CBD Dosing for Dogs: Choosing & Calculating the Right Dose

CBD Dosing for Dogs: Choosing & Calculating the Right Dose

In this article, I am going to walk you through how to calculate a dose of CBD for your dog.

 

My favorite CBD product is HempRx by Rx Vitamins for Pets. For small dogs, I recommend starting with the HempRx Soft Chewz or the HempRx oil. If your pup is 20 lb or larger, I recommend using the HempRx Forte to save money. This version is twice as concentrated with over twice the volume.

Products with high levels of CBD are expensive. 

 

For this reason, it is most economical to find the smallest dose that is effective for your dog. There are no industry wide established doses for dogs currently. As the cannabis market expands, more resources will be dedicated to research in optimal dosing for dogs.

 

Choosing A Dose

I start with 0.2 mg/kg twice daily and work up to 0.5 mg/kg or higher twice daily. The HempRx Soft Chewz for Small Dogs contains 1 mg per chew, while the HempRx Soft Chewz for Dogs contains 3 mg per chew. HempRx oil contains 0.5 mg per drop and the HempRx Forte contains 1 mg per drop.

 

It is safe to increase the dose past 0.5 mg/kg twice daily. Often for pain, seizures or severe inflammatory disease, I increase to 2-3 mg/kg twice daily. For reference, all of my animals are on 2 mg/kg or more twice daily. I definitely have the HempRx Forte in my fridge! If your dog tolerates CBD, the only downsides to a higher dose, is a higher cost.

Calculating a Dose

 

If you want to skip the calculations, I have a dosing chart here. However, if you want to calculate the dose yourself, here is how.

 

Step 1: Convert your pup’s weight from pounds (lbs) to kilograms (kg). You can do this by dividing the weight in pounds by 2.2. Let’s start with an 40 lb dog.

 

40lb (division sign) 2.2 = 18 kg

 

Step 2: Multiply the number of milligrams (mg) in the dose by the number of kilograms (kg). If the dose is 0.2 mg/kg, you would multiply 18 kg x 0.2 mg to get 3.6 mg. I would round this up to 4 mg.

 

0.2 mg x 18 kg = 3.6 mg per dose, round to 4 mg per dose

 

Step 3: Use the concentration of the CBD product you are using to calculate the volume of oil you should administer. Depending on the product you are using, this is easier said than done. If you are using HempRx or HempRx Forte, it’s REALLY simple! HempRx has 0.5 mg per drop. HempRx Forte has 1 mg per drop. For example if you need to give your pup 4 mg of CBD twice daily. You could use 8 drops of the HempRx or 4 drops of the HempRx Forte twice daily.

 

If you are using another product, you need to know how many milligrams (mg) of CBD is in each milliliter (mL) of oil. Unfortunately there are a few companies that refuse to disclose this information. It is impossible to know if the dose you are using is therapeutic. For this reason, I don’t recommend these products.

 

Once you know how many milligrams of CBD are in each milliliter (ml) you can calculate the dose volume. For example, HempRx has 15 mg of CBD per milliliter (mL) of oil. If I have calculated my dose to 4 mg of CBD twice daily, I simply divide 4 by 15 to get the number of milliliters of oil I need to give my kitty.

 

HempRx has 15 mg/ml of CBD Dose of CBD is 4 mg twice daily 4 mg (divided by sign) 15 mg = 0.266 ml Dosing past one tenth of a milliliter is difficult. Don’t do it!

 

I would round 0.266 mls to 0.3 mls. For this volume, you could use a 1 milliliter syringe and draw back to 0.3 mL mark. If you prefer to use the dropper in the bottle, you could estimate a third of the dropper. This assumes the dropper holds 1 mL of liquid. For reference 1 milliliter (mL) is equal to a cc.

 

Is your head spinning with numbers and units of measurements yet? Feel free to post questions in the comments below!

 

Sending you and your pet all of my love,

I have started my 13 yo labradoodle on hempRx forte cbd oil. She was diagnosed with Cushings disease in early September, started on Vetoryl, and has panting and weakness /discomfort in her hind quarters. She weighs 36 lbs and I started her on 4 drops 2 times a day one week ago. So far i haven’t noticed an improvement in her discomfort and wondered how long I should wait until increasing the drops. Also when I do, should I gradually increase by 1 drop a day,-so 5 drops in am and 4 in the pm.? Thank you for your guidance.

Hi Joanne, I am so sorry to hear that your labradoodle is panting and uncomfortable. I know how difficult this must be for you both! I think a week is a fair trial to see if your girl will respond to the low end of the dose range. You can certainly try gradually increasing her dose until you find the right amount for her. It is safe to increase by 1 drop twice daily, every other day until you find the lowest effective dose. It is also ok to start increasing by 1 drop each day if you prefer. If… Read more »

My dog has had wobblers surgery and a spinal stroke. He is 145 pounds and your dosing chart does not cover that weight. He walks about 85% normal and is 7 yrs old this month. I feel he could benefit from your products but am not sure which one. I know he has some inflammation and pain. I am not sure because of his size and the amounts he would need if I could ever afford it but if you have some thoughts that would be great. Thank you,

We adopted our Pit Bull/ Mastif mix 8 months ago-80 lbs. He has serious vision issues and is partially blind in one eye. He is anywhere from 6 to 8 yrs old. 3 months after we had him he got Leptospirosis and was in2 different hospitals for 7 days- serious liver, kidney issues. He survived but has had periodic behavior issues since then. A day care facility which we had to remove him from thought he had a seizure after an incident of snapping at another dog. He has also been aggressive towards dog walkers who he was fine with… Read more »

I have a bottle of CBD Hemp oil 2000mg/30 ml. I was told there is 66mg per ml of CBD. I have a dog who has severe anxiety when going outside and worse when he goes to the groomer or the vet. How many drops should I give him a day? Thank you!

Regarding dosage… Yes, my head is spinning a bit!! To be sure I have this correct… I just purchased oil that says it has 3mg CBD per serving and the serving size is 15 drops, so that would be 1mg per every 5 drops. My dog weighs about 80 lbs. If I double you 40 lb example above, I would be giving him 8mg, so 40 drops? That seems excessive. I should add that this CBD was purchased at the grocery store for human consumption, which would assume at least 150 lbs, I would suppose. Please help if you have… Read more »

Hi there! Thank you for the helpful information on dosage. Do you think my 10 year old Yorkie who developed a murmur in the past 6 months, would benefit from having CBD oil? I hear it’s good for the heart for anti-inflammatory properties.

I’m trying to figure this out and any help would be amazing! My German Shepherd has seizures and was told by my vet that cbd might help. Trying to figure out how much to give him. He is a bit over 70lbs (32kg) and I got a 30ml bottle of 1000mg. The place I bought it from said 3-4 drops 2 times a day but that seems like a lot?

We have a 12 1/2 year old 4lb Yorkie. She has issues with her hide hips, knees and a disk issue towards her back half. I want to start her on CBD. My question is: she had been on prednisone .5 mg for a year now. Once I start the CBD should I stop the prednisone? We live in East TN and I have not asked our vet yet, but don’t expect him to agree with CBD. This area is very western medicine. Thank you for your opinion.

Hi
On another reply, you state that for an 80 lb. dog, it’s ok to give 9-18mg of CBD. I use the 250mg strength and I tend to measure by drops. How many drops would that be? (I’m dosing her 2x a day)
Thanks!

I just bought a bottle of HempRX oil, and am wondering how to administer it. For my (55 lb) dog, I will to start out with 10 drops, 2x a day. Any suggestions on how to administer it? I tried putting some drops in a pill pouch, but he spat that out. My fear is that I’ll put it on food, and he’ll reject it (and I would have wasted the oil and the food). Typically I would inject something like this (he takes a prescribed liquid NSAID) between his cheek and gums, but trying to get the dosage from… Read more »

Hi, I have a 7 year old English Golden Retriever with arthritis in his elbow and hip. He’s been on CBD oil, but I want to make sure that I am giving him the correct dose. He weighs ~90 pounds. We give him NuLeaf Naturals CBD oil 1450mg/30ml, which has 2.4 mg for 1 drop. Their pet bottle says if your pet weighs over 75lbs to give 8+ drops 1-2 times a day and the directions for use say 2-3 drops per 20lbs. So, is it appropriate to give our dog 9 drops two times a day? Thanks for your… Read more »

I have a 5lb Chihuahua who is 15, slowed down and tail is tucked – confused by all the options out there – some say 125mg, to 750mg etc – how do I pick the right strength and can you over medicate ? How long on average does it take to see results for pain/aging in tiny dogs.
Are there any risks or side effects ?

Dr. Angie, Thank you for this great article! I am looking for some information on using CBD as a way to treat my dog’s situational anxiety during thunderstorms. I am having some difficulty finding if CBD is something I’d give him at the onset of his anxiety or if it is something I’d give him daily in hopes of helping with the situations that make him anxious. I’m not looking for him to be extra mellow or tired, just trying to find a way to calm him during storms. Please let me know how you would recommend dosing CBD for… Read more »
