How Much CBD Oil Should I Give My Dog?

CBD oil has gained mainstream popularity in recent years, thanks to its potential for combating both moderate and serious ailments. Research and anecdotal evidence have revealed that these benefits may extend beyond humans and be able to help our pets as well. This is exciting news for dog owners everywhere, especially those with pets struggling with disease, aging and anxiety. If you’re a pet owner considering CBD treatment, you may find yourself wondering: exactly how much CBD oil should I give my dog?

CBD oil dosage basics

Before we answer how much CBD oil should I give my dog?, it’s important to start with the basics of CBD oil dosage. 

CBD oils are administered in drops. The exact number of drops that equate to your dog’s appropriate dose will vary from product to product, since the concentration of CBD varies in each.

For example, if you have two bottles of the same size, and one contains 150mg CBD while the other contains 300mg CBD, the second bottle will be more concentrated. This means that one drop from the 150mg bottle may only contain 0.5mg CBD, while a drop from the 300mg bottle may contain 1.0mg CBD. It’s important to keep CBD concentrations in mind when figuring out how much CBD oil should I give my dog?

Some higher quality CBD oils will include markings on the dropper that let you know exactly how much CBD you’re administering. This makes it much easier to give the appropriate amount of CBD oil to your dog.

Factors to consider when giving CBD to your dog

The two most important factors to consider when determining how much CBD oil should I give my dog are your pet’s weight and the condition you’re aiming to resolve.


Larger dogs will require a higher dose of CBD to achieve beneficial results. An amount that’s very beneficial to a Great Dane may be a bit too much for a Chihuahua. The same can be said for adult dogs and puppies. 

A general rule of thumb to start with is to multiply your dog’s weight by 0.25. This will give you an estimate of your dog’s ideal dose of CBD, which you can then add to or subtract from depending on the results. 

For example:

  • For an 8-pound dog: 8 lbs x 0.25 = 2mg CBD per day
  • For a 24-pound dog: 24 lbs x 0.25 = 6mg CBD per day 
  • For a 60-pound dog: 60 lbs x 0.25 = 15 mg CBD per day


The ailments and medical conditions that your dog is experiencing may also play a role in determining how much CBD oil should I give my dog? 

CBD can potentially help your pet with a wide variety of conditions, including:

For more serious and debilitating conditions like cancer, epilepsy, and inflammatory disorders, a higher dose of CBD may be necessary to achieve desired results.

For milder symptoms, or for a boost in overall well-being for a generally healthy dog, smaller doses are typically recommended. 

How much CBD oil should I give my dog: suggested dosage

The following ranges are estimates for your dog’s ideal CBD dose based on his/her size. It’s best to use caution and start with the smallest recommended dose, gradually increasing the amount until you notice symptoms improving. 

  • 10 pounds: 1 mg – 5 mg
  • 20 pounds: 2 mg – 10 mg
  • 30 pounds: 3 mg – 15 mg
  • 40 pounds: 4 mg – 20 mg
  • 50 pounds: 5 mg – 25 mg
  • 60 pounds: 6 mg – 30 mg
  • 70 pounds: 7 mg – 35 mg
  • 80 pounds: 8 mg – 40 mg
  • 90 pounds: 9 mg – 45 mg

CBD takes about 30 minutes to start working when ingested orally, and you likely won’t notice significant changes in your dog’s behavior right away. Still, it’s important to start with low doses, and increase the dose by about 0.25mg every few days if you feel it’s necessary. 

If you’re still not sure about how much CBD oil should I give my dog, your veterinarian may be able to make a more personalized recommendation. 

Can I give too much CBD oil to my dog?

Finding the right CBD dosage for your dog will take some trial and error. Fortunately, there’s no way you can give your dog an overdose of CBD.

CBD is a very safe and forgiving medicine. Not only is it completely non-toxic and incapable of causing an overdose – it also has not been found to produce any serious, harmful, or long-term side effects.

If your dog seems a bit sleepier or more drowsy than usual, this may be a sign that you’re giving him/her a little too much CBD. Drowsiness can usually be resolved by reducing the amount of CBD you give to your dog.

How should I give CBD oil to my dog?

CBD oil is best absorbed when it’s administered directly into the mouth, ideally under the tongue. However, it can be tricky to get some dogs to cooperate and take the medicine properly.

If you’re having trouble getting your dog to take CBD oil, you can try rewarding him/her with a treat afterwards. You could also try dropping the CBD oil directly onto something, such as a treat or a spoonful of peanut butter, and giving that to your dog. After a few days, your dog may get used to the routine of taking CBD oil and may even begin to enjoy it. 

CBD Oil & Dogs: Final Thoughts

Before beginning CBD or any other treatment for your dog, it’s important to consult your veterinarian. All dogs are unique, and your vet may be able to make a more individualized recommendation on CBD oil dosage and use for your pet. 

Finding the right CBD oil for your dog can be tricky, as many CBD oils available on the market contain THC or other compounds that could potentially harm your pet. To make sure your dog is getting the most benefit out of CBD oil, we recommend finding one that:

  • Is extracted from legally harvested hemp
  • Contains no more than 0.3% THC
  • Contains only clean, organic ingredients
  • Was not extracted using harsh solvents or chemicals
