Top 5 Best CBD Oil For Dogs With Cancer -Cannabis Effective & Safe 2020

There is a reason they say dogs are a man’s best friend. Our dogs are more than just pets – they’re members of the family. This is why it’s particularly devastating when they get sick. Keeping up with routine veterinary care and providing a nutritious diet are two of the most important ways to support your dog’s health. However, dogs can get sick even when they have the very best of care. 

In an English study on the prevalence of health disorders in dogs, 75.8% of canine participants [1] were diagnosed with at least one disorder during the study period. The conditions a dog is likely to develop over the course of its lifetime vary according to numerous factors such as breed, diet, and activity level. While some dogs are lucky enough to live long and healthy lives, the American Veterinary Medical Association (AVMA) reports that almost half of dogs over the age of 10 will develop cancer. 

In this article, we’ll talk about the types of cancer seen in dogs and how CBD oil might be helpful in managing the condition. You’ll also see our top picks for the best dog CBD products.

Hemp Oil for Dogs

Cancer treatment for dogs [2] can be difficult. Surgical removal of tumors is typically the first step, followed by chemotherapy and/or radiation. Even if these treatments are effective, they often come with side effects of their own. Loss of appetite, lethargy, diarrhea, and vomiting are fairly common side effects and some dogs experience lingering pain. 

Recent studies suggest that CBD oil may help improve quality of life [3] for dogs undergoing cancer treatment. Though the effects of CBD for dogs are less well studied than the effects on humans, small studies and anecdotal reports offer promising results. 

When it comes to CBD for dogs, there are many products to choose from. Dog CBD products are not all created equal, however, and it’s your job as a pet owner to shop smart. Read on to learn what to look for and to see our top 5 picks for CBD oil products for dogs.

Spruce CBD uses only 100% natural, lab-grade full-spectrum CBD. Their products are lab-tested for safety and quality, and they are made in the USA. This brand is free from pesticides and low in THC, tested under 0.3% THC.

Cannabis Oil for Dogs with Cancer 

Cancer accounts for roughly half the deaths [6] of dogs over 10 years of age. Though the cause of cancer is still being studied, new treatment methods are constantly under development and knowledge about the disease continues to grow. Different types of cancer manifest in unique ways, but many of the early signs tend to overlap.

Here are some of the most common signs of cancer in dogs:

  • Sores that fail to heal properly
  • Abnormally swelling
  • Loss of interest in food
  • Unexplained weight loss
  • Difficulty eating or swallowing
  • Hesitation to exercise
  • Difficulty breathing or urinating

Confirming a cancer diagnosis requires more than an observation of symptoms. Your veterinarian will need to perform additional tests to rule out other potential conditions and may perform blood work, urinalysis, and biopsies to confirm a cancer diagnosis. Once the diagnosis is confirmed, you can begin discussing treatment options. While talking to your vet about the options for treatment, you may want to ask about CBD for dogs.

What is CBD Oil? 

Though you may be familiar with cannabis in the form of marijuana, this isn’t something you should offer your dog. Marijuana contains high concentrations of tetrahydrocannabinol (THC), a psychoactive compound which can be very dangerous for pets [7]. One of the other active ingredients in cannabis, cannabidiol (CBD), however, can actually be very beneficial.

Cannabidiol or CBD is not a psychoactive compound, so it doesn’t produce a “high” like THC. CBD has been used as a therapy for a variety of conditions [8] including pain management, anxiety relief, arthritis pain, and even seizures. Though the use of CBD for treating these conditions is still under-researched, there are small studies and anecdotal evidence to support each. 

How Does CBD Oil Work? 

The mechanisms through which CBD helps reduce inflammation and relieve pain are not fully understood. Scientific research regarding the use of pet CBD is limited, but certain hypotheses can be made from its effects in humans and other animals. Given existing research about the effects of CBD in people, veterinarians believe the benefits of CBD for dogs may be linked to its effects on the endocannabinoid system or ECS. 

The endocannabinoid system is present in all members of Animalia, including both humans and dogs. It is a complex cell-signaling system that helps maintain homeostasis [9] in the body by regulating important bodily functions including appetite, mood, memory, and sleep. 

The ECS contains two types of cannabinoid receptors: CB1 and CB2. Though these receptors are designed to interact with endocannabinoids (natural cannabinoids produced in the brain), they have been shown to interact with plant-derived endocannabinoids like CBD as well. The effects of CBD on the endocannabinoid system are vast and varied, but many are beneficial.  

What Benefits Does it Provide for Dogs with Cancer? 

Before giving your dog CBD oil, it’s important to understand that CBD alone has not been shown to be an effective treatment for cancer. Pet CBD is primarily used as a supportive therapy to promote general wellness and relief from symptoms. That being said, it could be a beneficial addition to your dog’s cancer treatment plan.

Here are some of the potential benefits of CBD oil [10]:

  • Reducing inflammation
  • Appetite stimulation 
  • Relieving or reducing pain
  • Anxiety and depression relief
  • Relief from nausea 
  • Slowed tumor growth

Cancer is a difficult disease to treat because it is not fully understood and because it can change and spread rapidly. One of the biggest potential benefits of CBD for dogs is related to its ability to slow the proliferation of cancer [11] cells. Though canine studies are limited, mouse studies [12] revealed that CBD combined with chemotherapy tripled survival rates in mice with pancreatic cancer. At the very least, many dog owners report improved quality of life in aspects of pain management, appetite stimulation, and relief from cancer treatment side effects. 

How Safe is Hemp Oil for Dogs with Cancer? 

Before giving your dog anything – whether food, medication, or supplement, it’s important to understand what it is and how it works. Never give your dog anything new without your veterinarian’s approval. Even natural supplements can interact poorly with certain medications, and you want to make sure anything you give your dog is safe. 

When used properly, CBD is generally regarded as safe by respected organizations including the World Health Organization (WHO). Keep in mind that the majority of studies regarding CBD use are human trials, however, so it’s important to follow your veterinarian’s advice and to use your best judgment when choosing CBD products. 

When shopping for CBD oil, look for products made with high quality, full-spectrum CBD [13]. Avoid products that contain chemical additives and make sure the product has been tested by a third party for safety and quality. Pet owners should keep in mind that different CBD products come in various concentrations, so you’ll need to follow the dosing instructions for the specific product.

How Much CBD Oil Should I Give My Dog for Cancer? 

Because using CBD for pets is still fairly unstudied, there is no standard dosage recommendation. When using CBD, pet owners should follow the dosing information on the product according to their dog’s body weight. 

Keep in mind that smaller doses are usually effective for general wellness and anxiety relief, but higher doses may be required for the treatment of more serious health problems such as cancer. Start with the lowest recommended dosage to see how your dog reacts and increase the dosage if needed. Talk to your veterinarian to make sure your dog’s current medications won’t be affected. 

Though CBD oil may not be a miracle cure for cancer, it could very well help relieve some of your dog’s pain and improve its quality of life. Just be sure to read the information on the label carefully and monitor your furry friend for side effects.
