What Causes Seizures In Dogs?

There are a variety of causes for dog seizures. If your dog has them often, he may have idiopathic epilepsy, a disorder in which unusual, uncontrolled bursts of electrical activity in your dog’s brain cause periodic seizures. While epilepsy is inherited, veterinarians aren’t entirely sure what causes it. Other causes include:

  • Eating something poisonous (see which foods and plants are toxic for dogs)
  • Electrolyte problems
  • Anemia
  • Low or high blood sugar
  • Liver disease
  • Kidney disease
  • Head injury
  • Encephalitis (inflammation of the brain)
  • Stroke
  • Heat stroke
  • Brain cancer (learn more about cancer in dogs)

Types Of Seizures In Dogs

Experts generally classify dog seizures into 3 main types.

Focal Seizures

A focal, or partial, seizure in dogs occurs in a small part of the brain affecting one limb, one side of the body or just the face. Focal seizures in dogs typically progress to grand mal seizures over the dog’s lifetime.

Grand Mal Seizures

Grand mal seizures in dogs affect both sides of the brain and the entire body. These types of seizures typically look like involuntary jerking or twitching in all 4 of the dog’s limbs and include dilated pupils and the loss of consciousness.

Focal Seizures With Secondary Generalization

This type of seizure starts as a focal (partial) seizure and then has a second phase of a grand mal seizure that affects the whole body.

Is My Dog Having A Seizure?

Dog seizures can be mild to severe and anything in between the two extremes. They can last anywhere from less than a minute to several minutes. Sometimes they can occur in clusters, where your pet will experience several seizures within 24 hours.

Classic seizures typically happen in 3 phases or stages. There are many manifestations of these stages, and not all dogs will act the same, but here are some of the common symptoms of each phase.

Pre-Seizure (Preictal) Phase

  • Hiding
  • Trembling
  • Anxiousness
  • Weakness
  • Staring off into space
  • Attention-seeking behavior

Seizure (Ictal) Phase

If the seizure is mild, your dog may not lose consciousness, and there may little to no limb stiffening or paddling.

  • Muscle twitching
  • Uncontrollable shaking
  • Collapsing
  • Stiffening
  • Loss of consciousness
  • Drooling
  • Chomping
  • Tongue chewing
  • Foaming at the mouth
  • Falling to the side and making paddling motions with their legs
  • Involuntary defecating or urinating

Post-Seizure (Postictal) Phase

  • Disorientation
  • Loss of balance
  • Fatigue or lethargy

How Serious Are Dog Seizures?

A single, isolated seizure is rarely dangerous; however, if your dog has cluster seizures (multiple seizures within a short period of time), or if a seizure continues for longer than a few minutes, it causes their body temperature to rise and hyperthermia (elevated body temperature) can develop, so it’s crucial to take your dog to your vet immediately.

Can A Dog Die From A Seizure?

Status epilepticus is a serious and life-threatening situation that requires immediate veterinary treatment. This condition is characterized by epileptic seizures that continue for more than 5 minutes, or by the occurrence of more than one seizure within a 5-minute period in which the dog doesn’t return to “normal” in between seizures. Unless intravenous anticonvulsants are given immediately to stop the seizure activity, the dog may die or suffer irreversible brain damage.2 

What To Do When A Dog Has A Seizure

Seizures are scary for dogs and owners alike, so it’s important for you to remain as calm as possible to care for your pup and remember these important tips.1

  1. Keep notes documenting your dog’s seizures, keeping track of the date, time, length, frequency and symptoms. This will help your vet determine if there’s a pattern to your dog’s seizures and give them important information about your dog’s symptoms.
  2. Video the seizure so you can show it to your vet later.
  3. Know that your dog is not in pain, even if he sounds or acts like it.
  4. Do not try to grab his tongue or touch his mouth, as dogs tend to chew during seizures and you could get bitten.
  5. Keep your dog away from stairs, to prevent him from falling and hurting himself further.
  6. Cushion his head and gently hold and comfort your dog until he begins to regain consciousness.
  7. Seizures that last more than 2-3 minutes can put dogs at risk of overheating. You can try cooling your dog by applying cold water, wet towels or an ice pack around the groin area, neck, paws and head. But it’s crucial to get your dog to a vet as soon as possible.

What To Do After Your Dog Has A Seizure

Always call your veterinarian or an emergency vet after your dog has a seizure, even if your dog seems to be acting normally. It’s of the utmost importance to try to find out what may be the underlying cause for your dog’s seizure. Questions your vet may have include:

  • When did the seizure symptoms start?
  • Have they changed?
  • How many times have you seen the seizures?
  • What is the frequency of seizures within a week or a month?
  • Are you aware of any consistent predisposing factors when seizures occur, like after eating, exercise, when sleeping, etc.?

Your veterinarian will most likely do bloodwork, urinalysis and possibly x-rays or other imaging. Based on the results, your veterinarian will be able to help you either diagnose the underlying cause or control the seizures with medications.

Treatments

Dog seizure treatment will vary depending on your vet’s diagnosis, and if there’s an underlying illness, like liver or kidney disease, that’s causing the seizures. But if your dog has epilepsy, your vet typically will prescribe a seizure medication to help control seizures.

Unfortunately, many vet-prescribed medications used to treat epilepsy and seizures, such as phenobarbital, potassium bromide, primidone and diazepam, cause serious side effects in some dogs. And even with medication, an estimated 30% of dogs with epilepsy continue to have seizures.1

All-Natural Remedies

Fortunately, there are some all-natural ways you can help ease your dog’s seizures but always consult with your vet before giving your dog any supplement or attempting to treat any condition on your own.

CBD For Dogs

Many dog owners report that all-natural CBD oil for dogs or CBD treats help ease seizure symptoms. CBD (Cannabidiol) is derived from the hemp plant but contains no THC, the compound that’s associated with the high you get from marijuana. Studies in humans have shown CBD to be quite effective in managing seizures in epileptics. And clinical trials are underway about its effectiveness in dogs.

Essential Fatty Acids

Some veterinarians recommend introducing fatty acids into a dog’s diet to help reduce the frequency of seizures. Omega-3 fish oil for dogs has many other health benefits, including supporting heart health, joints and the immune system.

Change Your Dog’s Diet

Sometimes diet changes can be effective in treating seizures. Several studies have shown a correlation between epilepsy and food allergies. Consider switching your dog to a hypoallergenic diet. Or you can transition from a low-quality commercial dog food to human-grade fresh meals you can have delivered to your home or even home-prepared meals — these diet changes can benefit your dog’s overall health.

Breeds With A Higher Incidence

Epilepsy can occur in all dog breeds, including mixed breeds. An estimated 2% to 5% of all dogs have epilepsy.

Breeds with a known or highly suspected genetic factor:

Improving Your Dog’s Health & Immune System

Whether your dog has epilepsy or not, your dog’s diet and intestinal health affect his whole body health. As we mentioned earlier, switching to a healthier diet can go a long way in improving your dog’s well-being.

You may also want to consider adding a daily dog probiotic to your dog’s diet. These all-natural supplements can do wonders to boost your dog’s immune system, as well as to improve his gut health.

Consider Pet Insurance

Some of the causes of dog seizures are quite serious. Things like brain tumors are expensive to treat. Pet insurance can help defray the costs of treatment and could provide the financial resources to save your dog’s life. But, you will need to sign up as soon as possible since it will not cover preexisting conditions.
