CBD Oil for Dogs with Seizures: Considerations & Cautions
As pet owners, we naturally want to do everything in our power to help our dogs lead healthy, happy lives. For those with dogs suffering from epilepsy or frequent seizures, the journey can be particularly challenging. Traditional seizure medications don’t always work for every dog, and in some cases, the side effects can be significant. This has led many to explore alternative options, including CBD oil. But while CBD oil holds promise, it’s crucial to approach it with a full understanding of the considerations and cautions involved.
Understanding the Potential Benefits and Risks of CBD Oil
Cannabidiol (CBD) has gained considerable attention for its potential to reduce seizures, particularly in dogs that don’t respond well to traditional medications. Research, such as the study by McGrath et al. (2019), has shown that CBD can reduce seizure frequency by as much as 50% in some dogs. However, it’s important to note that this benefit is not universal; the response to CBD varies from dog to dog, and large scale seizure reduction was the same between placebo groups (those not taking CBD) and those taking CBD. Some dogs experience significant improvement, while others see little to no change. This variability highlights the need for careful consideration before adding CBD to your dog’s treatment plan.
CBD and Liver Health: A Critical Consideration
One of the key concerns with CBD oil is its effect on the liver. Research indicates that CBD can lead to elevated liver enzymes in some dogs, which is a potential sign of liver stress. While elevated enzymes themselves do not necessarily indicate liver damage, they do suggest that the liver is working harder than normal to process substances, in this case, CBD.
Why Liver Health Matters
The liver plays a crucial role in metabolising and detoxifying substances that enter the body, including medications. When CBD is administered, it is processed by the liver before entering the bloodstream. This process can place additional strain on the liver, particularly if the dog is already taking other medications that the liver must metabolise, such as traditional seizure medications like phenobarbital.
Phenobarbital, commonly used in treating epilepsy in dogs, is known for its hepatotoxic effects, meaning it can cause liver damage over time. When CBD is added to the treatment regimen, the liver's workload increases, potentially amplifying the risk of liver damage. This is especially concerning in dogs that have existing liver conditions or those that are on multiple medications.
Monitoring and Managing Liver Health
Given the potential for CBD to affect liver enzymes, regular monitoring of liver function is essential if you’re considering CBD for your dog. This involves routine blood tests to check liver enzyme levels, which can help your veterinarian detect early signs of liver stress or damage.
The Importance of Considering Drug Interactions
Another critical aspect to consider is CBD’s potential to interact with other medications. CBD can affect how drugs are metabolised by inhibiting certain enzymes in the liver responsible for drug breakdown. This interaction can lead to higher levels of the drugs in the bloodstream, which can increase the risk of side effects or toxicity.
For dogs on seizure medications, the interaction between CBD and drugs like phenobarbital or potassium bromide needs careful consideration. CBD’s influence on liver enzymes can alter the levels of these medications in the blood, potentially making them less effective or increasing their toxicity.
Collaboration with Your Veterinarian
It's crucial to work closely with your veterinarian when adding CBD to your dog’s treatment plan. Your vet can help adjust dosages, schedule regular liver function tests, and assess whether CBD is a safe option for your dog. This collaborative approach ensures that any potential risks are managed effectively, and your dog’s health is closely monitored.

Additional Risks and Side Effects of CBD
While CBD is generally well-tolerated, it’s important to be aware of other potential side effects and risks that have been reported in studies. Understanding these can help pet owners manage expectations and respond appropriately should they arise.
1. Gastrointestinal Issues
Why They Occur: CBD can affect the gastrointestinal tract in several ways. Primarily, CBD influences the endocannabinoid system, which plays a significant role in regulating gut function and inflammation. While it can help modulate these functions, in some dogs, it may disrupt normal gastrointestinal activity leading to symptoms like diarrhoea, vomiting, and changes in appetite.
Precautions: If these symptoms occur, it's essential to evaluate the dosage of CBD, as these effects may be dose-dependent. Providing CBD with food can sometimes mitigate upset stomach symptoms. However, persistent gastrointestinal issues should be addressed with your veterinarian to adjust the CBD dosage or explore other treatment options. Continuous symptoms could indicate a more serious underlying issue that might require discontinuation of CBD.
2. Changes in Mobility and Coordination
Why They Occur: CBD’s effect on the central nervous system, which can be beneficial for reducing seizures, may also impact nerve function and muscle coordination temporarily. Ataxia (a degenerative disease of the nervous system) or increased lethargy are potential side effects, possibly due to CBD’s sedative properties at higher doses or its modulation of neurotransmitters involved in movement.
Precautions: Monitoring the dose of CBD is crucial, and observing your dog's reaction when starting or changing dosages is essential. If your dog shows signs of impaired movement or seems unusually lethargic, consult your vet. Adjusting the CBD dose or the timing of administration might be necessary. Ensuring a safe environment where the dog can move without the risk of injury is also important if motor coordination is affected.
3. Anxiety and Behavioural Changes
Why They Occur: While CBD is known for its calming effects, paradoxical reactions such as increased anxiety or unusual behavioural changes can occur. These reactions might be due to CBD’s complex effects on the brain’s serotonin receptors, which are crucial for mood regulation. In some cases, the anxiety might not stem directly from CBD itself but from other ingredients in the product or from the dog's individual sensitivity to cannabinoids.
Precautions: Close observation of your dog's behaviour after administering CBD is vital. If signs of increased anxiety or behavioural changes are noted, it’s important to evaluate the type of CBD product used, the dosage, and the frequency of administration. Discussing these changes with your veterinarian can help determine if CBD is suitable for your dog or if adjustments are needed. Sometimes, a gradual introduction to CBD or switching to a different CBD formulation can help alleviate these side effects.
The Importance of Quality: Not All CBD Oils Are Created Equal
One of the biggest challenges in using CBD oil for dogs is the lack of regulation in the market. Unlike pharmaceuticals, CBD products are not regulated by the Food and Drug Administration (FDA), which means that the quality, concentration, and even the contents of these products can vary widely. This lack of regulation can lead to significant risks, particularly if you inadvertently purchase a low-quality or contaminated product.
1. Synthetic CBD and Low-Quality Products
One of the major dangers in the unregulated CBD market is the prevalence of synthetic CBD. Unlike natural CBD, which is derived from the cannabis plant, synthetic CBD is created in a lab and can have unpredictable effects. These synthetic products are often cheaper but can be far more dangerous. There have been reports of serious adverse effects from synthetic cannabinoids, including severe gastrointestinal issues, neurological problems, and in extreme cases, death.
Low-quality CBD products may also contain harmful contaminants, such as heavy metals, pesticides, or residual solvents used during the extraction process. Additionally, some products may contain higher levels of THC than advertised, which could be harmful to your dog.
2. What to Look for in a Quality CBD Oil
Given the risks associated with low-quality and synthetic CBD, it’s crucial to be diligent when selecting a CBD oil for your dog. Here are some key factors to consider:
Third-Party Testing: Always choose a product that has been tested by an independent third-party lab. This testing should confirm the concentration of CBD, ensure the absence of THC, and check for contaminants like heavy metals, pesticides, and solvents.
Organic Certification: Opt for CBD oil that is sourced from organically grown hemp. Organic farming practices reduce the risk of pesticide contamination and ensure a cleaner product.
Transparency: Reputable companies should be transparent about their sourcing, extraction methods, and testing results. Avoid companies that are vague about where their hemp comes from or how their products are made.
Customer Reviews and Reputation: Look for products from well-established companies with positive reviews from other pet owners. Word of mouth and customer experiences can provide valuable insight into a product’s effectiveness and safety.
