Seizures in dogs can be alarming, leaving pet parents desperate for safe, effective treatments. With interest growing in natural remedies, many are asking: does CBD help dogs with seizures? Early research and owner experiences suggest CBD may reduce seizure frequency, especially when used alongside traditional anti-seizure medications.

In this guide, we’ll cover what causes seizures in dogs, the signs to watch for, how CBD works in the body, current research findings, safety considerations, and practical advice for dog owners exploring this option.

Key Takeaways

  • CBD may reduce seizure frequency in dogs by calming overactive neurons through the endocannabinoid system. Some studies show up to 33% fewer seizures when CBD is added to standard treatments.

  • Full-spectrum CBD products are generally well tolerated with fewer side effects than many seizure drugs, but correct dosing (2–5 mg/kg) and veterinary supervision are essential.

  • Quality matters: Choose pet-specific CBD oils with third-party testing, clear ingredient lists, and verified cannabinoid content—such as PawOrigins® Happy-Furever™ Full-Spectrum CBD Oil.

CBD works best as part of a comprehensive treatment plan, not as a replacement for prescription medications. Ongoing vet guidance ensures safe and effective results.


Understanding Seizures in Dogs

Dogs ear infection

Seizures are one of the most common neurological issues in dogs. They happen when abnormal electrical activity in the brain causes involuntary movements or loss of awareness.

Types and Causes

  • Idiopathic epilepsy: The most common type, often inherited, with no identifiable cause.

  • Structural epilepsy: Linked to brain abnormalities such as tumors, injury, or inflammation.

  • Reactive seizures: Caused by external factors like toxins, low blood sugar, or metabolic issues.

Risk factors include genetics, head trauma, organ disease, or poisoning. Some breeds—like Border Collies, Labrador Retrievers, and Australian Shepherds—are more prone to epilepsy.

Common Symptoms

Dogs may show warning signs before a seizure (aura, pre-ictal phase), such as restlessness or confusion. The seizure itself (ictal phase) can involve:

  • Sudden collapse and muscle spasms

  • Twitching or paddling legs

  • Excessive drooling or foaming saliva

  • Temporary unconsciousness

  • Loss of bladder or bowel control

Afterward (post-ictal phase), dogs may appear disoriented, unsteady, or temporarily blind. Recognizing these patterns is vital for getting timely veterinary care. Watch how these stages actually look like in real dogs:

What Is CBD and How Does It Work in Dogs?

CBD, or cannabidiol, is a non-psychoactive compound found in hemp. Unlike THC, it does not produce a “high.” Instead, CBD interacts with the  endocannabinoid system (ECS) —a network of receptors in the brain, nerves, and immune system that helps regulate balance (homeostasis).

CBD’s Neurological Impact

  • CB1 and CB2 receptors in the ECS help control neuron firing, mood, and inflammation. CBD interacts with these receptors, potentially calming overactive brain activity.

  • CBD may increase natural endocannabinoids like anandamide, which further stabilizes nerve signals.

  • Early studies suggest CBD supports neuroprotection, helping reduce seizure severity and frequency.

Unlike many seizure drugs, which can cause liver strain or heavy sedation, CBD is generally gentler when used correctly.

Current Research on CBD for Dog Seizures

Scientific interest in CBD has expanded rapidly, especially for treatment-resistant epilepsy in dogs.

Clinical Trials and Findings

  •  Colorado State University (CSU) Study: Dogs given hemp-derived CBD oil alongside seizure medications had an average 33% reduction in seizures compared to placebo. Side effects were mild, such as digestive upset or temporary liver enzyme changes.

  • Other Veterinary Studies: Similar results suggest CBD can be a useful adjunct therapy, especially for dogs unresponsive to standard drugs. However, not all dogs respond the same way, and more large-scale research is needed.

Key Takeaways from Research

  • CBD is not a cure, but it may reduce seizure frequency in certain cases.

  • Effectiveness varies—some dogs show dramatic improvements, while others show little change.

  • Consistent dosing and veterinary oversight improve outcomes.

Safety and Side Effects of CBD in Dogs

CBD’s safety profile is generally favorable, but side effects can occur, especially with high doses or poor-quality products.

Possible Side Effect

  • Mild drowsiness or lethargy

  • Diarrhea or appetite changes

  • Temporary spikes in liver enzymes

.

Drug Interactions

CBD is metabolized by the liver and may affect how other medications—particularly phenobarbital or potassium bromide—are processed. Your vet may need to adjust dosages and run bloodwork to ensure safety.

Dosage Guidance

Research suggests 2–5 mg per kg of body weight, twice daily, but exact needs vary. Always:

  • Start low and increase gradually

  • Use pet-specific CBD products with verified potency and no THC

  • Work closely with your veterinarian

CBD vs. Traditional Seizure Medications

Traditional drugs like phenobarbital, potassium bromide, and levetiracetam remain the first-line treatment for canine seizures. They are effective but can cause side effects like sedation, thirst, or liver toxicity.CBD offers a natural, gentler option that may help when standard drugs don’t fully control seizures. It works best as a supplementary treatment, not a replacement. Many vets recommend combining CBD with prescription drugs to maximize seizure control while minimizing side effects.

Practical Considerations for Pet Parents

When considering CBD for dog seizures, keep these points in mind:

Conclusion: Is CBD Helpful for Dogs with Seizures?

So, does CBD help dogs with seizures? Current research suggests CBD can reduce seizure frequency in some dogs—particularly those with epilepsy not well controlled by traditional drugs. While it’s not a standalone cure, CBD is a promising adjunct therapy when used under veterinary guidance.


For best results, pair CBD with prescription treatments, use high-quality pet-specific products, and maintain ongoing communication with your veterinarian. With the right approach, CBD can play a valuable role in improving seizure control and quality of life for many dogs.

How soon can I expect results?

The response time to CBD Happy-Furever™ can indeed differ from one dog to another, as it is a natural supplement that dogs may need time to adapt to. Many dog parents have observed noticeable positive changes in their pets' behavior and well-being within just a few days of starting the supplement. Common early signs of the supplement taking effect include better sleep, a calmer demeanor, and an increased appetite—all indicators of a content and healthy dog.


As the weeks go by, further enhancements in your dog's health may become evident. You may notice a shinier coat, a reduction in bodily pains, and an increase in energy, evident from bursts of playful excitement like the "zoomies" during fetch.


It's crucial to acknowledge that, like humans, some dogs may require a longer period to fully benefit from natural supplements like CBD oil. Patience is key, and during this time, it's also important to continue reinforcing good behavior.


When CBD helps to bring your dog to a more tranquil state, it's an opportune moment to introduce new habits and work on phasing out any undesirable behaviors. Remember, while CBD can support your dog's well-being, it is not a substitute for consistent training and conditioning.


Keep an eye out for signs of improvement; sometimes, they may not be immediately obvious. Documenting your dog's journey with videos and photos can help you recognize progress that you might otherwise overlook.


Furthermore, improvements might be taking place internally, such as enhanced immune function or reduced inflammation, which aren't always visible. The absence of health issues can often be a silent testament to the efficacy of the supplement, reflecting your dog's overall health and vitality. So, while some benefits of CBD are seen, others are felt—a healthy dog is a happy dog, inside and out.

Will these products make my pet 'high'?

Absolutely not! It's not possible for dogs to get 'high' off our CBD as they contain less than 0.3% THC, which won't cause any intoxicating effects. However, your pup might seem a lot more relaxed, and might be sleeping more - which is a healthy sign! Keep in mind that young puppies and senior dogs should be sleeping for up to 18-20 hours of their day, while adult dogs sleep approximately 16 hours.


The lack of quality sleep can affect their health and anxiety in many ways.


CBD can make older pooches act ‘puppy-like’ and nervous young pups feel calm. The ingredients that makeup hemp contribute to a balanced mood, resulting in a sense of relaxation for your pet.
