Is CBD Oil Toxic for Dogs? - A Scientific Analysis

CBD oil is the new kid on the block when it comes to plant based derivitives but has been able to turn heads around the world. Scientists have just begun to discover the therapeutic value of CBD that applies to both humans and pets. From pain management to better sleep, CBD can have excellent benefits for your dogs.

However, the research on CBD is in its nascent stage without much literature to rely on. It is only after the Farm Bill of 2018 that scientists began to study the cannabis plant. As more states legalize cannabis, we can hope for research on the magical plant to grow and reach solid conclusions.

Till then, we have to rely on what’s out there to resolve our queries, like-

Is CBD oil toxic for dogs? Can your pet die from taking CBD?

In this blog, we will explore if CBD is toxic to dogs based on scientific evidence. You will also learn:

  • Can CBD oil kill your pet?
  • Is CBD oil risky for dogs?
  • What are the side effects of CBD oil?
  • What to keep in mind while giving CBD oil to dogs?

We will begin from the start and go into details step by step to make you more aware.

Can Cannabis Cause Death?

CBD oil is a product of the hemp plant. Therefore, many pet owners worry CBD may harm their dogs or even cause death.

Is this a fact or a figment of our imagination?

When in doubt, we should always take the refuge of science. If you do a simple Google search, you will see all resources, biased or not, say marijuana won’t kill you. Of course, you should rely on reputed resources that back their claim with evidence.

So, let’s get one thing out of the way before we proceed with our blog. Smoking or ingesting cannabis cannot cause death in humans. Or in other words, CBD cannot kill us.

You can do your research and see if you can find any contradictory claims. We bet you won’t since so many states wouldn’t have legalized marijuana if it had any negative health consequences. 

Now, let’s find out if the same is true for dogs.

Can Cannabis Kill Your Dog?

Animals and humans differ in many aspects. As a result, cannabis doesn’t affect us and our pets in the same way. Therefore, pet parents are justified in having second thoughts about using cannabis products like CBD oil.

However, let us put your worries to rest. Dogs cannot die by consuming cannabis or edibles, even in cases of overdose.

According to Kaiser Health News, marijuana can never kill your dog. The news portal interviewed many vets, none of which ever encountered a pet death due to marijuana toxicity. In addition, cannabis won’t cause liver, renal, or any other organ failure in dogs.

The only way they can die is by getting sedated and inhaling their vomit.

Therefore, CBD oil will also not harm your dog as it is a product of the cannabis family. You will find ample resources online to confirm our conclusion.

So, we will move on to our next section as we have to keep things concise!

Is CBD Oil Toxic for Dogs?

CBD won’t kill dogs, but would it cause toxicity?

CBD oil can be made from hemp or marijuana plants. However, most CBD products for pets come from the hemp plant instead of cannabis.

What is the difference between hemp and cannabis plants?

Hemp plants cannot contain more than 0.3% THC by law. THC is the substance in cannabis responsible for making us high.

Additionally, THC is also the culprit for most marijuana toxicity in dogs. 

However, CBD oil derived from hemp contains a negligible THC (0.3% or less). As a result, hemp CBD or products are safe for animal consumption.

Your dog can experience toxicity only if it takes CBD oil made from marijuana that contains considerable THC. For this reason, you should always stick with CBD oil made for pets, especially dogs, for utmost safety.

The World Health Organization (WHO) also says pure CBD seems to be well-tolerated and safe for animals. So, you can give CBD oil to your dog with complete peace of mind.

Look for a Certificate of Analysis

CBD products in the market are not under the regulation of the FDA. As a result, any CBD oil can have ingredients that are not listed on the label. These undisclosed ingredients may turn out to be harmful to your pets or cause undesired effects.

Therefore, always look for CBD oil that comes with a certificate of analysis. You should also ensure the certificate is for the current batch to avoid any unpleasant surprises.

Generally, most reputed manufacturers provide certificates from third-party labs on their websites.

Is CBD Oil Risky for Dogs?

CBD oil is not toxic and also doesn’t kill your pets. Additionally, your dog won’t get intoxicated as long as you stick to CBD products for pets.

But are there any other health risks of CBD?

As we noted earlier, CBD oil is safe for healthy dogs. It will not cause any adverse effects to put your dog’s health at risk.

However, some people have a concern that CBD may increase liver enzymes in dogs. It is metabolized in the liver and can spike alkaline phosphatase (ALP), a marker of liver disease.

Fortunately, scientists have already evaluated the effects of CBD on animal livers. They ran liver function tests that came back normal without any signs of damage, even if ALP was high.

You may be a bit cautious while giving CBD oil to dogs with liver diseases or problems. In addition, CBD may interfere with medicines metabolized in the liver.

Therefore, you should speak to your vet before giving your dog CBD oil. A medical professional is the best to tell you whether your pet should have CBD.

Apart from the above, we don’t have any recorded risks of CBD oil for dogs. We need more research to determine the long-term effects of CBD on animals.

What are the Side Effects of CBD Oil?

CBD oil may lead to side effects in some dogs. However, these are all minor effects and do not need immediate medical attention. Most of the symptoms resolve in a few hours after taking CBD as the effects fade off.

Here are the most common side effects your dog can experience:

Dry Mouth

CBD oil can make your dog look for water. Humans also experience dry mouth after having CBD or smoking marijuana. You can easily solve the issue by providing your dog with a bowl of water after giving CBD.


Some dogs can get drowsy after taking CBD, especially in large amounts. You may also find your pet disoriented and unable to walk properly.

A nap is an apt remedy in such cases. Also, start with a small serving size so that your dog can adjust to CBD gradually.


Many CBD oils contain additional ingredients or natural oils. These ingredients can irritate your dog’s gut and cause diarrhea. Your pet may also throw up after taking CBD.

The best approach is to use pure CBD oil for pets. Don’t go for any artificial flavoring or ingredients that put your dog’s health at risk.

You can also give your dog something to deal with the diarrhea. Switch to a different product and see what the results are.

A Drop in Blood Pressure

CBD oil can cause a temporary dip in your dog’s blood pressure. As a result, your furry friend may feel light-headed or nauseous.

Again, start with a small serving size so that your dog can get used to the new substance. Then increase the amount gradually to get desired results.

CBD Oil for Dogs: Tips for Safe Administration

Keeping a few things in mind can help your pets derive the benefits of CBD without discomfort:

Only Trace Amounts of THC Allowed

THC is toxic to dogs and can lead to poisoning. So, always choose CBD oil that contains only trace amounts of THC for the benefits.

Buy Hemp-Derived CBD Oil

CBD oil from hemp plants contains only negligible THC. As a result, you can give them to your pets without any risk.

Additionally, try to purchase full-spectrum CBD oil that contains other beneficial substances from hemp. Plus, avoid oils made solely from hemp seeds as they have less CBD.

Review the Label

Studying the label is necessary to find out what’s in your CBD oil. It will tell you the CBD and THC content and if there is anything else you should worry about.

In addition, check for a certificate of analysis for more assurance.

Final Thoughts

CBD oil is neither toxic nor will it kill your dog. You can try CBD for any healthy adult dog without any worries. However, buy CBD from hemp to avoid THC and gain complete peace of mind. Additionally, don’t forget to get your vet’s advice before you start CBD oil for your dog.
