Phenobarbital is one of the most common prescribed medications for dog seizures. What if I told you there is a natural alternative, CBD. Hello, everyone! This week I want to talk to you about CBD oil for dogs. Specifically, I would like to address how CBD oil could significantly help your dog wit

Dog Seizures: CBD vs. Phenobarbital

When it comes to controlling seizures in animals, there are many different options for pet parents to consider. One of the most commonly prescribed antiepileptic drugs used by veterinarians today is Phenobarbital.

Despite its widespread use, the side effects of phenobarbital are potentially devastating for pets. While it is relatively effective at keeping seizures at bay, PB is known to dramatically affect our pet’s quality of life by simultaneously putting significant strain on their liver.

As an alternative, CBD from a full spectrum hemp extract has powerful anti-epileptic properties. Research shows it is an effective way to control seizures in dogs while avoiding the numerous negative side effects associated with pharmaceutical drugs like Phenobarbital.

What is Phenobarbital for Dogs?

Phenobarbital is part of the family of drugs called barbiturates, and can be found under various brand names such as Lumina, Solfoton and Tendral.

It was first synthesized for human use waaaaay back in 1911.

It is one of the oldest synthetic drugs still in wide use today. Initially, it was formulated as a hypnotic and sedative, but in February 1912, a young clinical assistant discovered it’s antiepileptic properties and the rest is history…

Since then, it has been widely used for humans and pets alike as an anti-epileptic, but not without its own set of side effects and risks.

How is it administered?

In most cases, phenobarbital for dogs is administered orally, once or twice a day. It comes in both tablet and liquid form, as well as intravenously at veterinary offices.

Various dosages are given based on a dog’s weight and the severity of seizures, among other factors, as sensitivity to this drug ranges quite a bit.

How does it work?

Phenobarbital works by suppressing electrical impulses within your pet’s brain and depressing the central nervous system. Think of it like turning down the volume on your car radio. Less energy through the system means less peaks on the high end.

‘Barbiturates’ like PB are metabolized primarily by the liver and secreted by the kidneys making them potentially problematic when combined with other drugs.

According to Dr. Zac Philossoph, phenobarbital takes a couple of weeks to reach stable blood concentration levels and may not be effective immediately. Consistency is especially important with this drug, as missed doses can result in a recurrence of seizures.

Depending on the case, there are varying degrees of effectiveness with this drug. It does not necessarily stop seizures altogether, in fact, Dr. Carla Johnson reports that in most cases it only reduces seizures frequency by 50%.

Seizures and Epilepsy

Seizures are caused by an excess of electrical energy in your dog or cat’s brain. CBD Dog Health’s chief veterinary officer, Dr. Zac Philossoph uses the analogy of seizures as a ‘brain sneeze’. That sounds cute, but seizures can be very scary.

When neurons begin misfiring and overactivating, it can cause all the hallmarks of a seizure.

  • Spasmodic jerks throughout the body
  • Loss of motor function
  • Loss of consciousness

Dog seizures happen for a range of reasons. Some occur because of structural damage to the brain, some because of interactions with elements in our dogs’ environment. In addition, some breeds are just more prone to seizures than others.

Classification of seizures is done a couple of ways. First, seizures are classified with regard to the underlying cause of the seizure.

What Causes Dog Seizures?

The first thing veterinarians will define is the catalyst for epileptic events. This is meant to define the origin of the episodes whether it be internal or external forces.

  • Structural seizures are due to primary brain disease (e.g. degenerative disease, brain tumor, stroke).
  • Idiopathic epilepsy is subdivided into proven-genetic (breed-related), suspected-genetic, and epilepsy of unknown origin.
  • Reactive seizures are due to metabolic, systemic or other non-primary brain disease.

In many cases seizures are caused a combination of underlying conditions and external factors:

  • Kidney disease
  • Liver disease
  • Vascular disease
  • Embolism
  • Traumatic injury to the head
  • Electrolyte imbalance
  • High or low blood sugar
  • Anemia
  • Encephalitis
  • Poisoning

Breeds Prone to Epilepsy

Breeds such as Australian Shepherds, Beagles, Belgian Tervurens, Border Collies, Collies, German Shepherds, Labrador Retrievers, Cavalier King Charles Spaniels , Dachshunds , English Springer Spaniels , Finnish Spitz , Irish Wolfhounds , Lagotto Romagnolos , Petit Basset Griffon Vendeens , Shetland Sheepdogs , Standard Poodles and Vizslas are more genetically predisposed to experiencing seizures than other breeds.

Types of Seizures

According to the International Veterinary Epilepsy Task Force , there are three main types of seizures in animals:

  • Generalized Seizures
  • Myoclonic Seizures
  • Focal Seizures

Generalized Seizures

This class of seizure is often known as a Gand Mal seizure. They involve both cerebral hemispheres, and usually result in a loss of consciousness.

Myoclonic Seizures

Similar to generalized seizures, but does not usually result in unconsciousness. These seizures are typically caused by stimuli like light or sound. They can also be a result of underlying structural damage in the brain.

Focal Seizures

Focal seizures usually do not result in unconsciousness. They typically only affect one hemisphere in the brain and present as subtle changes in behavior, like twitching, absent-minded chewing or loss of balance. Focal seizures often precede more serious degenerative patterns that cause more generalized seizure activity.

According to Dr. Michelle Carnes, “Our [epileptic] patients may experience focal seizures prior to developing generalized seizures; they just probably go unnoticed,”

An Alternative to Phenobarbital…

CBD from a full-spectrum hemp extract!

Since hemp became federally legal in 2018, a lot of research has been done to explore the efficacy of CBD as a treatment for epilepsy. Aside from thousands of anecdotal cases where seizures were treated with cannabis, we now have clinical research that confirms those findings.

In a 2017 double-blind study conducted by Colorado State University , 89% of dogs who received CBD in the clinical trial had a reduction in the frequency of seizures. Additionally, they saw a significant association between the degree of seizure reduction and the amount of CBD concentration in the dog’s blood.

This was not the only study to find CBD to be a successful anti-epileptic supplement for pets. Yamazaki University of Animal Health Technology in Japan conducted a similar experiment with great results.

In addition to these clinical trials, holistic pet cannabis expert, Angela Ardolino has treated hundreds of animals on her rescue, Fire Flake Farm.

In a recent interview, she talked about one of her rescue’s journey.

“We had an 18-year-old Chihuahua who had been experiencing multiple grand mal seizures a day, but 100 mg of the HEAL full spectrum hemp extract tincture from CBD DOG Health every day kept them at bay. Along with reducing her dementia, increasing her energy, focus and appetite”.

Daisie was fed a well rounded raw and fresh diet as well as getting daily applications of Soothe salve on her yeasty paws. With great pride Angela says, “After a month, you would hardly recognize this dog!”

Side Effects of Phenobarbital

When our pets have seizures the first thing we are concerned about is their safety and comfort. The last thing we want to do is cause them more discomfort or put them in danger, but with drugs like PB that is often the unintended consequence of long-term use.

Sedation

As we’ve discussed, the main way that phenobarbital works is by suppressing electrical energy in the brain. One of the clear results of this mechanism is it reduces the mental function of our pets. They are commonly reported to be tired, slow and almost depressed looking. Where quality of life is concerned, this is a big loss.

Excessive Hunger

Pet parents commonly see their dogs gaining a lot of weight while taking phenobarbital. Not only does this affect their quality of life, but it can also cause a domino effect in other areas of their health and well-being.

Excessive Urination

Polyuria, or excessive urination is caused by the increased thirst drive in dogs who take PB. When your dog or cat is taking this drug, it is not uncommon to find messes around the house.

Nausea/Vomiting

Especially in the beginning, many dogs who are treated with Phenobarbital experience vomiting and an upset stomach. Typically this diminishes after a couple weeks of treatment.

Neurotoxicity in Younger Animals

Phenobarbital is not recommended for younger animals as clinical research indicates it has neurotoxic effects and can be extremely detrimental to cognitive development. Suppression of brain function sounds bad for any animal, but it is especially detrimental to developing brains.

Liver Damage

One of the most significant side effects that dogs experience when treated with Phenobarbital is stress, and eventual damage to the liver. In most cases, long term damage occurs after the three months mark. It can start with scarring of the liver and end with significant loss of liver function, depending on how closely they are monitored by your veterinarian.

In the majority of dogs, a serum PB concentration between 25−30 mg/l is required for optimal seizure control. Serum concentrations of more than 35 mg/l are associated with an increased risk of hepatotoxicity and should be avoided.

Phenobarbital has been linked to raised levels of several liver enzymes that are used as markers to indicate liver damage (ALP, ALT, GGT). The significant anomalies in these levels indicate that the liver is working overtime to process the drug.

Side Effects of CBD for Dog Seizures

CBD is known for its high level of efficacy with seizure control as much as it is for the safety of its use. There is a significant amount of research that points to the safety of CBD as a way to help our pets, even at extremely high doses well above the normal recommended levels.

Many critics of CBD will point to one study which suggests that the use of CBD can lead to a rise in one particular liver enzyme, APL. According to experts in the veterinary field like Dr. Gary Richter DVM, this is not a significant rise and should be looked at as insignificant.

It is worth mentioning that there are multiple other studies which do not show any increase in liver enzymes like ALP for dogs treated with CBD from a full-spectrum hemp extract.

What we do know is that the minimal rise in liver enzymes from CBD is nothing compared to the significant levels seen in dogs treated with phenobarbital. CBD is not known to cause liver damage, but it is processed by the liver.

Phenobarbital Interactions With Other Drugs

Along with the numerous side effects and potential damage to the liver, Phenobarbital can have dangerous interactions with a long list of drugs. If you are using Phenobarbital for your dog, consider the limitations associated with its relationship to other treatments.

Avoid phenobarbital in combination with these drugs.

*Note* This is not an exhaustive list.

  • Corticosteroids
  • Cyclosporine
  • Metronidazole
  • Voriconazole
  • Digoxin
  • Digitoxin
  • Phenylbutazone
  • Some Anaesthetics
  • Cimetidine
  • Omeprazole
  • Lansoprazole
  • Chloramphenicol
  • Trimethoprim
  • Fluoroquinolones
  • Tetracyclines
  • Ketoconazole
  • Fluconazole
  • Itraconazole
  • Fluoxetine
  • Felbamate
  • Topiramate

CBD Interaction with Other Drugs

Though CBD’s interaction with other drugs still requires more clinical review, it is widely believed to be incredibly safe and stable with most commonly prescribed pharmaceuticals.

That being said, CBD is just one part of many in a complex relationship between compounds interacting in a full-spectrum hemp extract. Depending on the drug, it is possible that CBD may increase or decrease potency of another drug, or have no effect at all. It is always a good idea to consult with your holistic vet to find out how CBD may interact with drugs your pet is already taking.

Conclusion

When given the choice between Phenobarbital and CBD for the treatment of seizures, the most important thing to consider is quality of life. Our goal in the first place when trying to reduce seizure intensity and frequency is to make our dogs feel better.

The issue with so many of these conventional pharmaceutical drugs is you replace one problem with a whole set of others that can end up being even more detrimental than the ones you started with.

Though the effects may not be immediately as effective with a holistic approach, you can be confident that the effects will be better tolerated and more supportive of your pet’s wellness and longevity.

Can CBD Oil Help Dogs With Seizures?

Hello, everyone! This week I want to talk to you about CBD oil for dogs. Specifically, I would like to address how CBD oil could significantly help your dog with epilepsy.

Before going on with the article, I want to let you know as a Canine Behaviorist, I work closely with veterinarians, and highly recommend talking to a veterinarian before implementing CBD oil into your dog’s routine to ensure it’s the best solution for your individual dog (remember, all dogs are different).

I also highlight CannaCanine’s CBD oil in this article. I do not earn any commission on their sales, but I have received a handful of different CBD products for dogs and their product is by far the highest-quality product. I am so impressed with CannaCanine’s product I have taken them on as a client writing content for their organization.

With this said, let’s move on to the article.

Did you know one to five percent of dogs have a seizure disorder? This may sound like a small percentage, but when you think about how many dogs there are, that’s way too many.

Watching your dog have a seizure is frightening. You’re watching your dog go through a traumatic experience. You feel out of control, and you’re not sure what to do to help them if you’re not familiar with this condition.

If your dog has never had a seizure before, you should still understand what should be done in case of an episode. If you notice your dog experiencing a seizure, try to be calm (keep in mind your dog can ‘feel’ your emotions) and observe his surroundings to ensure there’s nothing in reach that could cause harm. You should also watch where your hands are. Your dog could accidentally bite you as he or she will not have control over his/her body during this time.

When we adopt our dogs, serious conditions like seizures aren’t usually our main concern. But, learning about everything that could affect our dogs and how to help is important.

If you’re unsure of what a seizure looks like, you’ll generally notice: collapsing, stiff muscles, jerking movements, loss of consciousness, foaming at the mouth, and/or a confused gaze. She might appear as if she’s looking out into space… as if she’s in another dimension.

After a dog has a seizure, she might have a hard time walking on her own. She may be disoriented. You might also notice her bumping into things she usually knows are there.

CBD has become popular in the dog world. Not only has CBD been found to help with seizures, but with pain, sleep, anxiety, skin problems, cancer, and digestive issues, too.

There are 2 Types of Seizures

There are two types of seizures a dog could have; symptomatic or idiopathic.

Symptomatic seizures are caused from an abnormality inside or outside of the brain. This could be from lead poisoning, encephalitis, or some sort of head trauma.

Idiopathic epilepsy doesn’t have a cause, though. Idiopathic epilepsy is thought to be genetic. Dog breeds who are commonly diagnosed with idiopathic epilepsy include English Springer Spaniels, Viszlas, Collies, Beagles, and Dachshunds. If you have one of the dog breeds prone to epilepsy, don’t worry yourself too much but just be sure to keep a watch for symptoms.

What’s the Best Way to Treat Seizures?

The medication that is prescribed to dogs with seizures has been found to help but may also come with heavy side effects including lethargy, long-term liver damage, and/or confusion.

One of the methods dog lovers are turning to instead of pharmaceutical medicine is Cannabidiol, or CBD. CBD oil is a non-toxic, natural, and effective form of treatment (of course, make sure you talk to your vet).

When you’re researching CBD and seizures in dogs, there are hundreds of positive testimonials. But, it comes as no surprise that CBD is met with controversy.

It’s important for you to understand CBD oil doesn’t make your dog ‘high’ like marijuana does. THC is responsible for the ‘high’ effect. And, there is little to no THC found in CBD oil.

If you’re a supporter of the medicinal effects of the cannabis plant, you may be asking why THC is not recommended for dogs. After all, we do recommend medicinal marijuana for humans who are experiencing serious medical conditions.

The reason. Dogs are extremely sensitive to THC. THC is the primary psychoactive component of a marijuana plant. Cannabidiol (CBD) is one of 113 compounds found in cannabis plants. The compounds, known as Cannabinoids, are natural and don’t contain any psychoactive properties or effects.

CBD with extremely low doses of THC may help dogs with seizures significantly, though. And, it has been found to be particularly helpful to dogs who are experiencing pain from cancer and/or seizures.

Dr. Stephanie McGrath is a veterinarian who specializes in neurology at Colorado State University. She is an advocate for CBD in veterinary medicine and is currently leading a clinical study on the treatment of epilepsy (which causes seizures). You can do your own research about her studies to see what she’s found if you’re interested in learning more about the effects of CBD.

CBD Dosage for Dogs

When you choose to use CBD oil for your dog with seizures, it’s important to start at the lowest dose possible. You can then increase the dosage if necessary.

The dosage of the CBD oil is also a discussion you could have with your veterinarian… especially if your dog is taking any other medications. You want to make sure the CBD oil won’t interact negatively with any medicine you’re dog has been prescribed.

The Side Effects of CBD

When you’re looking for a new medication for your dog, natural or pharmaceutical, you want to know the side effects.

CBD has no known side effects when administered on its own. However, CBD can have interactions with certain prescribed medication by inhibiting a family of liver enzymes, called cytochrome P450. This enzyme metabolizes more than 60 percent of the marketed medications we consume.

You can read more about CBD Drug Interactions on CannaCanine’s website. You’re able to look at a full list of medications metabolized by Cytochrome P450 3A4.

Testimonials Say it All

CannaCanine enjoys sharing testimonials so you’re able to hear real-world experiences about dogs who have used their products. Below, you will read a testimonial from CannaCanine about Blaise, a dog who was experiencing seizures, who had been prescribed pharmaceutical medication for treatment. His owner no longer wanted him to take phenobarbital… so she considered CBD oil. The CBD oil worked wonders on Blaise.

Please note, every dog is different and there’s no guarantee any medication, whether pharmaceutical or natural, will work the same for every dog. But, if you’re looking for alternatives, the research shows CBD oil may be worth considering … especially with the support from your veterinarian.

“Blaise started to experience seizures when he was just a year old. The seizures started to be mild and were few at the start. I thought nothing of it at first because they were so infrequent. When Blaise was around two and a half he started having partial seizures. These affected half of his body and he would suddenly tumble to the ground. This was absolutely horrifying to watch as they came often without warning.

To help combat his seizures I was recommended to give him phenobarbital. Phenobarbital is a common medicine given to dogs to help treat seizures. Several people told me to hold off on the phenobarbital treatments due to the ill side effects on dogs. I decided to wait before starting treatment to see if the seizures would return. By Blaise’s third birthday he finally had a full seizure. My worst fears had finally manifested!

Our vet immediately put Blaise on a high dose of phenobarbital for every 12 hours. Blaise became so drugged up that he would lose his balance and fall over. The worst of it was when he fell down twelve flight of stairs! I hated seeing him like this. His perky and fun personality was gone, replaced by lethargy and sadness. Blaise became a shell of the fun dog he once was.

A a nurse I had read articles on the beneficial effects of CBD oil on seizures. I started to research natural and alternative medicine for canines to learn more about CBD oil. At first I was cautious but decided to try it on Blaise. It was the best decision I could make! I was glad I ordered the CBD treatment. Despite the process of weaning him off of phenobarbital, the first dose of CBD oil made him more alert. Little by little, I got him off the phenobarbital.

Today, Blaise is seizure free and no longer taking phenobarbital. All thanks to CBD oil!”

Chat with Your Vet

I can’t emphasize this enough. Before implementing CBD oil in your dog’s routine, you should talk to your vet. If your dog is struggling with a medical condition, you want to make sure you have the dosage right. And, you also want to ensure your dog is a suitable candidate for CBD use.

If your veterinarian isn’t familiar with alternative medicine, you might consider contacting a veterinarian who specializes in it. You can find an alternative veterinarian by searching the American Holistic Veterinary Medical Association’s website.

CannaCanine is 100 percent organic and non-GMO, two qualities you should search for in any CBD oil to ensure maximum quality. CBD that isn’t organic could contain pesticides and herbicides, resulting in more harm than good for your dog.

CannaCanine only contains two ingredients- organic MCT Coconut Oil and Organic CBD Hemp Oil. This is another factor you should consider when searching for CBD oil for your dog. Generally, the more ingredients there are in the oil, the lower the quality of the oil.

Why is coconut oil included? That’s a great question. Coconut oil increases the absorbency of the CBD oil. And, it can work wonders for our dogs. Coconut oil can help with itchy skin, eczema, cuts, scrapes, wounds, and hot spots. And, on top of all of that, it’s a powerful anti-fungal, anti-bacterial, and anti-viral.

I couldn’t wait to try CBD oil for my dogs after learning all the benefits. And, for a limited time, CannaCanine is offering a special promotion.

This year is the Year of the Dog, and to celebrate, CannaCanine is offering you 30 percent off of your store purchase. If you decide this could be a good option for your dog, use code YEAR to take advantage of the sale.

If you have any questions, I am happy to answer them. Please feel free to contact me via AmberLDrake.org or at [email protected]

If you have any topics you would like discussed, I am open to suggestions here too. I want to make sure I’m answering all your questions.
