Cannabis for Pets: Beyond the Basics

cannabis pets beyond basics boulderholisticvet blog post

As legislation for medical and recreational marijuana sweeps the country, the application of cannabis for dogs and cats has become a point of focus for pet parents and the veterinary community. This article, will cover more detailed information about cannabis and it’s medicinal use in dogs and cats. For a more basic understanding of cannabis for pets, check out my articles for cats here and dogs here.

Endocannabinoid System

Are you ready to geek out? There is a whole system in both human and animal bodies known as the endocannabinoid system. This system is located in the nervous system (brain, spinal cord and nerves) and is made up of receptors. These receptors bind THC and CBD among other components of the cannabis plant. This system influences many processes related to pain, mood, immune function and much more. As this system is studied we will be able to understand why cannabis works so well for certain conditions. We may also expand the scope of what cannabis may treat.

There is still much to learn about the endocannabinoid system in people and pets. However, we do know that dogs have many more THC receptors (CB-1) in their brains compared with people. This is why they are more sensitive to effects of THC compared with their human counterpart. In other words, the amount needed for a person to become comfortably euphoric (high) can cause extreme high with negative effects of the nervous system in dogs.

As cannabis is bred to have more and more THC, veterinarians see more and more toxicity in dogs. Some of these cases can be deadly and cause much suffering for patients. If your veterinarian is not open to discuss cannabis (even without THC), this is most likely the reason. We all took an oath to first do no harm. As cannabis becomes legal across the US, veterinarians will have more opportunities to learn about the difference between hemp and marijuana.

Entourage

You may have heard of the ‘entourage effect’ when it comes to medicinal marijuana. This simply refers to the synergistic effect of THC on CBD. In other words, the presence of THC is thought to increase the medicinal effect of CBD. Many experts in the field recommend only products with THC due to this concept.

While this synergy may be beneficial for people, it is important that we consider our animal’s comfort when using cannabis. When a person consumes cannabis, they can report how they feel and titrate the dose independently. Our animal companions don’t have this ability. THC can cause paranoia, hallucinations and anxiety in people. This most likely occurs in dogs as well.

While most focus lies on THC and CBD, cannabis contains other medicinal constituents like terpenes and flavanoids. Terpenes are the aromatic oils in the plant. These enhance the medicinal effects of both CBD and THC. Flavenoids are chemical compounds found in plants. These compounds also have medicinal effects such as anti-oxidant, anti-inflammatory, anti-cancer, anti-viral and anti-anxiety. 

 

Conditions Benefited from CBD

The list of conditions that are improved by cannabis grows daily in my practice. Often I recommend cannabis to treat one ailment, only to find it has improved other symptoms. These are the best side effects! These are the conditions I have seen improved with cannabis:

  • Anxiety
  • Arthritis/Pain
  • Aggression
  • Seizures
  • Asthma
  • Allergies
  • Inflammatory Bowel Disease
  • Increased Immune Function
  • Appetite Stimulation

I also use cannabis for patients with cancer. Depending on the type of cancer, CBD may slow the progression and offer the pet an increased sense of well being. Each type of cancer has different properties and behavior and will respond differently to CBD.

Dosing

Good news! Colorado State University is currently conducting clinical trials for the use of CBD in seizures and arthritis. As more research gets funded, we may begin to have a more information for the best dosing regimen. As it stands currently I use a wide dosing range of 0.1-3 mg/kg twice daily. My recommendations depend on the animal and the disease being treated.

Product Selection

As products flood the market, it is important that consumers make an educated purchases for themselves and their pet. My inbox is full of people asking about products they have purchased or considering purchasing. When I vet these products, I am looking for the following criteria.

  1. Farming practices.Has the plant been grown with the use of pesticides?
  2. Extraction method. Watch out for methods that use chemicals as these residues will be present in the final product.
  3. Some products contain too little CBD to be effective.
  4. Guaranteed analysis. Does the company test their product for the constituents beyond THC and CBD? Does it look at the terpenes and flavonoids? Check out the HempRx guaranteed analysis here.
  5. Other ingredients. Make sure you know what other ingredients are present. I prefer HempRx because it only contains hemp. For my very sensitive patients introducing one ingredient at a time is beneficial.
  6. Terpene/Flavanoid. As discussed earlier, CBD and THC are not the only medicinal components of cannabis. I only use products that have the terpene and flavanoid profile analyzed as well.

My absolute favorite product line is HempRx by Rx Vitamins for Pets. This line is specifically made for cats and dogs. It comes in an oil and chewable form. The oil comes in two concentrations so that dosing large dogs can become more affordable. The HempRx Soft Chewz (Cats/Small Dogs & Larger Dogs) are very palatable for picky pets.

For cats I recommend getting the regular strength HempRx and starting with 1-2 drops twice daily. This bottle will last approximately 2-3 months.

For dogs greater than 20 lbs I recommend the HempRx Forte as it will be the most economical.

Sending love to you and your furry friends!

My cat is about two years old and in the past 30 days has started pulling out the hair on it’s tail with his teeth. But he has now started pulling out the hair on other parts of his body. I’ve raised cats all my life and I’ve never seen this. Would CBD oil help out?

Claire Primo, Veterinary Nurse for BHV

Hi Cathy,

Oh no! What does your kitty’s regular veterinarian think is going on?

CBD is great for anxiety, so if it’s anxiety related,it absolutely has the potential to help!

For kitties, we usually recommend the HempRx.

Please keep us posted!

Warmly,
Claire

Our siamese was overgrooming all the fur from his belly, legs & tail. Relief came to him when his dermatologist guessed that it may be due to a food allergy & put him on Royal Canin Rabbit & Pea prescription cat food. Truely a miracle for him!

Claire Primo, Veterinary Nurse for BHV

Hi Kendall,

LOVE this story, so very glad your kitty is finally feeling relief. As a pet parent, there is no better feeling.

Thank you for sharing, it brings a smile to our faces!

Warmly,

My elderly Border Collie has a slipped disc. I have her on Prednisone, tramadol, muscle relaxer, and an other pain med. I have also made a chiropractor appointment for her. Would Cannabis be beneficial to her. I am at a point that I am beginning to wonder about her quality of life.

HI
I have a 20 yr kitty w fairly severe arthritis in her hips. She is a tabby and pretty slight build currently maintaining her weight at about 5 lbs. She is also a thyroid kitty on methmiziole (spelling) I’d like to start her on some CBD oil for some better pain relief but her vet isn’t real enthusiastic. Are there any concerns with her thyroid issues. I’m interested in her quality of life.

Claire Primo, Veterinary Nurse for BHV

Hi Lori,

Thank you for reaching out!

We have seen CBD be massively helpful for arthritic kitties! It’s been amazing, especially since there aren’t a lot of great options for arthritic cats. For kitties, we usually recommend HempRx and our dosing chart is here.

We have not seen any negative interactions when using CBD and thyroid medications together.

I hope this helps!

Warmly,
Claire

Hey there,
Has there been any studies looking into CBD and treating cats with Hyperesthesia yet?
Since anxiety, pain, inflammation and seizures are all linked to Hyperesthesia, I was hoping to find a more holistic helper for my cat.

thanks for your time

Hi Dr Angie,
My kitty has just been diagnosed with small cell lymphoma, he is about 9 years old and is really having a ruff time right now. He was started on prednisone today, he cries for food but doesn’t eat much and does that only after I offer him a zillion choices. I’m thinking about CBD but my vet will not give me any direction, I have read your thoughts and recommendations and I know that you use it on your cancer patients, can you help me? I’d much appreciate and advice and help that you can give me!
Thanks!
Risa

My dog was just diagnosed with osteosarcoma. He’s in the very early stages of it. I asked my vet about cbd oil and she recommended hemprx forte. I just bought it because it looked very promising. Does anyone know how it does with osteosarcoma?

Hi. I have been using the Hemp Rx by Rx Vitamins for a few years for seizures and arthritic pain in my 16 year old cat. It is wonderful! I recently ordered a new bottle and the oil is green where it has always been clear in the past. I am worried there may be something wrong and was wondering if you know if the formulation for this recently changed causing that color change?

Many thanks!
Michelle

Gibbs is our 50 lb. hound mix with anxiety issues when we travel . I purchased the HempRX Soft Chewz from your site.
On our next road trip should I give him 2 chewz per the directions for his weight? Or start off with one and see how he handles them?
When should I give him the Chewz? Right before we leave or 30-60 mins prior to departure?
Thank you!

Hi Dr. Angie; My elderly dog white pitbull has arthritis and some days is hard for her to walk and she started limps on her right front leg. Then she rests and slows down for a couple of days and gets normal again. Also a few years ago she had surgery on both her back legs (TPLO) and she is on Meloxidyl mg/ml, 1.5 mg/ ml, 200 ml. After I have read about the benefits and reviews of the CBD I want to give it a try. But I want to know if I can give the CBD with the… Read more »

My cat is not eating and I head CBD oil may work. He is 5 kg. What is an appropriate dose?

Claire Primo, Veterinary Nurse for BHV

Hi Heather,

I’m so sorry to hear that your kitty isn’t eating well. 🙁 How long as he not been eating well? If he’s been on a few strike, it would also be worth touching base with his veterinarian as there are other ways to help encourage him to eat!

That said, we do see CBD help as an appetite stimulant!

For cats, we recommend HempRx and our dosing chart is here.

Please keep us posted! 🙂

Warmly,
Claire

Hi Doctor
Our Oscar (canine) has just been diagnosed with TCell lymphoma. We are at a loss. Thinking of doing aggressive chemo, is cbd safe to use in conjunction?
He’s only 6 and we can’t accept that we’ll still loose him in 10-12 months even with treatment. Can you kindly advise?

Claire Primo, Veterinary Nurse for BHV

Hi Maura,

I am so, so sorry to hear about Oscar’s diagnosis. How incredibly overwhelming.

Yes, you can absolutely use CBD in conjunction with chemotherapy. That said, it would not be a bad idea to consult with Oscar’s oncologist as well.

For small dogs, we usually recommend HempRx. For medium/large sized dogs, we recommend HempRx Forte. Here is our dosing chart.

Big, giant hugs to you and your sweet boy.

Warmly,
Claire
