Benefits of CBD Oil For Dogs With Cancer

To understand the benefits of CBD Oil for dogs with cancer, it’s important to first understand a process known as apoptosis, or natural cell death. Apoptosis is a completely natural process wherein cells that are damaged, or no longer useful, die . Cancer cells do not die on their own ; they do not undergo apoptosis. Which is why they are able to continuously spread unless we do something to stop them.

That’s why the endocannabinoid system is so critical in the body. Every mammal has an endocannabinoid system ; us, your dog, your cat, even lions and tigers and bears, oh my. The endocannabinoid system’s purpose is to bring the body back to balance .

As cancer progresses, cancer cells reproduce faster than the endocannabinoid system can handle. It’s no longer able to bring the body back to balance without some type of assistance. The cancer cells begin to spread throughout the body at that point; a process known as metastasis. So what does that have to do with CBD for dogs with cancer? Let’s get into the research.

Research on CBD For Dogs With Cancer

In a recent study, researchers conducted a study to determine how effective cannabis is against canine cancer cells. The study compared CBD for dogs with cancer to a combination of common chemotherapy pharmaceuticals. The study showed CBD for dogs with cancer to be effective at hindering cell proliferation and induction of autophagy and apoptosis rapidly across neoplastic cell lines.

In another promising study conducted in Canada, research was conducted to investigate CBD’s abilities against canine urothelial carcinoma (bladder cancer). The study analyzed the difference in efficacy between the traditional standalone treatment, chemotherapy, versus chemotherapy and CBD for dogs with cancer. The results showed that CBD for bladder cancer not only reduced cell viability and induced cell death in the canine urothelial cells on its own, but worked even better when combined with chemotherapy.

This study was done in vitro, which means it was done outside of a living organism. Further studies in vivo (within a living organism) are warranted, so that we can investigate how exactly this combination will be most successfully implemented in a clinical setting, and also to be able to transfer this into the human clinical setting. However, due to the nature of cannabis, in terms of its continued vilification by governments domestically and across the globe, researchers are limited in their scope. Until cannabis is de/rescheduled on the federal level, research cannot be done on living organisms (such as clinical trials on people). For now, as much preclinical work is being done as possible to create the foundation for clinical research when cannabis is descheduled federally.

The extent of the research being done on cannabis’ effect on cancer cells is only growing, and new research showing the benefits of CBD for dogs with cancer continues to emerge. As time goes on, and the demonization of cannabis lessens, more research is done proving cannabis (CBD, CBN, THC, and its other compounds) has a huge effect on cancer cells, and improving existing cancer treatments. We already know that CBD triggers apoptosis, stops metastasis, and has a positive effect when used with chemotherapy, but new research is constantly emerging regarding specific cancers and cannabis therapy.

According to research, CBD for dogs with cancer has been shown to:

  • Inhibit tumor growth (via apoptosis)
  • Trigger death of cancer cells (via apoptosis)
  • Inhibit the formation of blood vessels that feed tumors (angiogenesis)
  • Discourage the spread of cancer from one part of the body to another (metastasis)

Most importantly, it helps with your pet’s quality of life!

Dosing CBD Oil For Dogs With Cancer

The first thing to do is spend some time determining the dosage that will be most effective for your pet. Despite common misconceptions, dosing CBD for dogs with cancer has very little to do with your dog’s size and weight. Dosage is most effectively determined with consideration for each animal’s unique physiological condition. This includes characteristics such as their endocannabinoid system, age, metabolism, disease process, current ailments and other individual health factors.

During the first few weeks, we recommend a trial and error method as you monitor your animal’s response and determine optimal dose. The old saying “start low and go slow” is extremely applicable when considering Full Spectrum Hemp Extract for your animal.

Hemp extract is extremely safe, even at high levels . The most common, however unlikely, side effects you may see are sleepiness or loose stools/diarrhea.

For the fastest and most thorough absorption of CBD oil for dogs with cancer, lift the lip and apply dose directly onto the gums. If added to food, the dosage may not be as effective and can take significantly longer (30-45 min.) to reach the bloodstream as it works its way through the gastrointestinal system.

Split the recommended daily dosage into smaller doses throughout the day (micro-dosing) for best absorption and to keep it in the bloodstream. The cannabinoid concentration peaks at 2 hours and is gone from 4-6 hours. Make sure to shake the bottle before each use and always keep away from heat.

Vets Using CBD Oil For Dogs With Cancer

Of course, many reputable veterinarians also trust CBD for dogs with cancer, and have their own evidence to prove that it works. Because of this, I asked Dr. Trina Hazzah, DVM, DACVIM, CVCH, if she uses CBD on her own patients. Dr. Hazzah is a veterinary oncologist at VCA Animal Hospital in Las Vegas (one of the largest and most respected veterinary hospitals in the world).

The short answer: Dr. Hazzah has used cannabis with her patients and has seen great success.

CBD Success Story: Hammer

“Years and years ago, there was a little dog named Hammer,” says Dr. Hazzah. “He was a Jack Russell, and the owners came in and the dog had three cancers at the same time. He had low-grade lymphoma, bladder cancer, and an oral squamous cell carcinoma.”

Dr. Hazzah discussed all of the options with Hammer’s parents, and they decided the quality of life was most important. They focused on targeted therapy, which was effective for about six months until it seemed to stop working as effectively.

“Around the five or six-month mark, the oral cancer started to get so large that it took up his entire face,” says Dr. Hazzah. “The bladder cancer was getting worse, lymphoma was static. The owners went over the options again, and one of the things we discussed was cannabis. As an integrative oncologist, I felt that I should guide them through the process to make sure it was safe. The dog had 1 mg of THC and 1 mg of CBD, twice a day, along with targeted therapy.”

Within two to three weeks, Hammer’s owner said his eye was starting to open a little bit more. A month after starting the cannabis regimen, Hammer came in and Dr. Hazzah could not find the oral tumor at all.

“Not only could he open his eye, but when he opened his mouth, I just saw a little redness,” says Dr. Hazzah. “The tumor was not there. Hammer was happy, and this was just 1 mg. This goes back to my theory that it wasn’t the amount, it was what the cancer needed.”

CBD Success Story: Nina

It’s been eight months and my 8-year-old, Nina is thriving on a strict regimen including a Full Spectrum Hemp Extract, a Full Cannabis extract with high THC, mushrooms , and diet. She’s already breaking records, and because of this, I want to share what I did with you.

10 Best CBD Oils for Dogs with Cancer in 2022 – Reviews & Top Picks

Your furry friend is an integral part of your family, and it’s heartbreaking to watch your pet suffer from cancer. Chemotherapy and other cancer treatments can cause side effects in dogs just as they do with humans. If the effects of the disease and treatments are difficult for your dog to handle, you can use CBD products to relieve symptoms and make your pet more comfortable.

Although CBD has shown promise with anecdotal evidence from dog owners, the FDA has not approved it as a treatment for humans or dogs. Before administering CBD drops to your dog, talk to your veterinarian for dosage advice and treatment tips. CBD oil is not available through large retailers like Chewy or Amazon, but we developed a list of the best CBD for dogs and reviews with links to CBD manufacturers.

A Glance at Our Favorites in 2022

The 8 Best CBD Oil for Dogs with Cancer

1. Royal CBD Full-Spectrum Pet Oil – Best Overall

Size 0 ounce
Potency 250 mg, 500 mg

Royal CBD has had success manufacturing CBD products for humans, and their Full Spectrum CBD Pet Oil is our winner for the best overall CBD oil for dogs. Royal CBD only uses organic, non-GMO hemp from California farms. The oil comes in 250-milligram and 500-milligram dosages, and it’s suitable for all breeds and life stages.

We liked Royal CBD’s commitment to quality and transparency with all its products. Each batch of CBD oil is tested by private labs to ensure the liquid is pure and safe for consumption. Compared to similar brands, Royal CBD is more expensive, but you do not have to worry about pesticides or other chemicals contaminating the CBD.

2. CBD Pure CBDPet 100 – Best Value

Size 0 ounce
Potency 100 mg

If you’re hesitant to use a high dosage of premium CBD oil, you can try CBD Pure, which only contains 100 milligrams of CBD per bottle. We could not find another company that made high-quality CBD for such a low price, and CBD Pure won our best CBD oil for the money award. CBD Pure is ideal for owners of small and miniature breeds because of the lower concentration of CBD, and you can increase the dosage at any time. If you order multiple bottles of CBD Pure, you pay even less, but unfortunately, the manufacturer does not offer free shipping.

3. Spruce CBD Dog CBD Oil – Premium Choice

Size 0 ounce
Potency 750 mg

Dogs that have taken CBD before may benefit from a higher dosage, and you can use Spruce CDB for a 750-milligram dosage of CBD. Spruce CBD does not source its hemp from farmers that use pesticides, and each product is tested in a third-party facility. The company manufactures its oil for dogs in the same “human-grade” facility it makes CBD products for humans, but it replaces the hemp seed oil in its other recipes with coconut oil for dogs.

Some dogs dislike the taste of hemp, but most enjoy the flavor of coconut, and the oil is easier to digest than hemp oil. Customers were happy with Spruce CBD, but several were disappointed with the oil’s high price.

4. Honest Paws CBD Oil for Dogs – Best for Puppies

Size 0 ounce
Potency 125 mg, 250 mg, 500 mg, 1,000 mg

Honest Paws uses organic hemp without artificial flavors for its CBD oil for dogs, and it features more dosage options than most producers. If you have a puppy, you can start with a small dose, or you can use a higher dosage for an adult dog. Honest Paws uses non-GMO, organic hemp for its CBD oil and tests its products at private laboratories to ensure safety.

You can adjust the delivery date of your products and set up automatic monthly shipments. Honest Paws offers a 30-day money-back guarantee with all its products, and you can cancel monthly shipments at any time. The 125-milligram bottle is affordable, but there’s a significant price increase when you order higher dosages.

5. Nuleaf Naturals CBD Oil for Dogs

Size 5 ounces
Potency 300 mg, 900 mg, 1,800 mg

Nuleaf Naturals is one of the few producers that has been certified by Good Manufacturing Practices (GMP), and its production facility is certified by the Food and Drug Administration (FDA). Nuleaf makes organic CBD oil for dogs from 100% Colorado-grown hemp, and it offers three dosage levels of CBD: 300 milligrams, 900 milligrams, and 1,800 milligrams.

The oil is free of additives and flavorings, and its only ingredients are organic virgin hemp seed oil and full-spectrum hemp extract. The full-spectrum blend contains CBD and cannabinoids like CBN, CBG, and CBC. Nuleaf Naturals is a high-quality product, but its higher dosages may not be suitable for all dogs. Also, the half-ounce bottle is a little pricey.

6. Joy Organics CBD Oil for Pets

Size 0 ounce
Potency 450 mg, 900 mg

Joy Organic produces several CBD products for humans, and they make 450-milligram and 900-milligram CBD oil for pets. The oil is made with extra virgin olive oil and broad-spectrum hemp extract. You can make one-time purchases from the Joy Organic website or enroll in its subscription program for recurring deliveries. Since the oil is not a full-spectrum formula, it does not contain traces of THC like its competitors.

Customers seem happy with Joy Organics for pets, but the lower dosage may be too large for some dogs, and Joy Organics suggests using the drops for larger breeds. Joy Organics has a rigorous testing program, but it had to recall an orange tincture for humans in 2018.

7. Charlotte’s Web Full Spectrum Hemp Extract

Size 38 ounces
Potency 17 mg

Charlotte’s Web Full Spectrum Hemp Extract is available in unflavored and chicken flavor tinctures. Charlotte’s Web only recently began producing CBD drops for dogs, but it’s committed to ensuring its products are pure and safe. It quality tests its oil 20 times before packaging it for shipping, and it never uses chemicals, pesticides, or GMO ingredients. Charlotte’s Web may be a practical option if you’re hesitant to use higher dosages, but the oil does not contain much CBD. At 17 milligrams per bottle, it has the lowest CBD content on our list, but it’s similar in price to oils with higher CBD amounts.

8. Medterra CBD Pet Oil

Size 5 ounces
Potency 150 mg, 300 mg, 750 mg

Medterra is a new company that recently began making CBD products for pets. Its CBD Pet Oil is an isolated product that does not contain additional cannabinoids like full-spectrum or broad-spectrum formulas. The oil uses organic USA-grown hemp and features unflavored and chicken-flavored versions for picky dogs.

Medterra products are approved by the U.S. Hemp Authority and tested by third-party facilities for quality. Although Medterra seems to produce high-quality CBD oil, the company is relatively new, and we could not place it higher on our list due to the limited evidence of the product’s performance.

9. Gold Bee Full-Spectrum CBD

Size 0 ounce
Potency 600 mg

Gold Bee makes full-spectrum CBD oil for pets with peanut butter flavor. The oil is produced from Colorado-grown hemp, and it’s third-party tested to ensure purity and safety. Gold Bee uses organic MCT oil from coconut in its tincture to provide essential fatty oils to your pet’s diet. Gold Bee is new to the CBD industry and has only made CBD products for around three years.

Customers seem satisfied with the oil, but the 600-milligram dosage may only be appropriate for larger pups. We were concerned that the company did not list its ingredients or mention the composition of the peanut butter flavoring. Since the recipe is not on the company website, we assume the flavoring is artificial.

10. CBDfx CBD Oil for Pets

Size 0 ounce
Potency 250 mg, 500 mg, 1,000 mg, 2,000 mg

CBDfx is primarily focused on CBD products for humans, but it recently added a few products for canines. The CBDfx oil for pets is made with non-GMO, organic hemp and a natural bacon flavoring. Unlike many companies, CBDfx offers 4 CBD strengths: 250 milligrams, 500 milligrams, 1,000 milligrams, and 2,000 milligrams.

The drops are made in the USA and come with a 60-day money-back guarantee. CBDfx is expensive for a broad-spectrum product, and some of the language on the website seems misleading. The CBD oil for pets is a vegan product, and it’s unclear how a “natural” bacon flavor was produced without using a pig.

Buyer’s Guide: How to Choose the Best CBD Oil for Dogs with Cancer

CBD oil may help your canine handle the effects of cancer treatments, but it’s best to check with your veterinarian before administering CBD. Vets cannot prescribe CBD or freely offer advice about the products according to government regulations, but they can provide science-based opinions if you want to learn more about the efficacy of the cannabinoid. Overall, CBD is considered a safe treatment for dogs and cats, but until more research is conducted on dogs, the effects of long-term use of CBD products are unknown.

Quantity of CBD

When you shop for CBD drops for your dog, you’ll notice a significant variance in the CBD quantity of each brand. How much CBD is too much? Unfortunately, no one knows because CBD products have not been studied enough to establish proper dosage parameters for dogs or other animals.

Several manufacturers recommend serving one drop for every 10 pounds of body weight, and others suggest using two drops for every 25 pounds. Although companies have similar dosing recommendations on their website, they each have varying CBD potencies, and it’s challenging to determine which amount is suitable for your dog.

We suggest initially using a smaller dosage for your dog regardless of its size. CBD is relatively safe, but it’s wise to avoid using higher doses until you see how your pet reacts to the oil’s ingredients. Using a lower dosage will also save you money because the oils with higher potencies are surprisingly expensive.

Full Spectrum and Broad-Spectrum Oils

Most of the drops on our list are full-spectrum formulas, but a few manufacturers use broad-spectrum CBD. Most CBD products for pets, except one on our list, typically do not contain pure CBD or isolate CBD formulas. Isolate formulas only contain CBD and do not have additional cannabinoids or THC.

Full-spectrum products contain CBD and other cannabinoids from the cannabis plant, and broad-spectrum formulas include many of the same compounds but do not contain THC. Full-spectrum oils only have 0.3% THC, and they’re not supposed to trigger intoxicating effects or “highs” for dogs. However, we suggest the broad-spectrum type if you prefer using an oil without THC.

Added Flavors

CBD oil has an earthy taste when made with hemp seed oil, and some dogs may prefer tinctures with added flavors. Most of the flavored oils on our lists are all-natural, and some products use coconut oil or olive oil to make the tincture more appealing to dogs. If your dog is picky about its food, you may want to avoid unflavored hemp seed oil products. Some of the most common dog-friendly flavors include bacon, beef, and peanut butter.

Third-Party Testing

When researching CBD companies, look for producers that use private facilities unrelated to the CBD business to test their oil. Third-party testing ensures that the manufacturer uses sanitary methods and produces CBD without added pesticides or other hazardous chemicals. Since CBD oils and chews are not regulated like other FDA-approved products, testing is a vital process that every pet parent should expect from CBD companies.

Marketing and Science

After hemp and marijuana became legal in several states, the health and wellness and pet industries became flooded with CBD products. While researching CBD manufacturers, we found that some companies exaggerated the effectiveness of CBD as a medical treatment. We also found online articles that back up outrageous claims with studies conducted on humans rather than dogs or cats.

See also  Garden Of Life CBD Sleep Gummies

Before treating a dog suffering from cancer with CBD oil, remember that CBD products have not been proven to cure disease. If a company claims that CBD shrinks tumors or inhibits cancer growth, search the bottom of the article for reliable sources. We found an article that used this study to support CBD’s ability to inhibit cancer cells, and while the results are promising, mice were used as the test subjects rather than dogs.

Although few trials have been conducted on the effects of CBD on dogs with cancer, CBD oil may be useful in treating dogs with arthritis and reducing seizure frequency. Some pet parents suggest, from personal experiences, that CBD is effective in relieving symptoms associated with chemotherapy. Thankfully, CBD is safe for canines, unlike THC, but your veterinarian can help you decide if it’s appropriate for your dog. If CBD can improve the quality of your pet’s life, it’s worth trying, but start with smaller doses in the beginning.

Veterinary Advice

Because CBD is not approved for pets, veterinarians cannot prescribe oil or chews for your dog. However, you can talk to your doctor for an unbiased opinion about CBD products. Your veterinarian knows your pet’s medical history and is more qualified than anyone else to suggest cancer treatments.

CBD oil may help pets suffering from cancer, arthritis, and mobility issues, and several companies have created CBD oils specifically for dogs and cats. Our reviews highlighted the best CBD oils on the market, but our top choice was Royal CBD. We were impressed by the manufacturer’s commitment to product testing and liked the dosage options that are suitable for pups of all breeds and life stages. Our best value selection was CBD Pure, and we liked the low-dosage option for small dogs and the affordable price.

Using CBD Oil For Dogs with Cancer: What You Need To Know

Many of us are unfortunately all too well aware that cancer is a killer, but did you know it’s the leading cause of death in dogs ages ten and older? From risks to costs to decisions we’re never prepared to make, helping our dogs with cancer leaves many of us lost and confused. But we want you to know that experts believe about half of all cancers are curable. However, this is only if they are found early and given the proper treatment.

To help, we will be covering several major cancers common in dogs. We’ll go over the early signs and prevention of the cancer. Whether CBD for dogs with cancer can help and what the best CBD oil for cancer is. Last we’ll talk about how we can help dogs with cancer manage the side effects of common treatments like chemotherapy.

What is CBD Oil and How Does It Help With Dogs’ Cancer?

Known more formally as cannabidiol, full spectrum CBD is a cannabis-derived liquid that offers a myriad of health benefits for dogs with cancer. When cancer strikes, dogs are left to battle very draining side effects. It can become strenuous to fight cancer daily, but CBD is often said to be truly one of the few natural supplements that can help make the journey a bit more comfortable.

Just as people use medical marijuana to assist with health-related pain, pet CBD oil can be used similarly.

In a way, CBD is like medical marijuana for dogs that have cancer without the intoxicating effects. CBD helps with dog cancer in two main ways…

  • Provides symptom relief
  • Botanical extract supplement treatment options

Relief From Cancer Symptoms

One of the most appealing characteristics of full spectrum CBD for dogs with cancer is that it may help promote pain relief for dogs experiencing discomfort . There are many different side effects of not only cancer itself but of the methods of treating cancer in dogs, too. It can be incredibly difficult to watch our pets struggle with both cancer and the treatment for it. But stay rest assured pet parents, CBD may be able to provide a wealth of benefits. Such as better help with pain management.

The symptoms that each dog encounters will be unique to each dog, but some of the most common symptoms of canine cancer are:

  • Raised bumps under the skin
  • Difficulty breathing after exercise
  • Hard time breathing at leisure
  • Snoring or signs of sleep apnea
  • Unusual scents coming from the mouth
  • An odd-smelling coat
  • Open wounds that won’t heal on their own
  • Little to no appetite
  • No interest in eating favorite snacks
  • Excessive sleeping/naps
  • Low energy and disinterest in surroundings
  • Inability to urinate like usual
  • Clear signs of pain in your dog

Treatment Methods

It’s critical that dog owners remember that this is not a cancer treatment. For emphasis, CBD oil cannot treat cancer in dogs. It will not stop cancerous cells from growing, nor will it halt the progression of metastatic cancer cells in dogs. Instead of being a treatment, CBD is a way to relieve the not-so-great side effects of going through cancer treatment.

From chemotherapy and radiation to possible surgical removals and amputations, treatment options for dogs with cancer can become quite intense. CBD can be thought of as a healthy coping mechanism. By supporting pain and minimizing discomfort, CBD helps keep your dog comfortable while going through the motions of cancer treatment therapies.


When dogs become cancer-free after fighting cancerous cells in their body, they enter a phase known as remission. The hope is that your dog will stay in remission for the rest of their lives. Now, remember dog owners, just as CBD oil cannot treat cancer, CBD for dogs with cancer cannot prevent your dog’s body from growing cancerous cells in the future.

As amazing as this is for cancerous dogs, please consult with your dog’s veterinarian before administering full spectrum CBD oil to your pet consistently. Researchers and scientists are still trying to fully understand how CBD interacts with the endocannabinoid system of dogs and how it affects a dog’s health.

However, so far clinical trials are showing incredibly promising results. Abbreviated as the ECS, the endocannabinoid system is an internal network — similar to the immune system or the lymphatic system, to name some examples — that focuses on breaking down cannabis compounds.

Types of Cancer in Dogs

Not all canine cancer is the same. While there are more than only six types of cancer in dogs, we’re going to zero in on the most common canine cancers seen in dogs every year. These five types of cancer in dogs are:

  • Bone Cancer
  • Hemangiosarcoma
  • Lymphoma
  • Mast Cell Tumors
  • Melanoma
  • Mammary cancer

Bone Cancer

Osteosarcoma in dogs is a type of cancer that originates in the actual bones of dogs. Cancer is most often discussed in terms of surrounding tissues, but bones can develop cancerous tumors as well. Bone cancer arises when cells called osteoclasts and osteoblasts start reproducing rapidly to the point where it becomes an abnormal production rate. From there, the cancer cells form a conglomerate known as a malignant osteosarcoma tumor.


Canine hemangiosarcoma is a cancer of the blood vessels. As a malignant form of canine cancer, hemangiosarcoma can spread to other parts of the body. It doesn’t help that the tumors make a home out of blood vessels because they naturally move throughout the dog’s body.

Most often, cases of hemangiosarcoma are seen in elderly dogs, as well as middle-aged canines. In terms of breeds, smaller dogs are less likely to come down with hemangiosarcoma as it usually affects medium-sized to very large dogs.


Lymphoma in dogs stems from an abnormal production of cancer cells in the lymphocytes of dogs. Also known as the white blood cells, lymphocytes are leading players in canine immune systems. They are massively vital in making sure your dog’s immune system is strong enough to defend your dog against infections that threaten your pet’s overall health. The wellbeing of your dog has much to do with lymphocytes, so lymphoma can be daunting as it threatens white blood cells.

Mast Cell Tumors

Mast cell tumors are made up of cancer cells formed by abnormally produced blood cells. These tumors also happen to be the most common form of canine cancer. When the cells become deformed or otherwise transformed from their normal state, they mass produce and become malignant.

These tumors are very opposed to treatment, mainly because they grow back very quickly. Not only that, but they have a high propensity for metastasizing as well, so the earlier the tumors are detected in dogs, the better!


Melanoma is a type of skin cancer that manifests as dark spots on your dog’s coat. Unlike many cases of canine skin cancer , melanoma tumors are evident from the outside. It’s best to locate and treat melanomas as soon as possible because they can grow to become quite aggressive in a concise timeframe.

Mammary Cancer

Common in un-spayed female dogs and dogs spayed after their first heat cycle, mammary cancer is cancer in the mammary tissue. Dogs have five pairs of mammary glands, one pair near the front armpits, another on the upper chest, two pairs along the abdomen, and a final pair near the groin.

Most dogs show no signs related to a mammary tumor, however, they can bleed, and a dog might frequently lick the area. Instead, these tumors are most often found when the pet owner is petting their dog.

What Kills Cancer Cells In Dogs?

Cancer cells are incredibly difficult to kill without hurting the healthy cells around them. This is because the best treatments we have, struggle to distinguish between the good and the bad cells.

In some cases, such as skin cancer, the cancerous cells can be surgically removed without damaging the healthy cells. However, for most cancers, cancer drugs that damage the DNA and RNA of cancer cells, rendering them unable to divide, are needed.

See also  Pure Gold CBD Oil

The clever aspect of conventional cancer treatments like chemotherapy is they are attracted to killing cells that are in the dividing stage. While our healthy cells divide, cancerous cells divide uncontrollably at a rapid pace, resulting in tumors or masses. So while our best cancer drugs do unfortunately kill healthy cells and can be seen by some as an invasive treatment, they significantly kill more cancerous cells.

Is CBD Legal for Dogs?

Something that uncontrollably comes to mind when talking about CBD oil and other CBD products is the question of legality. Is CBD legal? And if so, are there parameters surrounding hemp oil for dogs? The last thing you’d want to do when trying to improve your dog’s quality of life is to break federal or state-level laws.

So, let’s take a look at the information surrounding whether or not CBD for dogs is legal. Technically, CBD is legal in every state within the United States of America. However, the one caveat is that the CBD and all related CBD products must be derived from a hemp/cannabis sativa plant, not marijuana. Both the hemp and marijuana plant are part of the cannabis family tree, but there’s a severe difference between the two plants.

In short, hemp plants are cannabis plants containing no more than 0.3% THC, whereas marijuana plants contain much greater THC concentrations. The fact that CBD oil must be hemp-derived in the USA works perfectly well for situations involving pets because CBD extracted from hemp is the only kind of CBD suitable for dogs.

What Effects Does CBD Have on a Dog?

Many dog owners find CBD has a calming sedative effect on dogs with cancer, providing natural relief. CBD is known for its healing effects, so soothing an anxious mind, minimizing the physical manifestations of stress, and calming an otherwise antsy dog are three examples of CBD’s effects at play. CBD does an excellent job of providing dogs with peace and tranquility during situations that would typically elicit the polar opposite emotional responses.

Hemp CBD oil works by interacting with the endocannabinoid system or ECS. The endocannabinoid system is responsible for regulating other regulatory systems like the nervous and immune systems. This is why CBD oil and other CBD products can help a dog’s endocannabinoid system, potentially lowering pain and inflammation, to name a few.

There is some thought that the endocannabinoid system can influence cancer cells by slowing their growth or hindering their ability to divide. However, our understanding of this is very young, and right now, it’s probably not much. As such, we never recommend CBD oil or another CBD product replace a cancer treatment advised by your vet.

Are There Any Negative Side Effects for Dogs?

Many people view the sedative nature of hemp CBD as being a positive effect on dogs that have cancer. CBD doesn’t usually make dogs tired unless too much oil is administered. When this happens, the relaxing effects of cannabidiol for dogs can be viewed as a negative side effect , especially when it’s not conducive for your dog to fall asleep.

Let’s say you’re taking your dog in for a follow-up after a recent chemotherapy appointment, but your dog happens to get very anxious in doctor’s offices. So, to combat the anxiety on top of the pre-existing physical discomfort from the chemotherapy, you decide to administer the oil to your dog. If you miscalculate the dose and give too much CBD to your dog, your dog will end up walking into their appointment in a deep slumber.

This is a moment in time where a seemingly positive effect of CBD turns into something inconvenient. But thankfully, this is an example of how the downsides of CBD oil for dogs with cancer are very minor. And it’s entirely preventable, too. Make sure you read the instructions and recommended dosing directions on the side of your CBD container for dogs. CBD dosages are based on body weight.

An Honest Look At CBD For Dogs With Cancer

In the large majority of cases, the biggest side effect a dog may experience with CBD is little to no benefits at all. However, cancer, along with common cancer treatments, can really wear down the body and ECS, causing a long list of side effects that CBD has commonly been shown to help — from loss of appetite to pain.

When discussing your dog’s treatment plan and cancer diagnosis with your vet, make sure to include CBD in the conversation if you’re interested in using it or another cannabis product. CBD oil is one of the common food/supplements that can mess with CYP enzymes and their ability to metabolize certain prescription drugs.

Like others, this usually occurs with higher than normal dosages. Most dogs with cancer respond well to CBD, and it fits into their treatment plan without any trouble or side effects of its own.

Are There Different Kinds of CBD for Dogs I Can Get Prescribed?

A prescription is not necessary for purchasing pet CBD oils or CBD dog treats. Buying this for canines with cancer has never been easier thanks to online companies like Innovet. Now, pet owners can buy CBD more efficiently than ever before. As pet owners, all you need to do is visit the Innovet website , select the products you think will benefit your dog, and complete your purchase!

You have the option of broad spectrum and full spectrum CBD for your pet owners. Either is fine, with full spectrum being the most widely used form of CBD oil for dogs and cats. Both broad spectrum CBD and full spectrum CBD are legally required to contain no more than 0.3% THC . This amount of THC pales in comparison to the 20-90%+ items you’ll find with marijuana products. This is why CBD products can’t cause a high when following hemp laws.

CBD Oils For Other Pets?

The benefits of CBD for dogs with cancer often get other pet owners wondering if it can help their cat or even their horse. While the majority of CBD research has been performed on humans, mice, and dogs, we’ve been able to gather that CBD essentially works the same for all mammals, thanks to the ECS.

Now there can be some differences between species due to variations in how they metabolize things and the make-up of their ECS. That’s why for any pet owner, it’s a great idea to discuss CBD with your veterinarian if you’re unsure about how CBD may affect your pet.

How Can I Get A Hold of CBD Oil?

With CBD able to improve your dog’s quality of life, you’re probably eager to try it. Look no further than the inventory at Innovet Pet. We have a wide array of CBD products for dogs with cancer to choose from, including:

  • Canine cannabidiol oil
  • CBD oils and creams
  • And more!

Our CBD oil comes in full spectrum instead of broad spectrum. Currently, with all the information we have, while broad spectrum CBD is great, it’s not the best for the extreme majority of dogs. The entourage effect of broad spectrum CBD just doesn’t compare to full spectrum, and that’s really important for

Is CBD the Best Option for My Dog?

When looking into companies that sell pet CBD marketed toward dogs, it’s essential to look at the quality control and overall process behind the making of CBD. You want to ensure that the CBD is tested by third-party laboratories to guarantee the CBD is of high quality.

Locally sourced hemp plants are best, so seek out CBD that is sourced in the United States. Last but not least, avoid CBD products containing preservatives, additives, by-products, or anything else.

Innovet Pet’s Full Spectrum CBD

Our full spectrum CBD oil for dogs is organic, hemp-based cannabidiol oil, which we source from the U.S. states of Colorado and Oregon. We create our CBD oil with your dogs in mind, meaning it’s 100% safe for your canine companions to consume. As a full-spectrum CBD product, the entourage effect ensures that your dog is getting the most out of every drop of oil from Innovet Pet.

Our products are manufactured in the U.S., but we trust our friends in Belgium with the hemp carrier oil that goes into Innovet CBD. Hemp oil is even seen as preferable over MCT coconut oil. Everything about our pet CBD for dogs is legal in the U.S. so you can place your orders online without any hesitation! Did we mention our CBD is entirely natural?

That’s right! There’s not a single pesticide, GMO, by-product, additive, or preservative in our CBD for dogs. Because we think hemp is amazing enough on its own, we choose hemp seed oil as the required carrier for CBD oil. In fact, not only is hemp wonderful enough on its own, hemp seed oil is the smarter choice vs. MCT oil which lacks nutrition and is higher in bad calories.

Other CBD Products For Cancer Treatment

Besides our CBD oil, we have our dog treats, hemp-based creams, and capsules, great for help with loss of appetite and general health, along with pain and inflammation. We recommend CBD oils first only because it makes administering CBD and customizing the dosage the easiest.

You can directly give it to your dog or mix it into your dog’s food. Although research on the use of CBD for dogs with cancer has mostly been performed with CBD oils, any form of CBD, like CBD dog treats, should provide the same range of benefits.

Final Words CBD Oil Use For Cancer

We want to stress the importance of not using CBD oil and hemp oil as a sole treatment for cancer and that much of the proclaimed benefits come from anecdotal evidence. CBD oil may have anti-cancerous effects, but research about how significant is unknown. CBD treatment is great for improving the quality of life when a dog is undergoing cancer treatment, such as chemotherapy or radiation therapy. However, it is not the sole replacement for your dog’s cancer treatment plan.
