If you choose to give your dog CBD oil, aim at 0.1- 0.2 mg per kg weight, but you can always up the dosage when necessaary. Still, many factors other than weight determine the right CBD dosage for anxiety, including the dog’s previous exposure to CBD oil and the purpose of the CBD oil.

A dosage of 0.1- 0.2 mg of CBD oil per kg weight for a dog might be enough for your dog, especially when starting on the CBD regime. You may choose to up the CBD dosages depending on how the dog responds to the cannabinoid. Still, many factors like the dog’s previous exposure to CBD oil and the purpose of the cannabinoid determine how much CBD oil you can give the canine friend. Here is all you need to know about how much CBD oil your dog needs for anxiety.

CBD Oil for Anxiety in Dogs- What Studies Say

According to García-Gutiérrez et al. (2020), CBD oil may be good for anxiety, stress, and depression. Besides, Silote et al. (2019) found that CBD oil may be better than the conventional antidepressants, suggesting that the cannabinoid may be great for fighting depression. What’s more, Vučković et al. (2018) examined various CBD studies from 1975 through March 2018 and reported that the cannabinoid might be great for chronic pains, including neuropathic, cancer, and fibromyalgia pains. Since chronic pain might cause anxiety, fighting pain may result in reduced anxiety. These confirm that CBD oil may be therapeutic (Watt & Karl, 2017). However, more research is needed to offer enough scientific evidence to prove that CBD oil might be good for the claimed benefits.

There Are No Controlled Studies for CBD Oil and Anxiety in Dogs

Although many studies claim that CBD oil might be good for anxiety, there is no controlled research on the cannabinoid for anxiety in dogs. Generally, CBD studies are limited, with only a few research papers on the role of CBD oil for anxiety in dogs. The lack of scientific studies to prove the effectiveness of CBD oil for anxiety in dogs leaves doubt as to whether administering the cannabinoid might result in positive effects.

CBD Oil for Anxiety in Dogs- How Much Should You Give the Dog?

Many people starting the cannabinoid profile on dogs would like to know how much CBD they need to give their dogs. Unfortunately, the FDA does not monitor or control the production of non-prescription CBD oil, including CBD oil for dogs. There is no dosage recommendation for CBD oil, even when administering it to your dog. Generally, 0.1- 0.2 mg per kg weight of the dog is ideal. Still, you may want to up the dosage as time goes by, specifically when you are sure that the dog needs more and when you deem it fit. Meanwhile, the following major factors affect how much CBD oil you need to give your dog for anxiety or other health benefits.

The Weight of Your Dog

The dog’s weight determines how much CBD oil you can offer it. The 0.1- 0.2 mg CBD per kg weight of the dog clearly shows that your dog’s weight is critical as far as offering CBD oil is concerned. Generally, weight is directly proportional to the amount of CBD oil you can offer. Heavy dogs need more CBD oil than smaller dogs, keeping all factors constant.

The Previous Exposure of CBD Oil to the Dogs

The amount of CBD oil you want to offer your dog is directly linked to the dog’s previous exposure to the cannabinoid. The more a dog takes CBD oil and get used to it, the more the body gets used to high dosages, especially if you up the dosage consistently. Therefore, consider the animal’s history before deciding how much CBD oil the dog can take. If the dog has been taking CBD oil in the past, his body is likely used to the cannabinoid, and accommodates higher amounts of the cannabinoid.

The Potency of the CBD Oil

Potency refers to the CBD concentration per unit volume. It is calculated by finding the quotient of CBD oil and the total volume of the content. Its ranges from as small as 2 mg/ml and as high as 200 mg/ml. How much CBD is present in a unit volume or 1 ml of the CBD oil determines how much CBD you can give the dog. Of course, the higher the potency, the more increased chances of getting CBD effects in the dog fast. Therefore, you might have to administer only a little of the cannabinoid. Confirm the potency by scanning the QR codes on your product’s label to access the third-party laboratory test results.

Quality of the CBD Oil

Other than CBD potency, the quality of the cannabinoid is equally important in gauging how much cannabinoid the dog needs for anxiety. Like potency, good quality increases the effectiveness of CBD oil. The reverse is also true, where low-quality CBD oils with low CBD potency may have to be administered in high amounts for the dog to benefit from the anxiety-related effects of the cannabinoid. Therefore, you should focus on quality as you buy CBD oil for your dog. You can be assured of quality products by buying from reputable brands.


How much CBD oil you need to give your dog for anxiety depends on many factors. Generally, the weight and size of the dog seem to be the major play, especially because you only need 0.1- 0.2 mg CBD per kg weight of the dog. Still, the dog’s previous exposure to CBD oil and the potency/ quality of CBD oil determines how much CBD oil you want to give your dog.
