Watching your dog have a seizure is terrifying. One minute they're fine, the next they're convulsing on the floor and you feel completely helpless. If your dog has epilepsy, you've probably been down the road of trying different medications, dealing with side effects, and still seeing breakthrough seizures.

More dog owners and veterinarians are exploring CBD as an additional tool for managing canine epilepsy. While it's not a cure and shouldn't replace proper veterinary care, research suggests CBD might help reduce seizure frequency in some dogs, often with fewer side effects than traditional medications.

This is serious medical territory that requires close veterinary supervision. If you're already familiar with  CBD dosing basics or senior dog health issues, seizure management requires a different approach entirely.

Understanding Canine Epilepsy and Seizures

Understanding Canine Epilepsy and Seizures

Dog seizures aren't all the same, and understanding what you're dealing with helps determine if CBD might be helpful as part of your dog's treatment plan.

Types of Seizures in Dogs:

Generalized Seizures (Grand Mal): These are the scary ones most people think of - your dog loses consciousness, falls over, and has convulsions with paddling motions. They might drool, lose bladder control, or make noise.


Focal Seizures: These affect just part of the brain and might look like strange behaviors - repetitive movements, staring, or unusual responses to things around them. Your dog stays conscious but acts weird.


Cluster Seizures: Multiple seizures happening close together, which is an emergency situation requiring immediate veterinary care.


Status Epilepticus: A seizure lasting more than 5 minutes or continuous seizures without recovery time. This is life-threatening and needs emergency treatment.

What Causes Seizures in Dogs:

Idiopathic Epilepsy: This means "we don't know what causes it" and accounts for most epilepsy in dogs. It usually shows up between 1-5 years of age and seems to have a genetic component.


Structural Epilepsy: Caused by brain tumors, head trauma, infections, or other physical problems in the brain.


Reactive Seizures: Triggered by things like low blood sugar, liver disease, kidney problems, or toxin exposure.


Breed Predispositions: Some breeds are more prone to epilepsy, including German Shepherds, Labrador Retrievers, Golden Retrievers, Beagles, and several terrier breeds. If you have one of these breeds, you might be more likely to deal with seizures.

The Reality of Living with Epileptic Dogs:

Most dogs with well-controlled epilepsy live normal, happy lives. The goal isn't necessarily to eliminate all seizures (though that would be great) but to reduce their frequency and severity while maintaining good quality of life.

How CBD May Help Control Seizures

The research on CBD for dog seizures is still developing, but early studies and real-world experience are encouraging.

What the Research Shows:

A 2019 study at Colorado State University found that dogs receiving CBD along with their regular seizure medications had significantly reduced seizure frequency compared to dogs getting placebo. The dogs getting CBD had a median reduction of 33% in seizure frequency.


Human epilepsy research is further along, and CBD has been approved by the FDA for certain types of human epilepsy. While dogs aren't humans, this research provides insight into how CBD might work for seizures.

How CBD Might Work in the Brain:

CBD appears to interact with several brain systems involved in seizure activity. It may help stabilize electrical activity in the brain and reduce the likelihood of abnormal electrical storms that cause seizures.


CBD also has anti-inflammatory properties, and brain inflammation can contribute to seizure activity in some cases.

What Dog Owners Report:

Many owners using CBD for their epileptic dogs report:

  • Reduced seizure frequency

  • Less severe seizures when they do occur

  • Faster recovery after seizures

  • Better quality of life between seizures

  • Fewer side effects compared to increasing traditional medications

Important Limitations:

CBD doesn't work for every dog with seizures. Some dogs see dramatic improvement, others see modest reduction in seizure frequency, and some don't respond at all.


CBD works best as an add-on treatment rather than a replacement for proven seizure medications. Most success stories involve CBD used alongside traditional treatments.

Realistic Expectations:

If your dog currently has 8 seizures per month, CBD might help reduce that to 4-5 seizures per month. For many families, even that reduction makes a huge difference in quality of life.

CBD Dosage for Seizure Management

Seizure control typically requires higher CBD doses than anxiety or general wellness, and dosing must be extremely consistent.

Starting Doses for Seizure Control:

Seizure management usually requires doses at the higher end of safe ranges, but you still need to start conservatively and work up.


Small Dogs (10-25 lbs):

  • Start with: 5-8mg daily

  • Often need: 10-15mg daily

  • Some require: Up to 20mg daily

Medium Dogs (26-60 lbs):

  • Start with: 10-15mg daily

  • Often need: 20-30mg daily

  • Some require: Up to 40mg daily

Large Dogs (61-100 lbs):

  • Start with: 15-25mg daily

  • Often need: 30-50mg daily

  • Some require: Up to 60mg daily

Extra Large Dogs (100+ lbs):

  • Start with: 25-35mg daily

  • Often need: 40-70mg daily

  • Some require: Up to 80mg daily

Critical Dosing Rules for Seizures:

Consistency is Everything: Seizure control requires giving CBD at exactly the same times every day. Missing doses or irregular timing can trigger breakthrough seizures.


Twice Daily Dosing: Most dogs with seizures do better with CBD given every 12 hours rather than once daily. This maintains more stable blood levels.


Slow Increases: Increase doses gradually over weeks, not days. Sudden changes in CBD levels might actually trigger seizures in sensitive dogs.


Never Stop Suddenly: If you need to stop CBD for any reason, taper down slowly over several days to avoid rebound seizures.

Adjustment Timeline:

Week 1-2: Start with conservative dose, maintain seizure log Week 3-4: Increase if needed, continue monitoring Week 5-8: Continue gradual increases until seizure frequency improves Maintenance: Once effective, maintain exact dosing schedule.

Working with Blood Levels:

Some veterinary neurologists can measure CBD blood levels to help optimize dosing, similar to how they monitor traditional seizure medication levels.

Working with Your Veterinarian

Working with Your Veterinarian

This cannot be stressed enough: seizure management requires professional veterinary oversight. CBD should never be used as a DIY seizure treatment.

Before Starting CBD:

Your vet needs to know about any plans to add CBD to your dog's seizure management plan. They can help determine if it's appropriate and safe with your dog's current medications.


Some seizure medications can interact with CBD, requiring dose adjustments of either the CBD or the traditional medications.

Medication Interactions to Consider:

Phenobarbital: CBD might increase phenobarbital levels in the blood, potentially requiring phenobarbital dose reductions.


Potassium Bromide: Generally considered safe to combine with CBD, but monitoring is still important.


Levetiracetam (Keppra): Usually safe with CBD, but individual responses can vary.


Zonisamide: Limited interaction data, but close monitoring is recommended.

What Your Vet Needs to Know:

  • Exact CBD product and concentration you plan to use

  • Proposed dosing schedule

  • Your dog's current seizure frequency and severity

  • All current medications and supplements

  • Your dog's seizure history and response to previous treatments

Monitoring Requirements:

Dogs on CBD for seizures often need more frequent blood work to monitor liver function and check levels of other seizure medications.


Your vet might want to see your dog every 3-4 months initially, then every 6 months once things are stable.

Emergency Planning:

Make sure your vet knows your dog is on CBD if you need emergency seizure treatment. Some emergency medications might interact with CBD.

Monitoring Seizure Frequency on CBD

Tracking seizures becomes even more important when adding CBD to your dog's treatment plan.

Monitoring Seizure Frequency on CBD

What to Track:

Seizure Frequency: How many seizures per week or month. This is the most important number for determining if CBD is helping.


Seizure Duration: How long each seizure lasts. Shorter seizures are better than longer ones.


Seizure Severity: Rate seizures on a scale of 1-5 based on intensity and your dog's recovery time.


Recovery Time: How long it takes your dog to act normal after a seizure.


Seizure Timing: Note if seizures happen at particular times of day or in relation to stress, weather changes, or other triggers.


CBD Timing: Record exactly when you give CBD to help identify patterns.

Creating a Seizure Log:

Date and time of seizure Duration (use a timer if possible) Severity rating Any potential triggers you noticed Recovery time CBD dose and timing for that day.

Using Technology:

Several smartphone apps are designed for tracking seizures. Some popular ones include SeizureTracker, EpiDiary, and Seizure Log.

What Improvement Looks Like:

Frequency Reduction: Going from 6 seizures per month to 3-4 seizures per month represents meaningful improvement.


Severity Reduction: Seizures that are shorter or less intense, even if frequency doesn't change dramatically.


Faster Recovery: Your dog bouncing back more quickly after seizures.


Better Quality of Life: More normal behavior between seizures, less post-seizure confusion or anxiety.

Timeline for Seeing Results:

Unlike anxiety or pain management, seizure control often takes 2-3 months to evaluate properly. You need enough time to see if seizure patterns are actually changing.


Don't expect immediate results. Seizure control is a long-term management strategy, not a quick fix.

Success Stories: Seizure Reduction

While we don't have specific customer testimonials for seizure management from the provided reviews, veterinary case studies and published research provide insight into CBD's potential for seizure control.

Research-Based Success Stories:

The Colorado State University study that followed 26 dogs with epilepsy found that 89% of dogs receiving CBD had reduced seizure frequency. The average reduction was 33%, with some dogs experiencing even greater improvement.

Veterinary Case Reports:

Veterinary neurologists report cases where dogs who weren't well-controlled on traditional medications alone achieved better seizure control when CBD was added to their treatment plan.


Some dogs have been able to reduce doses of traditional seizure medications when CBD is added, reducing side effects while maintaining seizure control.

Common Patterns in Success Stories:

  • Most improvement happens gradually over 2-3 months.

  • Dogs often have fewer severe seizures even if total frequency doesn't change dramatically.

  • Many dogs seem more alert and engaged between seizures.

  • Families report less anxiety about their dog's condition when seizures are better controlled.

Realistic Outcomes:

Success with CBD for seizures usually means "better management" rather than "seizure-free." While some dogs do become seizure-free with CBD, most families consider treatment successful if seizure frequency decreases significantly and quality of life improves.

When CBD Doesn't Help:

It's important to acknowledge that CBD doesn't work for every dog with seizures. Some dogs show no improvement, and occasionally dogs might even have increased seizure activity when starting CBD (which is why veterinary supervision is crucial).


If CBD doesn't help after 3-4 months of consistent use at appropriate doses, it might not be the right tool for your dog's seizure management.

Important Reminders:

Never stop traditional seizure medications to try CBD alone. CBD works best as an addition to proven treatments, not a replacement.


Always work with a veterinarian experienced in seizure management. While your regular vet might be comfortable with CBD for other conditions, seizure control often benefits from specialist input.


Seizure management is a marathon, not a sprint. Focus on long-term patterns rather than individual seizures when evaluating if treatment changes are helping.

Is CBD Happy-Furever™ safe for dogs?

As the stigma surrounding hemp-derived CBD continues to lessen, there’s no reason not to try CBD for your dog. However, we understand why some are still skeptical because in many ways CBD sounds too good to be true. So, we'll put your mind at ease, here’s why you’d be making the right choice:


Reputable health organizations all over the world including the  World Health Organization (WHO) have deemed CBD a ‘safe & effective’ health alternative for both humans and animals. It's well-tolerated even in high doses, and it has very mild side effects.


Both Hemp and Marijuana are species of cannabis plants, and while they have the same cannabinoids and terpenes, the percentages and ratios differ immensely.


In particular, Hemp contains very low amounts of tetrahydrocannabinol (THC), where Marijuana contains higher percentages. High levels of THC results in the euphoria associated with marijuana.


Marijuana has approximately 20-30 % THC vs. industrial hemp 0.01-0.3% THC indicating marijuana has one hundred to a thousand times more tetrahydrocannabinol than hemp, a significant difference.


Happy-Furever only uses the highest quality CBD extracted using an industry-leading CO2 Extraction Process, making sure that the raw crops are not overheated or overprocessed, keeping the plant's diverse array of cannabinoids available. Watch as your dogs experience the positive benefits within days.

Which order option is right for me?

Many of our customers that have experienced the biggest, fastest results go with the 6-bottle option, as it comes with the free gifts and it also allows them to use the oil on their dogs for a long time. The key here is you want your dogs exposed to the benefits of CBD Happy-Furever for a prolonged period of time.


While we believe you can still experience positive results with 1-3 bottle options, we know dog parents who are determined to make a change in their dog's lives and reclaim their dog's health and energy always go with the 3 or 6 bottle option because it saves them the most money, and it ensures they never miss a single day of Happy-Furever's powerful support.


Imagine for less than a cup of coffee per day, you get to unwind the clock and let your dogs experience the kind of energy, vitality, and happiness they used to back when they were puppies.


So go ahead and order your supplies, and once again - your order is covered by our 180-day moneyback guarantee.
