Cannabidiol (CBD) has become an increasingly popular supplement for both humans and animals in recent years. CBD is a chemical compound found in the cannabis plant that does not cause psychoactive effects. An emerging body of research has shown CBD offers potential health benefits ranging from pain and inflammation reduction to seizures and anxiety relief.

Many horse owners are now wondering if CBD could also benefit their equine companions. Here we will explore the key considerations around using CBD oil for horses.

Current Research on CBD for Horses

Most existing research on CBD for animals has focused on dogs and cats. However, some recent studies have investigated how CBD affects horses specifically:

  • A 2020 study found CBD reduced symptoms associated with osteoarthritis in horses. The CBD appeared to be most effective for increasing stride length and reducing localized swelling.
  • Another 2020 study concluded that CBD reduced head shaking in horses. Excessive head shaking can be caused by neuropathic pain. The CBD treatment decreased episodes by 30% over the 4 week study.
  • Several studies have shown promise for CBD calming anxious horses. CBD appears to modulate equine anxiety similarly to humans by interacting with the endocannabinoid system.

While current research remains limited, these initial studies suggest potential benefits particularly for inflammation, pain, and anxiety in horses. More large scale clinical trials are still needed to further confirm effectiveness and proper dosing.

Is CBD Oil Safe for Equine Use?

An appealing aspect of CBD is its favorable safety profile, especially compared to many traditional pharmaceuticals. However, adverse effects are still possible and more research is needed to confirm long-term safety for horses specifically.

Most evidence suggests CBD is well-tolerated by horses when used properly. Minor side effects reported include slight sedation and changes in appetite or gastrointestinal function.

One study analyzed potential liver damage from CBD in horses. No negative impacts were found on liver enzymes or function when horses received the CBD orally for 42 days.

It’s important to consult an equine veterinarian before using any new supplement. Your vet can review your horse’s individual health conditions to determine if CBD could be beneficial or interact with any current treatments.

Choosing a High-Quality CBD Supplement

One challenge pet owners face is finding a CBD product made specifically with animal health in mind. The largely unregulated CBD market has led to many low quality or inaccurately labeled products.

When selecting a CBD supplement for your horse, check for a product designed for animal use from a reputable brand. Only choose supplements intended for oral consumption and formulated for equines.

Here are the key signs of a quality CBD oil product:

  • Type of CBD: Opt for broad or full-spectrum CBD over CBD isolates. Broad spectrum CBD contains other beneficial cannabis compounds.
  • Source: CBD from organically grown American hemp is ideal. Ensure the CBD is extracted without any harsh solvents.
  • Lab testing: Third party lab testing confirms the potency and safety. Certificates of Analysis (COAs) should be available.
  • Dosing: Clear serving guidelines tailored to horses should be provided. Start with smaller servings and monitor your horse.

Purchasing through a veterinarian allows them ensure proper usage and vet any adverse effects. Some CBD products may also require a prescription.

Introducing CBD to Your Horse

Once you’ve selected an appropriate CBD supplement, here are some tips for safely integrating it into your horse’s routine:

Check with your vet – Always get veterinary approval before starting CBD, especially if your horse takes any medications or has underlying conditions.

Start low and go slow – Begin with a very low dose, such as the product’s minimum recommended serving. Then gradually increase to the full therapeutic dose if no adverse effects occur after one week.

Find the best administration method – Many equine CBD oils can simply be drizzled over feed or treats. You can also administer directly into the mouth. Find which method your individual horse tolerates best.

Split into multiple daily servings – Dividing CBD into two or three servings spaced throughout the day can improve absorption and effects compared to a single large dose.

Monitor changes – Keep an eye out for improvements related to joint mobility, nerve pain, anxiety, gastrointestinal issues or other symptoms. Track any side effects as well. Report your observations to your veterinarian.

While controlled studies on CBD for horses remain limited, anecdotal evidence from horse owners continues growing. If current trends around CBD in human health translate to horses, we can likely expect expanded cannabinoid research and treatment options for equines in the coming years.

What Conditions Could CBD Help With in Horses?

While research is still in early stages, current evidence and pet owner testimonials suggest CBD oil may help horses suffering from certain conditions.

CBD interacts with the endocannabinoid system (ECS), a network of receptors found in mammals, birds, reptiles and other creatures including horses. The ECS regulates various physiological processes related to pain, stress, appetite, mood and more.

By modulating this system, CBD offers therapeutic potential for several common health issues faced by modern domestic horses. Here are some of the main conditions CBD could potentially assist with:

Arthritis & Joint Pain Relief

Advanced age, athletic training and injury can lead to degenerative joint diseases like arthritis and bursitis in equines. These painful inflammatory conditions frequently occur in leg joints and the back. CBD and other cannabis compounds have shown anti-inflammatory properties in humans.

Early research suggests CBD can reduce local swelling and ease associated pain/stiffness from arthritis in horses as well. The relaxing effects of CBD may also prove useful in soothing muscle tension or soreness from athletic exertion.

Anxiety & Stress Reduction


Many horses suffer from anxious temperaments or situational stressors like trailering, veterinary visits or separation from herd mates. This can be dangerous if anxiety leads to panicked flight responses. CBD has reliably reduced anxiety symptoms in both human and animal studies through its effects on serotonin receptors.

While more equine-specific research is still needed, CBD oil shows promise for mitigating anxiety and stressed behaviors if administered properly. It may be particularly helpful in high-stress situations like competitions or vet examinations.

Neuropathic Pain & Head Shaking Relief

Trigeminal-mediated headshaking syndrome causes horses to compulsively shake their heads. This appears associated with neuropathic facial pain, similar to trigeminal neuralgia in humans.

Initial research found horses receiving CBD treatment shook their heads 30% less frequently. The CBD oil also led to higher blood levels of pain-relieving anandamide. This suggests CBD can alleviate nerve-related face pain to reduce associated head shaking in horses.

Supporting Gastrointestinal Health

Stomach ulcers and dysbiosis, an imbalance of gut microflora, frequently impact performance horses. These common gastrointestinal issues can cause diarrhea, discomfort, poor coat quality and abdominal pain leading to decreased appetite.

Through anti-inflammatory effects and modulating intestinal mobility/secretion, some evidence indicates CBD may support horses experiencing inflammatory bowel diseases, digestion difficulties or poor gut health. More research is still needed regarding optimal CBD dosing and delivery for equine GI issues.

Stimulating Appetite

Lack of appetite and subsequent weight loss is a common struggle for equine seniors and those with chronic health conditions. The ECS helps control feed intake and digestions processes. Human research has shown CBD can act as a mild hunger stimulant and improve food enjoyment.

While concrete evidence is still minimal, some horse owners have reported improved appetite and weight gain in skinny or finicky elderly horses after integrating CBD into their diet. However, research is still needed on this potential application.

If your horse struggles with any of these issues, consult your veterinarian about whether a CBD supplement could provide additional comfort or support. Most evidence for CBD in horses is preliminary but initial results are promising.

Choosing the Best CBD Administration Method

If you and your veterinarian decide to try CBD oil with your horse, the next consideration is choosing the best administration method. There are pros and cons associated with different ways to give your horse its CBD servings. Key factors to consider are safety, accuracy, convenience and your horse’s tolerance.

Here is an overview of the most common CBD oil delivery methods to help determine the optimal approach:

Mixing into Feed

  • How it works – CBD dosing pipettes or oral syringes allow you to measure then mix oil directly into your horse’s normal feed.
  • Benefits – Mixing into grain or hay-based meals is the most convenient method. It also avoids need to put anything into your horse’s mouth they might resist.
  • Potential issues – Accuracy depends on properly mixing oil throughout the feed. Picky eaters may avoid CBD-laced food or need baiting with other treats first.

Infused Equine Treats/Supplements

  • How it works – Companies produce CBD-infused cookies, pellets, powders and grain mixes formulated specifically for horses to simplify dosing.
  • Benefits – Infused treats provide measured CBD doses in palatable formats. Combining with vitamins/supplements can also boost wellness.
  • Potential issues – Quality and accuracy varies greatly between products. Horses may reject flavors or textures. Treat-based options can also get expensive.

Direct Oral Administration

  • How it works – Using oral syringes without needles, you can squirt CBD oil directly into your horse’s mouth.
  • Benefits – Direct oral CBD administration allows for precise dosing and fast absorption into the bloodstream. This method gives you the most control.
  • Potential issues – Introducing anything unfamiliar into a horse’s mouth can provoke resistance. Getting them to comply takes patience and positive reinforcement.

Adding to Feed Bucket Barrier Oil

  • How it works – Stir measured doses of CBD oil into flavored masking products designed to coat the feed bucket barrier film.
  • Benefits – Flavored barrier oil masks CBD flavor while ensuring full dose is licked up with all feed remnants
  • Potential issues – Achieving homogenous mixing can be messy and time consuming. Cost of purchase barrier product must also be factored in.

Take some time to consider your horse’s personality, existing diet and responsiveness to new supplements. Testing different CBD oil administration techniques can help determine which method works best for you and your equine companion. Consistency is key so once an effective delivery method is established stick with it long-term. Monitor for improvements as well as any dislike of flavor or texture changes. Adjust the approach if necessary to keep your horse compliant with CBD treatment.

Frequently Asked Questions About Using CBD for Horses

Many horse owners have questions about using cannabidiol (CBD) with their equine partners as this supplement grows in recognition. Here we answer some of the most common frequently asked questions about integrating CBD oil into your horse’s routine:

What dose of CBD should I give my horse?

There are no official serving guidelines for horses yet so optimal dosing varies. Many experts recommend starting with 0.5mg – 1mg of CBD per kg of bodyweight twice daily. Then gradually increase every 5-7 days by 0.5mg/kg until desired effects are seen. Divide the target total daily dose into 2-3 servings.

What’s the difference between cannabis, hemp, marijuana and CBD?

  • Cannabis refers to plants from the Cannabaceae family. Marijuana is a variety containing high levels of psychoactive THC. Hemp strains feature low THC levels under 0.3% and higher CBD levels. CBD is one of over 100 active compounds called cannabinoids found in these plants.

Is CBD detected on equine drug tests?

Most equestrian regulatory bodies have banned CBD due to the difficulty distinguishing hemp-derived CBD versus marijuana. However, new testing methods now allow detection of CBD separate from THC. Check your association’s latest guidelines to see their current stance. Many expect more nuanced policies allowing CBD for horses in the future.

Can you give CBD oil to horses daily?

Yes, daily use helps maintain consistent levels of CBD in the body for ongoing therapeutic effects. Long term CBD administration appears safe based on available toxicity reports and studies. Many owners dose their horse with CBD oil every 12 hours or split one daily target amount into 3 portions evenly spaced over 24 hours.

How long does equine CBD oil take to start working?

Horses can experience CBD benefits from the first dose, but maximum results take consistent use over 2-6 weeks allowing compound build-up in the body. Document effects over a 6 week trial period when starting CBD. Track positive impacts as well as any side effects. Stay in touch with your vet throughout.
