helps dogs maintain their weight and energy, supporting their strength in the cancer battle.

3. Reducing Inflammation

Inflammation is a tricky player in lymphoma. While it’s a normal immune response, chronic inflammation worsens cancer symptoms. CBD is known for its anti-inflammatory properties by modulating cytokine production, increasing intracellular calcium levels, activating TRPA1 and mitochondrial targets, inhibiting NADPH oxidase-mediated ROS production, and interacting with CB2 receptors (Henshaw, F., et al., 2021; Lowin, T., et al., 2020; dos-Santos-Pereira, M., et al., 2020; Verrico, C., et al., 2020). It helps reduce swelling and pain, giving dogs a more comfortable experience. By reducing inflammation, CBD even slows the progression of the disease, allowing dogs to stay active and engaged.

4. Immune System Support

The ECS doesn’t just help control pain and inflammation—it also plays a role in immune function through direct suppression of immune cell activation, induction of apoptosis, and promotion of regulatory cells (Nichols, J., & Kaplan, B., 2020). Research is ongoing, but CBD has shown a potential to boost immune responses, which helps dogs with lymphoma better resist infections and stay resilient during treatment. A stronger immune system also helps balance immune responses and prevent the autoimmune reactions that make cancer symptoms worse.

5. Possible Anti-Tumor Properties

Here’s where things get interesting: some studies suggest CBD has anti-tumor effects, like inhibiting cancer cell growth (Heider, C., et al., 2022). Listed below are possible ways on how CBD helps.

• Induce apoptosis: A fancy word for triggering cancer cells to “self-destruct.”
• Inhibit angiogenesis: Preventing tumors from building new blood vessels to supply themselves with nutrients.
• Prevent metastasis: Helping to contain cancer, reducing the spread to other organs. Though more research is needed, the idea of CBD as an anti-tumor agent holds promising potential.

6. Improving Overall Quality of Life

Even if CBD doesn’t cure lymphoma, it makes the journey easier for dogs and their humans. By reducing pain, nausea, and inflammation, CBD helps dogs regain energy, enjoy meals, and stay comfortable. A dog that feels better gets to spend more time being, well, a dog! It’s about quality of life, which is always a top priority for pet owners.

Finding the Right CBD Oil for A Dog’s Cancer Care

Choosing the right CBD oil for a pup makes a huge difference. Listed below is what to look for to ensure consumers are getting the safest and most effective product.

Full-Spectrum CBD: Full-spectrum CBD oil includes all the helpful compounds found in hemp, from cannabinoids to terpenes and flavonoids. This creates what’s known as the “entourage effect,” where the compounds work together to maximize CBD’s therapeutic benefits.

Third-Party Testing: Any reputable CBD brand has its products tested by an independent lab, and those results are easily accessible. This ensures the oil’s potency and purity, confirming it’s free from pesticides, heavy metals, and other contaminants.

Organic and Non-GMO: Choose CBD from organically grown hemp for the purest product. Organic options mean no synthetic pesticides or herbicides, which is crucial when dealing with cancer care.

Dosing and Administration: How Much CBD Oil Does A Dog Take?

While there’s no one-size-fits-all answer, a common approach is to start low and go slow. Begin with a small dose and gradually increase it based on the dog’s size, symptoms, and tolerance. Working with a veterinarian is key here, especially since CBD interacts with some medications. Once the right dose is determined, monitor how a dog responds and adjust as needed.

Listed below are ways to give CBD oil to dogs.

• Directly into the mouth: This is often the most effective, as the CBD enters the bloodstream quickly.
• Mixed with food: Works well if a dog is fussy about taking CBD oil directly.
• CBD-infused treats: A tasty and convenient option, though make sure the treats have the correct dosage and quality ingredients.

Every dog’s reaction to CBD is unique, so observe the pet’s response closely to see what works best.
