How much cbd oil for my 65 pound dog

What Is The Recommended CBD Dosage For Dogs?

You may be wondering what is the recommended CBD dosage for dogs? While there are no official guidelines yet, you can get helpful dosage information from scientific studies, CBD manufacturers, and veterinarians.

This lack of information is because hemp-derived products like CBD were only removed as Schedule I drugs in 2018. Due to the 2018 Farm Bill, CBD is now legal as a hemp product as long as it complies with state and federal laws.

Since that time, CBD has become an incredibly popular supplement both for humans and dogs.

By the way, make sure to check out my list of the best CBD oil for dogs. Additionally, I also made a list of dog CBD treats for anxiety, mobility, or joint issues.

However, at this time, there’s only limited studies that explore how much CBD to give your dog and its benefits.

In this article, I’ll be sharing information from various sources on the proper CBD dosage for dogs.

What Manufacturers Recommend for CBD Dosage for Dogs

While there are many CBD manufacturers, I will provide a few dosage recommendations from popular brands.


Recommendation: They recommend a CBD dosage between 0.25 mg (regular dose) to 0.5 mg (strong dose) per pound of body weight.

They recommend their regular dose for the following uses: boosting immune function, daily health and wellness, stimulating appetite, allergies, minor anxiety and stress, minor skin issues, old age, allergies, minor aches and pains, minor anxiety and stress, moderate joint inflammation and arthritis, and digestive issues and nausea.

They recommend their strong dose for the following uses: mobility issues, severe arthritis and joint inflammation, chronic pain, cancer-related symptoms, epileptic seizures, severe anxiety, tumors, vomiting, and extreme nausea.

As far as dosing frequency, they recommend the following:

  • Every 8 hours (or as needed) for inflammation and pain
  • 30 minutes prior to an event (such as thunder, fireworks, etc.) to help with anxiety
  • 1-2 per day for all other uses

Holistapet sells organic, plant-based CBD products.

Honest Paws

Recommendation: They recommend generally to use .25mg of CBD per pound of body weight as an effective amount for dogs.

Note: they get a little more specific on their FAQ page where they recommend 5 mg/day for dogs up to 25 lbs, 10 mg/day for dogs between 25 and 50 lbs, and 15 mg/day for dogs over 50 lbs.

However, they acknowledge that each pet is unique and may require more or less CBD.

As a result, they recommend beginning with half of the recommended dose and increasing slowly.

Honest Paws sells dog CBD treats and oils in pet and drug stores across the U.S.

Austin and Kat

Recommendation: They provide a rule of thumb to begin with 1-2 mg for every 10 lb of body weight (.1 mg – .2 mg per lb of weight).

They state that this recommendation is just a guide to start off, but then for you to adjust at your discretion either more or less.

They also mention that some dogs will only need 1 serving per day, while other may need 2 ore more depending on the condition and severity.

Austin and Kat sells CBD for dogs that is hemp derived and broad spectrum.

What Studies Say About CBD Dosage for Dogs

While there is no conclusive answer as to how much CBD you should give your dog, you can look at dosages in recent studies.

There are a handful of studies published within the last two years that discuss the safety and efficacy of different dosages.

However, these studies still caution that more research needs to be done.

Two different studies on canine osteoarthritis found that giving dogs 2 mg of CBD oil per kg of body weight twice daily reduced arthritis-related pain and increased mobility.

Pro tip for lbs: 2 mg of CBD per kg of weight should equal roughly .9 mg of CBD per lb of body weight (Calculations: Starting with 2 mg of CBD per kg of body weight, we first need to convert kg to lbs. Since 1 kg=2.20462 lbs, it now becomes 2 mg of CBD per 2.20462 lbs. Then we multiple 1 lb times 2 mg/2.20462 lbs, which equals .907 mg per pound of body weight).

One of these studies, published in July of 2018, found that CBD’s effect on dog’s bodies only lasted for about four to five hours.

Due to this limited effect, researchers concluded that a dose of 2 mg per kg of body weight should be given every 12 hours.

The second study was published more recently (in March of 2020) and it observed that most dogs benefited from a dose of about 1-2 mg of CBD per kg of body weight when given every 12 hours. However, researchers noted that the necessary dosage varied by dog. While some needed as little as 0.3 mg per kg of body weight, others required as much as 4.12 mg.

As mentioned, these two studies focused on CBD’s effects on canine osteoarthritis. Unfortunately, there are not many studies available about effective dosages of CBD for other ailments.

Interestingly, there is anecdotal evidence from veterinarians suggesting that low doses and high doses have different effects on dogs and address different ailments.

Such evidence was discussed in a chapter titled “Cannabis in Veterinary Medicine: Cannabinoid Therapies for Animals” in Neutraceuticals in Veterinary Medicine.

At this point, there is not enough research available to determine how much CBD to give to treat each ailment.

What Veterinarians Recommend for CBD Dosage for Dogs

Recommendation: One specific veterinarian recommends 1 mg of CBD per 10 pounds of body weight twice daily.

In some states, vets can face license suspensions and penalties if advising clients on CBD. As a result, it can be difficult to find recommendations online from vets on the proper CBD dosage.

However, I did find one recommendation in my research:

In an article by Consumer Reports, Judy Morgan, D.V.M., recommended giving 1 mg of CBD per 10 pounds of body weight twice daily. For a 40 lb dog, you would give 4 mg twice per day for a daily total of 8 mg of CBD.

If I find any more recommendations, I will list them here. In the meantime, check with your veterinarian on their recommendations.

How to Determine Dosage for Your Dog

If you’re interested in giving CBD to your dog, how exactly do you determine the dosage? It’s going to take some trial and error.

The most common advice is to start small and increase your dog’s dosage until you see the results you’re looking for. By the way, I also wrote an article on how long CBD dog treats take to work.

If you’re hoping to treat arthritis, then you may want to follow the example of the two studies mentioned earlier.

In those studies, they gave 2 mg of CBD per kg of body weight twice daily. However, I would not recommend starting at such high of a dose.

Whatever form you’re giving CBD, look at the packaging to see the serving size and proper dosages.

It should tell you how many mg of CBD are in each serving and the recommended amount of ml depending on the weight of your dog.

You can also listen to veterinarians if they are willing to share their recommendations with you.

As you can see, Honest Paws, Holistapet, Austin and Kat and veterinarian Judy Morgan recommend significantly less than the amounts suggested in the arthritis studies.

Side Effects

It’s important to talk about potential side effects of CBD.

According to “Cannabis in Veterinary Medicine: Cannabinoid Therapies for Animals,” the most common side effects of CBD are mild: diarrhea and sedation.

All of the studies mentioned earlier have also noted a rise in an enzyme called alkaline phosphatase (ALP), but did not seem concerned that ALP levels would get too high.

These side effects can occur even at low dosages. As a result, you should monitor your dog and determine whether or not CBD is causing any discomfort.

I have not read anything about any severe or life-threatening events.

However, I have read that CBD may interfere with some medications that your dog is taking.

As always, talk to your vet before giving anything new to your dog.

Choosing the Proper Strength of CBD Oil for Your Dog

You may have noticed that CBD oil comes in different strengths: 300 mg, 500 mg, 600 mg, 1000 mg, 2000 mg, and everything in between.

But what do all of these numbers actually mean? These numbers indicate the amount of CBD inside the bottle.

CBD is not the only ingredient. Instead, manufacturers place the CBD into a carrier oil, which makes it easier to ingest.

Most makers sell CBD oil in 30 mL bottles (meaning you get 30 mL of total liquid, not 30 mL of CBD).

However, a 30 mL bottle with 1000 mg has more CBD inside it than a 30 mL bottle with 300 mg.

If you look on the back of the bottle, it will tell you how much CBD is in one serving (one serving is typically equal to 1 mL).

A bottle labeled 300 mg has about 10 mg of CBD per 1 mL serving, whereas a bottle labeled as 1000 mg has about 33 mg of CBD per 1 mL serving.

Higher strengths are typically more expensive, so you may be tempted to opt for a lower strength. However, depending on the dosage your dog needs, you may not actually save any money this way.

For instance, let’s say that we’re treating a 75 lb (34kg) dog for arthritis using CBD oil. If we follow the dosage recommended by the studies mentioned earlier (2 mg per kg), then the dog should be getting 68 mg of CBD every 12 hours, or 136 mg per day.

Remember, a bottle labeled 300 mg has 10 mg of CBD per 1 mL serving. This means our 75 lb dog would need to get about 14 mL a day. Since the bottle only has 30 servings, you’ve just used half of it in one day!

In this case, you’d be much better off purchasing CBD oil with a higher strength, like 2000 mg.

Of course, as the studies explained, your dog may need more or less than 2 mg per kg of body weight.

As we mentioned earlier, you will have to go through some trial and error to determine exactly how much CBD works for your dog.

Still, it’s good to have some sort of guideline for choosing a strength. If you have a larger dog, you’ll likely want to opt for a higher strength.

Do I Have to Buy CBD Products Marketed For Dogs?

If you’ve been shopping around for CBD products, you may have noticed many of them are marketed toward pets. But they’re often more expensive and don’t offer high strengths.

So, do you really need to buy CBD made for dogs? The answer is no.

CBD oil is typically made of a carrier oil, the CBD, and natural or artificial flavoring.

When purchasing CBD for your dog, choose an unflavored variety and check the ingredients just to be safe. You can Google anything you are unfamiliar with.

If you choose a product marketed for dogs, then flavorings are normally less of an issue.

So we’ve talked about oil, but what about other products? Obviously, you should not give chews made for humans to dogs.

They may contain harmful artificial sweeteners. If you’re choosing an edible variety of CBD, then it would be best to choose something made for dogs.

As far as capsules go, these are usually safe to give to your dog. Most capsules have the carrier oil and CBD inside, and the capsule itself is made from gelatin. Again, you can always look up any ingredient you are unfamiliar with to be sure it is safe.

All in all, the only “human” CBD products you shouldn’t be giving your dog are flavored oils and edible products like gummies. Unflavored oils and capsules are a safe bet.

Should I Buy THC-Free CBD Oil?

You may have noticed that you can buy THC-free CBD oil.

CBD oil has less than 0.3% THC in it to begin with, so there is not enough THC in the product to have a negative effect on your dog.

You can certainly buy a THC-free oil if you prefer, but it is not necessary.


Determining the proper CBD dosage for dogs will involve some trial and error. Most recommendations online say to start low and increase until you see results.

The USDA previously classified hemp products like CBD as Schedule I drugs until 2018. As a result, there hasn’t been much research done to determine what dose of CBD you should give your dog.

Luckily, most dogs will not experience side effects from CBD, which are pretty mild (diarrhea and sedation).

Don’t forget to check out my list of the best CBD oil for dogs or list of dog CBD treats for anxiety, mobility, or joint issues.

CBD Dosage for Dogs: How Much Should I Give My Dog?

Still not sure how to figure out how much CBD you should give your dog?

As a team of CBD aficionados and pet lovers obsessed with their puppies, we’ll be more than happy to help you find the right dose of cannabidiol (CBD) for your furry friend.

And if you’re here for the first time wondering why on earth we would even consider giving CBD to a dog, here’s a quick reminder:

Dogs and cats have an endocannabinoid system, too – just like humans.

That being said, CBD, a powerful compound found in the cannabis plant, shows great potential as an alternative form of treatment for dogs, cats, and other pets that are struggling with a range of health conditions.

Finding the right dose of CBD can be tricky, as there are plenty of factors that can determine the effects it will have on your dog or cat.

We’ll cover all you need to know about dosing CBD for pets and walk you through the best dosage guidelines for different forms of CBD consumption.

Things to Consider Before Giving CBD to Your Dog

Figuring out the right CBD oil dosage for your dog can be a hard nut to crack, especially for pet owners who are just getting started with CBD for pets.

We’ll use dogs as an example because that’s where we have the most experience; however, the same guidelines apply to cats and other (mammalian) pets.

There are three essential factors to take into consideration prior to buying CBD for your pet:

1. Consumption Method

One of the factors that determine how much CBD you will give your dog is the type of product you use, along with the brand you’re using.

CBD products for dogs come in 4 main forms:

  • CBD and Hemp oil
  • Capsules
  • Topical rubs
  • Treats (edibles)

CBD and hemp oils are by far the best option for dogs as they offer the highest bioavailability. This means that less CBD is needed to produce the effects you want.

However, not every dog will like the distinct taste of CBD oil, so if that’s the case, CBD dog treats would do the trick.

Not only will they taste better – imagine flavors like Chicken & Bacon or Roasted Duck – but they also come with a fixed CBD dose.

This way, you know exactly how much CBD you’re giving your dog.

However, there’s one downside to using CBD dog treats:

They’re much slower.

The cannabinoids in the treats need to pass through your dog’s digestive system to make it into the bloodstream. This means the effects will have a slower onset time than oils and your dog may receive less CBD overall.

The same applies to CBD capsules for dogs, but capsules just aren’t as enjoyable for the dogs as the treats.

The benefits of capsules, however, are that they have a higher fixed dose, and are more reliable in the level of effects they’ll produce.

2. Your Pet’s Size

It’s no surprise that the CBD dosage for vary depending on your dog’s size. But how do I determine what dose is correct?

The general rule is that larger dogs need more CBD to experience the effects than smaller puppies. Some brands provide their own dosage charts based on the weight of your dog. This makes dosing easier from the start.

Keep reading to learn specific dosage guidelines depending on the size of your dog.

3. The Severity of Your Dog’s Condition

Finally, keep in mind that your dog’s condition can also affect how much CBD should you give him/her.

The more severe the condition, the higher the dose they’ll likely need to alleviate the discomfort.

If you want to supplement your dog with CBD oil, low doses will usually suffice, but for anxiety or joint pain, you’ll need to increase the dosage and observe the effects until you hit the sweet spot.

General CBD Dosage Guidelines For Dogs

For general supplementation or mild conditions, the exact amount of drops in a CBD oil to meet the estimated dosage will vary between products.

In general, 2-4 drops taken two to four times a day are recommended.

You can also adjust the dosage, based on the size of your pet and his/her condition we’ve just talked about.

A CBD capsule, in turn, will contain between 5-20 mg of CBD each. The dose of encapsulated CBD is around 1 tablet taken once or twice per day.

As for pet treats, they will vary in concentrations of CBD.

Always check if your CBD company provides dosing instructions at the back of the package. If it does, it’s best to follow the instructions.

Actually, regardless of the product you use, we always recommend following the dosage instructions that came with it and based on this, adjust the dose as needed.

We recommend starting at the low end of the dose, and increasing gradually once you know how your dog will respond.

How to Figure Out How Much CBD You Should Give to Your Dog By Size

To make it easy for you, we’ll break down exactly how to choose the right dose for your dog based on their size (measured in weight).

Some people prefer to use a very small dose, no matter what size their dog is and working up from there.

A rough starting dose to do this is 1 mg.

This allows you to gradually work your way up the optimal dose without wasting too much CBD oil in the process.

Even large dogs are about ⅓ the size of average humans, so considering that in humans, the jumping-off point is around 1-3 mg, the above figure makes sense.

To begin with, let’s discuss how much CBD you should give to your dog, based on relative weight.

1. Small (2-15 lbs)

Extra small dogs will need the least amount of CBD, which may sound relieving at first.

But there’s a catch.

Tiny dogs have a super-fast metabolism!

You will need to increase the frequency of CBD administration to 3-4 doses per day, instead of 1 or 2 with larger dogs.

If your dog is suffering from pain, the starting CBD dose of 1 mg may be enough for the beginning.

For behavioral conditions like dogs with anxiety, we recommend measuring out ½ mg worth of oil and adding a couple of drops if you don’t see any improvement for the next 3-5 days of use.

As for a routine, it’s best to start by administering CBD twice daily.

Each time you want to increase the dosage, you can do it in 2 mg increments until your dog finds some relief.

Nevertheless, try not to exceed 15 mg CBD doses in extra small dogs.

Remember that these are all relative figures, and should not be taken as medical advice or as a veterinary recommendation.

2. Medium-Small (15 – 30 lbs)

Having done in-depth research on different CBD dosages for medium dogs, we’ve noticed that many people achieve success with a 2 mg dose, and increasing by 3 mg until they get some results

This data refers to dogs suffering from pain and arthritis.

For psychological conditions and poor appetite, try using half the dose above (1 mg of CBD).

For most medium sized dogs this should do the trick.

Dog owners who want to help their friends with anxiety are recommended to increase doses by no more than 2 mg, keeping mind that they shouldn’t exceed 2 doses per day.

The maximum dose of CBD for a dog of this size is about 20 mg per day.

3. Medium-Large

Like we said before, larger dogs require more CBD to experience the desired effects.

What’s an appropriate initial dose of CBD for dogs with general pain?

It’s generally believed that a 1-3 mg dose of CBD is a good starting point, depending on the level of the pain.

If you’re not seeing the results you want to try increasing by 3 mg.

For behavioral conditions (lack of focus), psychological disorders (panic, anxiety), and poor appetite, the recommended initial dose is 1 mg twice a day.

Make sure to keep a watchful eye on your dog’s behavior to notice if the effects of CBD are kicking in.

If not, increase the dose by no more than 2 mg.

The maximum dose for CBD for a dog of this size is about 30 mg per day.

4. Large (60 – 150 lbs)

Owners of large dogs should follow the same general recommendations as for medium-large dogs.

With very large dogs, you can expect to have a much higher dose, however, it’s best to work your way up slowly by 3 mg per dose until you find signs of relief.

Getting The Dose Right With Different CBD Products

So now that you know the mg of CBD you should use on your dog or cat, you may be wondering how this applies to different CBD products.

After all, not all CBD products contain the same concentration of CBD.

Calculating the right dose of Cannabidiol may look like a cutscene from the “Beautiful Mind” movie, so we’ll help you out a bit.

Below, we share specific details about CBD dosing for dogs using common strengths and volumes.

1. CBD or Hemp Oil

CBD oil for dogs typically comes in 150, 300, and 600 mg bottles. Here are the basic dosage tips for this kind of CBD.

Here’s a quick reference to how the different CBD concentrations work out in drops.

What dose of CBD oil do I use for my dog?

If you are wondering when and how to use CBD oil for your dog, you’re not alone! Luckily we have some controlled research to help guide us in our decision for dosing hemp and CBD products for dogs. (1, 2)

Based on the latest research about CBD use in dogs, we know that 1-2 milligrams per kilogram CBD is a good starting point for most dogs. Now, use the dog’s weight to determine how that might look:

Example: 45 pound border collie with joint pain. Divide 45lb by 2.2 and you get 20.45kg. 20-40milligrams of CBD would be appropriate.

To avoid conversion, you can use 0.45-0.9 milligrams per pound CBD. Multiply by the dogs weight (in this case, 45lb) and you will also get 20-40 milligrams of CBD per dose.

Importantly, you must know how many milligrams per milliliter (or bottle) is in your pet’s CBD product. Reputable companies should have mg/ml or total bottle mg count and volume right on the label. At VetCS, we make easy dosing instructions available on every bottle. Week 1 dose is 2mg/kg and Week 2+ dose is 1mg/kg.

Going back to the border collie, if you bought a 1200mg bottle of CBD oil and it’s total volume is 30ml, then that formula is 40mg/ml. We wanted 20-40mg CBD per dose, so you would give 0.5-1ml twice daily to help the joint pain. We often recommend the higher dosing amount (1ml in this case) for moderate to severe pain.

How often should you dose CBD? Research has shown that the half-life range in dogs given CBD oil is 3-4.2 hours. (3,4) That means dosing twice daily is best for your pup. However, when using CBD to relieve anxiety (car trips, thunderstorms, etc), simply dosing 30 minutes before an anticipated stressful event is all you need to give. For other conditions such as mobility issues, seizures, and decreased appetite, twice daily dosing is recommended to best help your dog.

Remember that dosing is dependent on condition as well. Dogs with anxiety typically respond to much lower doses of CBD (0.25-0.5mg/kg) than dogs continuing to have seizures despite numerous pharmaceuticals. In these instances, talking to your veterinarian is best with pets that are already on medications. Alternatively, our team at VetCS can help you determine dosing, just contact us by phone, email, or chat!
