Nothing is more heartbreaking than losing a pet. For many dog owners, however, it isn’t a sudden loss but a slow decline which can be even more difficult to bear.

Though many dogs live long and healthy lives, the truth is our canine companions simply don’t live as long as we do. The leading cause of death in dogs over the age of 10 is cancer. That being said, half of all canine cancers are curable if caught early enough. But what do you do if you find out your dog has it?

The first step in treating your dog’s cancer is getting an accurate diagnosis to identify the type of cancer and its severity. From there, you and your veterinarian can discuss treatment options. In many cases, dogs require a combination of surgery and chemotherapy or radiation. Immunotherapy (which includes cancer vaccines) may be recommended as well.

If you know anything about cancer treatments in humans, you know they can be pretty brutal. Fortunately, dogs tend to tolerate treatments like chemotherapy better than humans. Even so, you may be considering alternative options or therapies to support your dog’s health during treatment.

Many pet owners are turning to CBD oil as a natural treatment for all kinds of canine health problems, including cancer. Read on to learn the basics about CBD oil for dogs and to learn about the best CBD oil for dogs with cancer.

CBD Oil for Dogs with Cancer

Roughly 1 out of 4 dogs develop some form of cancer during their lifetime. The most common forms of cancer in dogs are lymphoma, melanoma, and mammary cancer. Though the exact cause for cancer remains a mystery, many cases can be traced to the site of earlier wounds, fractures, or other injuries. In other cases, genetics seem to play a factor, as some breeds are more prone to certain types of cancer.

When it comes to treating cancer, it’s important to follow your veterinarian’s advice. You are the best advocate for your dog’s health and wellness, however, so speak up if you have questions!

If you’re worried about the side effects of chemotherapy or you’re wondering whether there might be a natural alternative to help manage your dog’s symptoms, don’t be afraid to ask. Many pet owners are using CBD oil to support their dogs’ health and there is some evidence to suggest that it may even be beneficial for dogs with cancer.

What is CBD Oil?

Before giving your dog a new medication or supplement, it’s important to do your research. Not only do you need to know that the product is effective, but you should know whether it’s safe. You may be familiar with CBD and other cannabis products for human use, but are they safe for dogs?

Cannabidiol (CBD) is simply a phytochemical found in Cannabis. A phytochemical is just a naturally occurring compound derived from plants – CBD is one of over 100 cannabinoid compounds that have been isolated from the Cannabis plant. Cannabis is the same plant from which tetrahydrocannabinol (THC) is derived, but CBD doesn’t have the psychoactive properties of THC – it won’t get your dog high. Instead, it provides therapeutic benefits such as relieving pain and anxiety, reducing inflammation, and it may even slow the spread of cancer.

When it comes to utilizing the benefits of CBD, most products are made with CBD oil which has been extracted from hemp, Cannabis sativa. Hemp seed oil is very rich in cannabinoids, but CBD is the active ingredient – it contains very little THC. It is also rich in omega fatty acids and essential nutrients.

Does CBD Oil Work for Dogs with Cancer?

Cannabis has a long history of therapeutic use in humans but because it has long been a controlled substance, scientific research is limited. In 2018, FDA regulations changed to make CBD products legal as long as they contain less than 0.3% THC by dry weight. Today, you can find all kinds of CBD products for dogs including oil tinctures, CBD-infused treats, balms, and more.

The big question is: does CBD work for dogs with cancer?

What you need to remember is that research regarding the effects of CBD in humans is limited, but research in dogs is even more limited. There are, however, several studies that support the anti-cancer effects of CBD in humans which means there is some potential for a similar effect in dogs.

Here’s a quick overview of a few studies regarding CBD for cancer:

  • In a 2018 mouse study, CBD treatment combined with chemotherapy tripled survival rates for mice with pancreatic cancer.
  • A 2018 study supports the anti-tumor benefits of CBD treatment. It was shown to induce apoptosis (cell death) and inhibit tumor cell growth and metastasis.
  • A 2017 study showed the benefits of medical cannabis and CBD for the management of cancer-related pain.

The jury is still out on whether CBD is an effective form of treatment for canine cancer, but the research is promising. Even if CBD doesn’t cure your dog’s cancer, it could provide other supportive benefits. Many dogs with cancer suffer from pain, anxiety, and inflammation – all of these are conditions which can be mediated by CBD. Talk to your vet about adding CBD oil to your dog’s treatment plan.

How to Shop for CBD Oil

Your dog’s health and wellness are your responsibility, so it’s important to do your research before giving him anything new. CBD oil is generally recognized as safe, but there is still a lot we don’t know about it and the quality can vary greatly from one product to another.

Here are some things to look for when shopping for CBD:

  • Make sure the company discloses where their CBD oil comes from – many dog owners prefer products that contain USA-grown hemp oil.
  • Check for the concentration of CBD in the product and look for a Certificate of Analysis (COA) from a third-party lab to verity the potency.
  • Look for other ingredients in the product – regular CBD oil may include a carrier oil but shouldn’t contain artificial additives.
  • Know the difference between broad-spectrum and full-spectrum CBD oil – broad-spectrum oil has had the THC removed while full-spectrum may contain up to 0.3% THC by dry weight.
  • Compare prices by calculating the price per mg of CBD – this is the best way to tell whether you’re getting a better deal on a similar product.

In addition to taking the time to shop smart for CBD oil for dogs, you also need to make sure you’re dosing it properly. There is no standard dosage for CBD in humans or dogs, so you’ll probably need to do a little tinkering to find the right dose. Ask your vet for recommendations and follow the instructions on the label for the product you’ve chosen.
