CBD Oil for Dogs: What You Need to Know

People have been using cannabis and cannabis-derived products to treat illnesses and ailments for thousands of years, but the popularity of medical marijuana has exploded over the last decade or two. Given the encouraging results many people have enjoyed, some owners and veterinarians have begun using CBD oil for dogs.

So far, the results have been mixed – just as they have been for humans using medicinal marijuana. Some owners claim that their dogs have benefited greatly from cannabis concoctions, while others have been disappointed by the lack of results. Still others have reported concerning side effects after using these substances.

You’ll have to work with your veterinarian to determine if cannabis would be part of a good treatment strategy for your dog, but we’ll walk you through the basics below. We’ll explain what CBD oil is, the ailments it is thought to treat, potential side effects and more, so that you can try to make the best decision possible for your canine.

What Are Cannabinoids?

Cannabis plants contain varying amounts of compounds called cannabinoids. These chemicals interact with the human endocannabinoid system (more on this below), causing a variety of different biochemical changes. Tetrahydrocannabinol (THC) is the most famous cannabinoid, and it is the one primarily responsible for the psychoactive effects of marijuana.

Cannabidiol (CBD) is another cannabinoid found in most cannabis plants. Unlike THC, CBD does not produce significant mind-altering effects. In fact, some research suggests that it works to counteract the effects of THC. However, CBD appears to be very effective for treating pain and inflammation in some human patients.

There are other cannabinoids found in cannabis plants (85 have been identified to date), but THC and CBD are two of the most important for growers, consumers and patients.

The Endocannabinoid System

The human body contains a series of chemicals and receptors called the endocannabinoid system. This system is responsible for regulating a number of different bodily functions, including mood, appetite and pain sensation. The body makes its own cannabinoids, but those found in cannabis plants also interact with the receptors to produce similar effects.

And as it turns out, humans aren’t the only animals with an endocannabinoid system. In fact, most mammals have similar systems. This means that administering cannabinoids to dogs may provide them with some of the same effects humans enjoy.

There are two basic types of endocannabinoid receptors, dubbed CB-1 and CB-2. CB-1 receptors are primarily found in the brain and are primarily triggered by THC; CB-2 receptors are found throughout the body and primarily interact with CBD. When a human ingests THC, for example, the receptors become stimulated by an excess of cannabinoids, which causes the person to feel high or hungry. Conversely, when a person ingests CBD, they often enjoy a reduction in pain and inflammation.   

What Is Hemp?

Hemp is a plant that is closely related to marijuana, yet it has a few important differences. But to understand hemp and how it differs from marijuana, you need to learn a little about the cannabis plant first.

There are three species of cannabis plant:

  • Cannabis sativa
  • Cannabis indica
  • Cannabis ruderalis

Cannabis sativa and Cannabis indica are the two species most commonly used for medicinal, recreational and industrial purposes. Cannabis ruderalis, by contrast, is not cultivated on a large scale, as it lacks the size to be valuable for industrial purposes, and it lacks significant amounts of the psychoactive chemicals found in Cannabis sativa and Cannabis indica. However, it is occasionally crossed with the other two species by cultivators, who prize its insect and disease resistance, among other things.

Hemp is a variety of Cannabis sativa, but it has been selectively cultivated to suit industrial, rather than recreational purposes – primarily the production of fibers. Humans have been cultivating this fiber-rich variety for more than 8,000 years, and it has been used by a variety of civilizations all around the globe.

In the modern era, hemp has not only been cultivated with an eye toward improving its fiber-producing abilities but also with the goal of reducing the amount of THC present in the plant. This makes the plant easier to handle from a law-enforcement point of view, and a few states allow for the commercial cultivation of the plant. However, most farms permitted to grow the plant must only produce strains that have very low levels of THC – generally on the order of 0.2 percent or less.

However, while hemp contains very little THC, it is often rich in CBD. As CBD does not produce psychoactive effects, cultivators never went to the trouble of reducing the amount present in their plants. Accordingly, hemp is commonly used as a source of CBD for the medicinal marijuana industry.

CBD Oil for Dogs: Legal Environment

Several states have allowed people to use medicinal marijuana for the past few decades, but beginning in 2008, the dam started to break and a number of states began allowing recreational use. Currently, eight states and the District of Columbia allow recreational use and 29 states allow for some type of medicinal use. This changing legal environment has partly spurred owners and vets to begin trying CBD oil for dogs.

Nevertheless, the federal government still lists marijuana as a Schedule I drug, alongside heroin, LSD, and others. And while hemp is a legal product for licensed farmers to grow, and you can frequently find bracelets and other goods made from hemp fiber for sale at your local mall, CBD oils are still considered illegal at the federal level. The FDA has not approved any of the commercially produced CBD-oils for pets, and many state veterinary licensing boards also prohibit vets from prescribing them for their patients.

This all means that you may want to tread carefully when ordering some CBD oil for your dog.

What Types of Ailments Does CBD Oil Treat in Humans?

Research into the medicinal applications of CBD is still in the early stages, but the evidence does suggest that it has bona fide medicinal value. Some of the things CBD is thought to treat in humans include:

  • Inflammatory Conditions
  • Parkinson’s Disease
  • Alzheimer’s Disease
  • Osteoporosis
  • Muscular Dystrophy
  • Hypertension
  • Osteoarthritis
  • Chronic Pain
  • Nausea
  • Diabetes
  • Post-Traumatic Stress Disorder
  • Epilepsy
  • Crohn’s Disease
  • Anxiety
  • Depression

There are varying amounts of evidence supporting the use of CBD to treat the conditions listed above. Some studies have found CBD helpful for treating some of the symptoms listed above, while others have failed to demonstrate a correlation between CBD oil and symptom reduction.

It is important to note that while THC is typically used for recreational, rather than medicinal purposes, the psychoactive cannabinoid does appear to help alleviate the symptoms of a few conditions, including glaucoma and Tourette’s syndrome.

What Conditions Does CBD Oil Treat in Dogs?

There hasn’t been much research investigating the medicinal benefits of CBD hemp oil for dogs. Nevertheless, many pet owners and veterinarians use it to treat some of the same ailments the drug is used to treat in humans, and anecdotal accounts of success abound.

Some of the most common conditions CBD Oil is used to treat include:

  • Osteoarthritis
  • Anxiety
  • Nausea
  • Seizures
  • Cancer complications
  • Pain (especially of the chronic variety)
  • Gastrointestinal ailments
  • Inflammatory conditions

What Do Vets Have to Say About the Use of CBD Oil?

Vets are a mixed bag when it comes to CBD oil. Some enthusiastically encourage their clients to try it, while others remain reluctant to encourage its use. Some are probably conflicted by the murky legal ground they find themselves on when speaking about Cannabis-based products, so it is difficult to determine the consensus opinion.

However, the majority of vets appear to be hopeful that CBD will prove to be a viable medical treatment, while still remaining cautious about prescribing it for their patients. As explained by veterinarian and board member of the Evidence-Based Veterinary Medicine Association, Brennen McKenzie:

“We have virtually no research in pets, so we are guessing and extrapolating.”

But other vets lack McKenzie’s skepticism and encourage owners to use CBD oils to treat ailments that have proven difficult to treat with conventional medications.

The very nature of veterinary care further complicates the issue, as pets can’t tell us if the medicine they are taking is helping or not. Instead, owners and vets must attempt to determine the efficacy of many medications – including CBD oil – by interpreting the behavior of the dogs being treated. This, it turns out, is not always reliable.

For example, a 2012 study found that many owners reported that a standard osteoarthritis medication helped to improve their dog’s mobility and reduce the pain associated with the condition. The only problem? More than half of the owners who reported an improvement in symptoms were mistaken – their dog was only prescribed a placebo.

Because the placebo effect can strongly influence the results of cannabinoid-related studies, some scientists have taken steps to verify that dogs can even absorb CBD oils when they are administered orally. Unfortunately, the initial research suggests that they cannot – at least not very effectively. This means that many of the reported health benefits of CBD oil may be nothing more than wishful thinking on behalf of owners.  

Those who do recommend CBD for their patients (or speak in hypothetical terms to avoid actually recommending its usage to their clients) typically encourage owners to start very slow, and administer very well-measured amounts.

A CBD oil has been produced specifically for use in pets. Called VetCBD, this medication has a 19 parts CBD for every 1-part THC.

The Entourage Effect

Some medical marijuana advocates, doctors and vets favor the use of hemp in the commercial production of CBD oil, but others suspect that derivatives of hemp plants are not as effective as those which are processed from psychoactive Cannabis strains, which have had the THC removed in a laboratory.

This school of thought is based on the purported “entourage effect.” The entourage effect refers to the combined action of the various cannabinoids and terpenes (chemicals also found in Cannabis plants), which is thought to produce medications that are more effective than the sum of their parts.  

However, this can be risky. The regulation of cannabis-based products varies greatly from one state to the next, and it is not always clear that you are getting what you think when you purchase a cannabis-based product. This could be very problematic if you obtain a medication that contains too much THC.

Dogs can and do get stoned, and it isn’t always cute or funny – some become quite distressed or disoriented, and some may fall ill. Don’t forget that most authorities consider Cannabis plants toxic to dogs. A few dogs have even died after eating THC-infused edibles.
