• Cancer in dogs may manifest in symptoms such as non-healing wounds, lumps, inflammation, and irregular bleeding(1).
  • CBD, also called cannabidiol, is a cannabinoid found in cannabis. The compound may possess anti-pain and anti-inflammatory effects(2). These benefits may help with symptoms of dog cancer.
  • A 2016 review of study results conducted in preclinical animal models suggested that cannabinoids may reduce cancer cell growth and proliferation and may contain anti-cancer effects(3).
  • CBD’s therapeutic potential may be promising. However, pet owners should first consult a veterinarian regarding the dogs’ medical condition for appropriate treatment options to improve their dogs’ quality of life(4).

    Spruce’s dog-friendly CBD has been specially formulated for dogs. Instead of hemp seed oil for the carrier oil, the product contains coconut oil, which is generally easier on the digestion for dogs. The taste is also milder with no flavorings, making it more likely that dogs will eat it with their food.

    Using Spruce CBD for dogs is simple. All owners have to do is sprinkle the desired dose on the dog’s food at mealtime once or twice a day. Each dose should consist of about two to three drops per 20 pounds of dog weight.

How CBD Oil May Help Dogs With Cancer

The FDA (Food and Drug Administration) stated that canines may get cancer at a similar rate as humans(5). Moreover, the treatments available to manage cancer in animals are also approved for people. 

Canine cancer signs may include a wound that does not heal, lumps, inflammation, and abnormal bleeding(6). 

CBD, more popularly known as cannabidiol, is one of the cannabinoids found in cannabis plants. This compound has gathered therapeutic interest in veterinary medicine(7) and may also contain analgesic (anti-pain) and anti-inflammatory properties(8). 

The compound’s therapeutic properties are induced due to CBD’s interaction with the canine’s endocannabinoid system (ECS) and its cannabinoid receptors CB1 and CB2. These receptors can be found in the nervous and immune systems(9).

According to a study in 2016, cannabinoids may play a role in decreasing tumor growth and proliferation. The research hypothesized that cannabinoids may contain anti-cancer effects(10).

Moreover, according to an article published in the Journal of Pharmacology and Experimental Therapeutics, CBD may cause apoptosis or cell death in cancer cells through direct or indirect activation of the CB2 receptors(11). 

The clinical research results also hypothesized that CBD may inhibit the growth of cancer cells. 

Despite the promising therapeutic potential of CBD, the FDA does not approve the use of cannabis and any form of cannabis derivatives on animals. The agency suggests consulting a veterinarian for an official diagnosis and suitable treatment options(12).

Additionally, some veterinarians in the United States of America (USA) may not be legally allowed to discuss, dispense, or recommend CBD products to their clients. However, pet owners may still initiate an open conversation with these professionals(13). 

Can CBD Oil Help Dogs With Cancer?

The American Kennel Club (AKC) states that CBD has purported medical benefits such as anti-inflammatory, anti-nausea, anti-anxiety, appetite-stimulation, and anti-cancer benefits(14).

These effects of cannabidiol may help manage symptoms of canine cancer. 

What Are the Benefits of CBD Oil for Dogs With Cancer?

Some signs of cancer in dogs include pain, abdominal swelling or inflammation, bumps, and non-healing sores(15). 

CBD may contain therapeutic benefits that may help manage symptoms of canine cancer.  

Research on CBD Oil for Dogs With Cancer

There is a lack of scientific research on the benefits of CBD oil for dogs with medical illnesses like cancer. However, anecdotal evidence suggests that the compound may deliver pain relief(16). 

These accounts indicate that CBD may be promising for pain management. 

According to a survey report from the Journal of the American Holistic Veterinary Medical Association, approximately 77.6% of dog owners stated that they use hemp-derived products for their pets’ medical illnesses, which were diagnosed by a veterinarian(17). 

The report indicated that the most common canine conditions are seizures, arthritis, anxiety, and cancer.  

 A recent study hypothesized that CBD may effectively hinder cell-reproduction and induction of autophagy and apoptosis across abnormal cell lines(18).

Autophagy refers to the body’s ability to remove damaged cells. Meanwhile, apoptosis refers to the elimination of potentially harmful cells and terminates immune responses(19). 

Research in 2020 discussed that CBD may possess therapeutic potential in managing cancer and cardiovascular, metabolic, and neurodegenerative diseases(20). 

CBD’s purported benefits may be promising. However, these clinical studies are not specific to canines. Further research is necessary to determine the therapeutic effects of CBD on dogs with cancer. 

How Is CBD Administered?

Dog owners may utilize various methods of administering high-quality CBD oil and other CBD-derived products to dogs with cancer. 

CBD tinctures are administered under the dogs’ tongue or mouth, allowing the compound to enter the mucous membranes and bloodstream(21).

CBD oil tinctures are made by infusing CBD extracts with carrier oils like MCT oil, coconut oil, and hempseed oil.

This form also comes with a dropper, which allows pet parents to administer CBD to their dogs accurately. 

If a canine dislikes the natural flavor of cannabidiol, pet owners can add CBD oil to dog treats or mix it into the dogs’ food.

Meanwhile, CBD dog treats are an easy way to feed canines the compound. Treats and chews usually come in flavors like peanut butter and bacon that appeal to dogs. 

Lastly, individuals can give their pet CBD oil by directly applying the compound to the animal’s skin. CBD topical products may come in creams and salves and be used for localized pain relief. 

Choosing the Best CBD Oil

When choosing the best CBD oil for dogs with cancer, pet owners should consider the following pertinent information: 

  • In looking for different hemp extracts, the AKC recommends broad-spectrum CBD oil over full-spectrum hemp oil(22). 

This recommendation is due to full-spectrum CBD oil’s THC (tetrahydrocannabinol) content, which may cause toxicity in dogs(23).

THC is the principal psychoactive compound of cannabis.

  • It is vital to check the quality of CBD oil and whether the compound contains additives like GMOs (genetically modified organisms) or pesticides, which can be harmful to canines.  

CBD Oil Dosage for Dogs With Cancer

The FDA has not approved CBD usage to treat any veterinary medical issue(24). Thus, there is no set CBD dosage for dogs with cancer.

However, a 2018 study indicated that 2mg of CBD oil per kilogram of a dog’s body weight given twice daily may increase osteoarthritic dogs’ comfort and activity(25). 

Osteoarthritis is a chronic disease that causes joint pain(26).

Moreover, a recent study suggested that a range of 2.5 micrograms per milliliter of CBD may reduce the canine cancer cell reproduction of five canine neoplastic cell lines(27). 

Still, these clinical trials are inconclusive. Hence, dog owners should still consult a veterinarian who is an expert in cannabis use. 

However, it is vital to note that the state veterinary medical board mandates to what extent veterinarians are allowed to guide their clients in terms of CBD product usage(28). Thus, pet owners may encounter limitations. 

Are There Any Risks of Using CBD Oil for Dogs With Cancer?

There are no scientific studies on CBD’s potential risk and side effects on dogs with cancer. 

However, in general, dogs that are given CBD may experience side effects such as(29):

  • Appetite loss
  • Vomiting
  • Diarrhea
  • Lethargy

Do Veterinarians Recommend CBD for Cancer in Dogs?

Under current federal and state laws, veterinarians are prohibited from recommending, prescribing, administering, or dispensing cannabis or any cannabis-derived products to animals(30).

However, Nevada veterinarians may suggest and administer CBD products that contain less than 0.3% THC concentration(31).

Nonetheless, pet owners should be comfortable initiating a discussion about CBD oil with their veterinarians. 

How CBD Compares to Alternative Dog Cancer Treatments

The Budwig diet, consisting of flaxseed oil mixed with milk and cheese, was developed by a German biochemist as a possible way to inhibit the growth of cancers(32). 

Animal studies have shown that flaxseed may help with cancer by shrinking or reducing the growth of tumors(33). 

Thus, some pet owners may consider flaxseed oil as an alternative and natural treatment for cancer in their dogs. 

However, further studies are needed regarding the topic of flaxseed oil and dog cancer as there is no substantial evidence that supports flaxseed’s efficacy against the medical condition. 

On the other hand, CBD oil has purported anti-cancer therapeutic benefits(34). These effects may help manage canine cancer. 

Still, pet owners are advised to consult with a veterinarian before trying CBD as an alternative treatment for their dogs with cancer.

What Is CBD Oil?

Cannabidiol is a principal compound of Cannabis sativa L. or hemp plants. 

The most common CBD format is CBD oil. However, the compound may also come as extracts, oil-based capsules, and CBD-infused food and drinks(35).

Canine Cancer Overview

How Common Is Cancer in Dogs?

According to the American Veterinary Medical Association (AVMA), dogs over 10 years old are more likely to develop cancer. Moreover, canine cancer rates are roughly similar to humans(36). 

In addition, types of cancers like lymphoma are more prevalent in cats than dogs(37).

Dog Cancer: Signs and Symptoms

Cancer is characterized by the rampant growth of abnormal cells. However, cancer symptoms may differ depending on the type and location. Some signs of the canine disease are(38):

  • Unusual swelling, bumps, or lumps that grow larger 
  • Difficult to heal sores or wounds
  • Weight loss and loss of appetite
  • Unpleasant odors 
  • Discharge in the mouth, nostrils, or anus
  • Lethargy 
  • Joint stiffness
  • Issues with breathing and expelling waste 

Diagnosing and Treating Dogs With Cancer

Pet owners may find tumors in their dogs while bathing or petting the animals. If an individual feels any abnormal growths on their pet’s body, it is vital to set an appointment with their veterinarian(39). 

For a more accurate diagnosis, veterinarians may get cell samples from the growths to determine what type of tumor it is or palpate (feel through touch) the dog’s body during the medical examination(40).

Early diagnosis and treatment of canine cancer are key to successful pet recovery. Cancer treatments for dogs are similar to humans’, such as(41): 

  • Chemotherapy
  • Radiation therapy
  • Surgery
  • Holistic or herbal therapy

However, in instances where the dog is not responding to treatments like chemotherapy, euthanasia, or a painless, medically induced death, it is an option to prevent the animal from suffering(42). 

It is vital to note that this method may create ethical issues for the veterinarian. 

Currently, there are no studies on whether CBD may be applicable for use in terminally ill or dying dogs. 

Therefore, while pet owners may consider giving CBD to their dying dogs, there is no certainty regarding the compound’s effects on the pet.

Types of Cancer in Dogs

The most typical types of cancer in dogs are(43): 

  • Lymphoma: This type of cancer appears as swollen lymph nodes or glands around the neck, shoulders, or knee. Poodles, golden retrievers, and Australian shepherds are some breeds with a higher risk of lymphoma.
  • Hemangiosarcoma: This cancer appears as a tumor within the lining of the blood vessels and occurs mostly in middle-aged or older dogs. The common symptom of hemangiosarcoma is an enlarged spleen. 
  • Osteosarcoma: Bone cancer in dogs primarily affects giant dog breeds or older canines. Osteosarcoma occurs in the bones around the legs or shoulders and may induce lameness, pain, and swelling in the affected area. 
  • Melanoma: Dogs with dark skin are more at risk of developing this form of cancer. Melanomas occur from pigment-producing cells (melanocytes), which cause the coloring of the skin. Melanomas appear like small, dark lumps or large, flat masses around the dog’s mouth or toenail beds. 

FAQs

1. Is CBD legal for dogs?

Many states in the United States of America have passed laws allowing the use of marijuana under strict policies(44). However, these state laws legalizing CBD use in humans do not apply to animals(45).

Moreover, regulations on CBD and medical marijuana usage may vary depending on the state. Thus, dog owners should verify state laws if they plan on giving CBD to their pets. 

2. What effects does CBD have on a dog?

The book Healing With CBD stated that CBD may have therapeutic effects on dogs and cats(46). The resource also indicated that these animals are more sensitive to THC.

The ingestion of the psychoactive compound in large doses may cause toxicity(47).

This occurrence is due to dogs having more cannabinoid receptors in their brains than humans(48).

3. Does CBD have any negative side effects in dogs?

Dogs taking CBD may experience loss of appetite, diarrhea, vomiting, or lethargy. If the compound is taken in large doses, canines may also experience ataxia or uncoordinated movements(49).

4. Are there different kinds of CBD products that may be prescribed for dogs?

CBD may come in different forms that pet owners may give to their dogs suffering from cancer. Such products include CBD dog treats, CBD tinctures, and topicals like CBD creams and salves.
