CBD Oil for Dogs: 8 Key Things to Know

CBD oil is a fast-growing market and the compound is now being touted as a treatment for dogs too.

Indeed, the therapy is already big business, with a study by Grand View Research estimating the market size for CDB oil surpassed $37.4 million as of 2020.

However, the American Kennel Club’s (AKC) Chief Veterinary Officer, Dr. Jerry Klein, cautions while CBD oil boasts potential benefits for dogs, owners should always consult their veterinarian before starting such medical treatments.

He told Newsweek: “Cannabinoids such as CBD appear to hold therapeutic promise in areas such as the treatment of epilepsy and the management of pain and inflammation associated with osteoarthritis, neurogenic pain and possibly anxiety although much of the available scientific evidence pertaining to their use in animals is currently limited.

“While findings from a few well-controlled studies have been published, much of what we know is related to anecdotal or case reports.

“It is of utmost importance for people to know that CBD is not marijuana which is TOXIC to dogs and should never be given to dogs under any circumstances.

“Additionally, it is always recommended consulting with your veterinarian before starting and medication or supplements as your veterinarian best knows your dog’s individual medical history and needs.”

Here are some of the most important facts you should know about CBD oil for dogs.

1. What Is CBD Oil?

While CBD, or cannabidiol, is a compound found in cannabis and hemp, the oil it is derived from rarely contains delta-9-tetrahydrocannabinol (THC), the compound responsible for providing marijuana its psychoactive properties.

Note, hemp-derived CBD oil products (with less than 0.3 percent THC) are legal on the federal level, but are still illegal under some state laws.

2. Does CBD Affect Dogs?

Currently, there has been no formal research conducted about how CBD oil affects dogs.

However, research has shown cannabinoids interact with the endocannabinoid receptors located in the central and peripheral nervous systems, which help maintain balance in the body and keep it in a normal healthy state.

3. What Dog Health Problems Might CBD Oil Treat?

Although definitive scientific data on using CBD to treat dogs is still lacking, the AKC states “anecdotal evidence from dog owners suggests it can treat pain, especially neuropathic pain, as well as helping to control seizures.”

CBD is also used by humans for its purported anti-inflammatory properties, cardiac benefits, anti-nausea effects, appetite stimulation, anti-anxiety impact, as well as potential anti-cancer benefits, although conclusive data on this use is also lacking.

4. Potential Side Effects of CBD Oil in Dogs

Due to the lack of scientific data on the side effects of CBD usage for dogs, experts can only speculate about the possible side effects based on how the compound can affect humans.

Research suggests CBD can decrease the production of saliva. The AKC said: “For dogs, this would manifest as an increased thirst.”

High doses of CBD have been known to cause a temporary drop in blood pressure, capable of triggering brief light-headedness.

Humans have used CBD on their pet dogs to treat anxiety, while CBD oil’s calming effect can also cause slight drowsiness.

The AKC cautions in a statement: “To minimize any potential side effects, make sure you are following the proper dosage.”

5. Potential Risks of Using CBD Oil With Dogs

The safety and risks of using CBD for dogs have not yet been researched and the U.S. Food and Drug Administration has neither approved CBD nor issued a dosing chart.

As a result, it remains unclear what size dosage of CBD oil would be toxic for dogs.

The AKC warns any medication or supplement carries the risk of a reaction, writing on its site: “It is always advisable, when giving your dog something new, to start with small amounts and then closely monitor the effects. And always check with your veterinarian first.”

6. Can Dogs Taking Medications Use CBD Oil?

Owners of dogs taking any medications or supplements should always check with a vet.

CBD oil can change how the animals metabolize some drugs, in the same way that grapefruits can cause significant reactions in humans.

Owners will need to consult their vet about dose changes if a dog is taking any of the following medications: steroids, allergy medications, liver or kidney medications, non-steroidal anti-inflammatory drugs, heart medications and anxiety medications.

7. CBD Dosage for Dogs

Each bottle of CBD has a specific concentration expressed in milligrams. Some owners add CBD oil to their dog’s food.

Dr. Robert Silver from NurseYourPet suggests giving a dog 0.05 to 0.25 mg/pound of body weight, twice daily is a “safe place to start,” as well as suggesting beginning with lower doses and increasing these only gradually if the lower dose appears ineffective.

It is important to note, that is only from his anecdotal experience.

8. What Are the Best CBD Oil Products for Dogs

Should consultation with a vet result in a decision in trying CBD oil to treat your dog, there are some key things to consider when buying the compound.

The AKC states: “Not all oils are the same; you’ll want high-quality CBD oil to have a better chance of it working.”

If the CBD oil is not organic, it at least should not contain pesticides, fungicides, or solvents.

Higher quality and purity are usually associated with a higher cost, meaning cheaper options can potentially more likely contain toxic substances including pesticides, herbicides, or heavy metals.

The manufacturer should provide a certificate stating the quantity of CBD in the product, with some CBD products containing minimal amounts of CBD. People buying CBD oil for their pet dogs will also want to ensure there is little or no harmful THC in the product.

The AKC also advises people to purchase CBD as a liquid whenever possible, stating: “You can buy dog treats containing CBD, but the best form to administer is an oil or tincture. This way, you can adjust your dog’s dose drop by drop.”

The Side Effects of CBD Oil for Dogs and Cats

The health benefits of CBD (cannabidiol) have made it all the rage lately. More and more people and pet owners are beginning to uncover the magic of CBD products like CBD oil and pet CBD treats and all of their natural healing properties and benefits.

Before giving your dog CBD, you need to know what CBD is, the role it plays in health, etc. As well, you need to know that research regarding CBD and its benefits, along with the potential side effects, has not been heavily investigated in many dog and cat studies. Most of the participants of research on CBD and CBD products side effects have been people with animal studies mainly on rats. As such, if you’re interested in using CBD oil for yourself, this article will have a lot of information for you. Many pet owners are taking CBD just as much as they are giving it to their dog or cat.

However, Something to keep in mind is that cats, dogs, and people have very similar immune systems, brain pathways, and internal organ functioning. These minor different though incredibly similar commonalities mean that people parallel cats and dogs more than you might have previously thought. The few studies on CBD and dogs back this up.

With people responding to CBD in the same way that dogs and cats do, the outcomes of research and studies that focused on people’s use of CBD can be applied to the reactions that pets have to CBD. But the question remains: are CBD products safe for our pets?

As a pet owner, your biggest concern when it comes to your cat or dog is always their health. It can be scary to think about introducing something new to your pet without knowing everything there is to know about the product, especially when it comes to CBD oil. Don’t worry we were the same way.

To release the hesitation and fear associated with trying CBD oil for cats and dogs, we suggest staying up-to-date on the latest findings and most current information. After all, there is already such a discrepancy between what people believe about CBD oil for pets and what is actually true of the substance.

How do you know if your pet will react positively to CBD oil? Well, you will never truly know until you give it a try, but our article will leave you calmer and more assured if you opt into CBD oil for dogs and cats or another similar CBD product. First, let’s dive into CBD oil and what it really is, and then we can talk more about the potential side effects of CBD and CBD products on dogs and cats.

Before using CBD oil for yourself or giving your dog CBD, it’s important to understand what CBD is. CBD is the shorthand version of a substance and a cannabinoid compound called cannabidiol. Since CBD is still on the rise, there are many misunderstandings that surround this plant-based soothing oil. As an alternative to THC, or tetrahydrocannabinol, CBD can’t cause a high and presents significantly lower potential side effects.

In total, there are 113 known cannabinoids that have been found in cannabis which includes both hemp and marijuana plants to date. While CBD is derived from cannabis plants and sometimes marijuana plants, this is not what causes the feeling of being high that people associated with marijuana and cannabis. Marijuana itself does not cause changes in the brain, and subsequently, in the body. Instead, the actual cannabinoids that are extracted from these plants are what does or does not create the feeling of being high.

But believe it or not, out of all the cannabinoids, there is only one cannabinoid found in cannabis that’s concentrated enough that, when consumed, causes the high sensation. That cannabinoid is tetrahydrocannabinol, which CBD products legally have to contain little to no THC. In the U.S., CBD products are legally allowed to contain trace amounts of it(0.3% or less). This is why it’s usually derived from hemp as hemp is naturally low in THC vs marijuana. Never will this percentage be enough to create psychoactive effects in your pets and nowhere near enough to cause a toxicity. But it is good to be aware of your pet’s reaction to even the smallest doses of THC as they are possible side effects with it.

If your dog or cat has negative reactions to even the smallest amounts of THC, hope is not lost. Instead of looking for CBD, you can modify your search for pure CBD oil for pets. Pure and organic CBD comes straight from the hemp plant, rather than a marijuana plant. Hemp greatly eradicates any possibility that the CBD oil for dogs and cats can contain enough THC for possible side effects. Then, a reputable company will test their CBD for absolute safety.

Since there is often a lot of confusion regarding the difference between hemp and marijuana plants, the assumption tends to be that CBD produces a body and mind high, just like THC. This is very inaccurate, however. CBD creates the calming effects that THC often ignites, though THC can sometimes provoke the opposite effect and cause a pet, or even a person, to become overly anxious and hyperactive. Since this is the exact behavior people are trying to achieve, THC can pose a risk of your pets experiencing an adverse reaction.

Both THC and CBD work with the endocannabinoid system with CBD working naturally with the endocannabinoid system by mirroring self-created endocannabinoids. THC, on the other hand, pushes the endocannabinoid system past what’s naturally possible.

The biggest bonus of CBD oil is that there are very few side effects involved. Even better, nothing about CBD oil is fatal. An extremely high dose of CBD oil won’t lead to accidental death, simply due to the nature of CBD. This is not true for THC, as dogs are significantly more sensitive to it.

There are a few side effects of CBD for dogs and cats that you should know about:
  • Increased levels of fatigue and sudden exhaustion
  • Uncharacteristic tiredness during daily activities
  • Drowsiness and loss of total muscle control
  • Decrease in paw-eye coordination
  • Thirst levels increase due to dry mouth effects of CBD oil
  • Slower heart rate and decrease in blood pressure as CBD oil sets in and body calms down

Essentially, CBD oil can cause your pet to feel sleepier than usual. In most cases, this just means that you should give them a lower dose of CBD oil next time. Also, if your dog or cat is not feeling particularly anxious, rowdy, or ill on a given day, the CBD oil may affect them more, making them even more tired. It’s a process of trial-and-error, but hopefully, it comforts you to know that the side effects of CBD oil for pets are very mild to non-existent for most. Some dry mouth is by far the most common complaint.

Due to the temporary decrease in blood pressure, CBD may not be viable for a dog or cat with glaucoma. As well, ask your vet about CBD if your dog or cat is on any prescription medications that are metabolized in the liver. Last, because cannabis, including hemp, is a phytomediate plant, organic is always the way to go to avoid contamination from minerals that jeopardize the quality and safety of cannabidiol.

Now that you know about the side effects of CBD oil, you might be wondering about the risks associated with CBD oil for dogs and cats. Well, we are pleased to let you know that there are little to none.

This might sound too good to be true, but trust us when we tell you that there are little known risks of CBD oil for pets. The biggest detrimental aspect of CBD is that the research of CBD side effects on dogs and cats is low. However, the findings gathered from research with humans and CBD has been applied to CBD oil for pets with confidence and backed by individual experiences.

The most comforting aspect of CBD oil is that the effects fade eventually. Depending on the dose you administer to your pet, the side effects can start to wear off within an hour, sometimes less when the dose is very low. However, CBD oil is nothing but natural medicine for your pet.

CBD oil for cats and dogs is…
  • All-natural
  • Non-toxic
  • More readily accepted by the body than many prescription drugs
  • Can’t cause a high
  • Impossible to OD on CBD

Because the use of CBD can help maintain general health along with its anti-inflammatory benefits and to help treat chronic pain, it has set off a flood of companies looking to make a quick buck off the popularity, jeopardizing the safety of CBD. This includes companies that make CBD for humans and those for animals.

When looking into companies that produce and sell CBD for dogs and cats, you will want to do some research. Cannabis is an incredible plant, but especially with pets, marijuana can complicate some things. If you are eager to try CBD oil for your pets after looking into the health benefits, both mental and physical, then there are a few things to keep in mind.

Before giving your dog CBD oil products, know that your pet’s age and weight will play a role in how much CBD oil you should give your cat or dog at once. While nothing life-threatening will happen to your pet should you accidentally administer a higher dose than necessary, your pet may become very tired and want to go off and sleep. Now, using CBD at larger doses is fine. For some users, this is the desired outcome, and prefer a high dosage of CBD. But most cats and dogs don’t have issues with getting enough sleep so dosages tend to stay lower. As well, higher doses can bring out heavier CBD side effects.

Side Effects of CBD Oil in Dogs

CBD is more popular than ever. Touted as a miracle cure for everything from anxiety to nausea, it won’t surprise most pet owners to find that there are plenty of businesses getting into the CBD space for pets as well as humans. If you’ve spent at least a few minutes looking at the best CBD oils for dogs, you already know that there’s no shortage of information out there. You may, however, also feel quite overwhelmed by all of the often contradictory data that’s available online.

Most pet owners are more than happy to do the research when it comes to pet products. After all, they want the best for their dogs and would never want to give their pets anything that could possibly hurt them. That’s why it’s so important that you spend some time reading up on the possible side effects of CBD oil in dogs before you decide on any CBD product.

Learning more about the side effects of CBD oil on dogs requires not just fear, but a bit of intellectual curiosity. You need to start by figuring out the potential benefits of CBD oil for dogs, then figure out whether the potential side effects are worth the risk. Fortunately, we’ve done the digging to help figure out exactly what you need to know about how these products can interact with your dog’s body.

Understanding CBD Oil

One of the most important things you can do as a pet owner is to try to take the time to understand what you’re putting in your dog’s body. CBD is no different than any other compound, in that you’ll need to know what it is, what it does, and how it can impact your dog before you use it in any type of treatment plan.

CBD oil relies on a compound called cannabidiol in order to work. This compound, found in both hemp and cannabis, isn’t the same thing as the compound that gives cannabis its notable psychoactive effects. In fact, CBD is routinely used for a number of medical uses and, unlike THC, it has been legalized for use across the United States.

Because CBD oil has either no THC in it or only trace amounts of that compound, it’s generally safe to give to your pets. It’s always a good idea to look at the individual product, of course, but most are going to be effective enough to make the average dog owner feel comfortable.

What Are the Effects of CBD Oil on Dogs?

One of the most important things you can know about CBD oil is that there aren’t actually all that many studies about how it impacts the health of dogs. While there are almost certainly some ongoing studies at the moment, this just hasn’t been one of those areas of research that’s been particularly well-funded over the years. As such, it’s almost impossible to say precisely what the impact of CBD is going to be on your dog from a purely objective standpoint.

If you’re willing to take more anecdotal evidence, though, you’ll be happy to know that a number of researchers who have begun looking at the impact of CBD on dogs have noted that the actual impact of the compound on dogs is generally positive. These compounds mostly impact the nervous systems of your dog, helping them to stay healthy and alert – definitely a good thing for most dogs.

What is CBD Oil Used For with Dogs?

CBD oil often feels like one of those compounds that are used for everything. It is commonly used for ailments like arthritis, of course, but it is also used for a number of other issues like separation anxiety and even to provide dogs relief when they suffer from illnesses like cancer. Though there aren’t necessarily enough completed studies to say exactly how CBD can be effective as a specific treatment, there are enough dog owners who swear by the substance to make the average dog owner at least a little bit interested.

It’s probably fair to sort the positive effects of CBD into three different categories. The first is the soothing effect – it helps to reduce anxiety and stress while helping to keep negative behaviors under control. The second is the regulation effect, which helps dogs to avoid mood swings and helps to eliminate wild emotional reactions. The final, and often most important, factor is the pain mitigation factor, which helps dogs to feel less pain whether they’re recovering from surgery or dealing with a long-term illness.

The biggest issue for many concerned pet owners is that there’s just not enough information about CBD out there yet. Studies are forthcoming and promising, of course, but it’s from these studies that we are most likely to get the necessary information about not only the positive effects of CBD oil but also the negative side effects for which pet parents should be on the lookout.

What are the Side Effects of CBD Oils for Dogs?

While CBD oil can and often is a fantastic treatment for many types of conditions, it’s not currently at the point where the FDA approves it for any kind of treatment. As such, you’re going to be dealing with a substance that isn’t as highly regulated or studies as many others on the market. To understand what you might be getting into, you’ll need to look at some of those same studies in the process that tout the beneficial effects of CBD oil for dogs.

One of the scariest-sounding side effects of CBD oil for dogs is that it can lead to an elevation in alkaline phosphatase in your dog’s liver. Though this might be a frightening statement, those same researchers aren’t actually sure what that means for your dog in a medical sense. It certainly could end up being something quite negative, but at the same time, it could be something that’s possible to ignore.

More pressing is the fact that CBD oil could have some bad interactions with other drugs. We already know that CBD can have negative interactions with anti-inflammatories, for example, so it’s worth looking at least talking to your doctor about CBD oils if your dog is on any other kind of medicine.

While those are the two great unknowns in terms of side effects, there are a few others that have more anecdotal data behind them. These are the side effects for which most pet owners should be on the lookout.

Dry Mouth

Dry mouth is one of those issues that are already fairly well-known when it comes to CBD products in humans, but it’s also one that can impact your dog. While you might not know this already, salivary production is actually a much bigger deal for dogs than it is for humans. After all, your dog’s saliva aids in digestion and dental health, as well as other bodily functions. If your dog doesn’t produce enough saliva, he or she is going to end up fairly unhappy.

So, what happens if your dog gets a dry mouth? Generally speaking, he or she is going to start drinking a lot more. That might not seem like a bad thing, but it’s not actually a solution to your dog’s problem. The lack of saliva production can still cause damage, so you’ll want to immediately respond to a dryer dog mouth by ensuring you’re at an appropriate CBD dosage for dogs. If this doesn’t help, you’ll need to stop giving your dog CBD oil until you can get him or her to the vet.


Vomiting is never a good thing. It’s a normal side effect of CBD oil, though, and it’s not necessarily one that has to do with any bad interactions. CBD oil doesn’t always taste great and getting a CBD product that doesn’t have any kind of flavoring might make your dog choose to reject the product entirely.

With that said, you do want to make sure that the vomiting is something that’s caused by taste rather than the compound itself. If your dog throws up immediately as the CBD oil hits his or her tongue, you don’t have much to worry about. If your dog throws up sometime after he or she has swallowed the CBD oil or CBD product, though, you’ll want to pay careful attention to his or her behavior. This kind of side effect is one that could be very serious.


Diarrhea is another one of those side effects that you never really want to see. Again, it’s another one of those problems that never seem to be all that easy to diagnose. Diarrhea and dogs tend to go together somewhat naturally, as many dogs will eat plenty of things that make their own stomachs sick. Unfortunately, though, this means that you’re going to have to go through some trial and error to figure out if this is an actual side effect of CBD oil.

The easiest way to figure this out is to stop giving your dog CBD oil. In fact, you’re going to need to go to the blandest, most normal version of his or her diet as possible. Once your dog resumes having normal stool, you’ll be able to re-introduce CBD oil. If there are no problems, the cause of the diarrhea was not the CBD oil.

What do you do if your dog does have diarrhea because of the CBD oil? First and foremost, discontinue the CBD oil for the time being. Give your dog a bland diet, make sure that he or she has plenty of fluids, and keep an eye on your dog to determine whether or not he or she needs to go to the vet. If you do feel like reintroducing CBD oil is a good idea, make sure that you give it to your dog a significantly lower dose. Once you reintroduce the oil, start monitoring for signs of distress – if your dog continues to have stomach problems, CBD oil may not be the right choice for him or her.

Sluggishness and Lethargy

One very common side effect of CBD oil for dogs is lethargy. Your dog might slow down a little bit, acting more sluggish and maybe even sleeping a little bit more. While this isn’t necessarily always going to be a bad thing, it’s still something that you should talk about with your vet. This change in behavior could actually be because your dog’s blood pressure has dropped, which would mean that you need to discontinue using CBD oil products as soon as possible.

Is it Worth it to Use CBD Oil for Dogs?

Given the side effects of using CBD oil, it does make sense that you might be at least a little bit nervous about choosing to use CBD oil for your dog. After all, you would never want to do anything that could hurt your pet and you certainly don’t want to take unnecessary risks. What you do want to do, though, is to think about whether the benefits still outweigh the risks of side effects.

CBD oil is one of those products that treat things that might otherwise leave your dog in distress. From sleeping issues to mood regulation, CBD is thought to do a number of things that other drugs simply cannot match. While there’s certainly no such thing as a drug without side effects, it’s vital that you decide whether CBD’s benefits are enough to risk the problems that he or she might have with the products.
