In this article, we will review the different types of seizures in dogs, and what they look like (with pictures and videos of dogs having these seizures).

Seizures can manifest in different ways in dogs, depending on the type of seizure. However, the most common is the grand mal seizure. With a grand mal seizure, your pooch usually starts acting confused before flopping on the ground and paddling uncontrollably. It may seem like your pal is dreaming, but jerking motions in a seizure are more pronounced. With a seizure, you may also see drooling, non-responsiveness, and involuntary urination or defecation.

What are the types of seizures?

Before we review pictures and videos of dogs having seizures, you should know that there are three major types of seizures in dogs:

  • Grand mal or general seizures are the most common type. The bursts of abnormal electrical activity are throughout the brain. It can cause unconsciousness and convulsions and usually lasts from several seconds to a few minutes.
  • Focal or partial seizures affect a part of the brain. You may see movement on one side of the body. They may only last a few seconds, or they may progress to a general seizure.
  • Psychomotor seizures are characterized by a few minutes of strange behavior such as biting at the air or chasing the tail. Every time, your dog will do the same thing if the seizure causes it.

How do I know my dog is having a seizure? (Signs by Seizure Stage)

We are often asked what seizures in dogs look like and what are the most common signs that a dog is having a seizure, or about to have a seizure. Grand mal seizures have three major phases. Below are the top signs you may observe in each phase:

1. Signs that your dog is about to have a seizure (Aural/pre-ictal stage: before the seizure)

Below is a video showing the typical behaviors of a dog before a seizure:

During the seizure, dogs usually demonstrate:

  • Falling over
  • Paddling or jerking of the limbs

Vocalization

  • Hypersalivation
  • Urination/defecation
  • Muscle twitching
  • Tongue chewing or chomping

3. Signs that your dog just had a seizure (Post-ictal phase: After the seizure)

In the minutes or hours after a seizure, you may notice your dog:

  • Acting confused or dazed
  • Acting disoriented
  • Staring into space
  • Sleeping
  • Temporarily blind
  • Eating voraciously

What do life-threatening seizures look like?

Whether a seizure is life-threatening depends on the type of seizure, its cause, and how long it lasts.

Type

The seizures that are most likely to become life-threatening are grand mal seizures and cluster seizures. Cluster seizures involve multiple seizures that occur close together with little to no recovery period between ictal phases. These events can cause hyperthermia and place a dangerously heavy strain on the organs.

Cause

Seizures can be life-threatening if they are caused by:

  • Brain injury/head trauma
  • Brain tumor
  • Organ failure
  • Low blood sugar
  • Toxins

Duration

Grand mal seizures that last longer than about 3 minutes can quickly become life-threatening. When generalized convulsions wrack the body this long, it causes the body temperature to rise sharply. The resulting hyperthermia can cause heat stroke.

Any time your dog shows labored breathing, sudden collapse, or pale gums due to a seizure, it’s also a life-threatening emergency.

What does a minor seizure look like?

Characteristics of minor seizures include:

  • Isolated or a single seizure
  • Short-lived, lasting only 1-2 minutes
  • No identified cause

If your dog has a minor seizure, don’t panic. Take steps to keep your pooch safe and as calm as possible. Record observations of your pal’s seizure. After the seizure, contact your veterinarian to schedule an exam.

What should I do if my dog just had a seizure?

After a seizure occurs, report the incident to your veterinarian. If it’s the first one, schedule an office visit. Otherwise, follow the doctor’s instructions.

How to help your dog at home

Immediately following a seizure, support your dog by:

  • Sit near your dog and talk to them in comforting tones. Resist the temptation to pet him so he won’t bite you out of confusion and fear.
  • Keep the environment calm and prevent loud noises.
  • Block access to stairs or other hazards.
  • Gently place damp, cool washcloths over his feet to help reduce his body temperature.
  • Wrap your dog in a blanket and comfort him if he tolerates it well.
  • Let your dog sleep but check in on him occasionally.
  • Provide access to food and water.

What should I expect when I take my dog to the vet?

The vet will begin with a history and an examination. Depending on his findings, he may also run diagnostic tests to determine the cause of the seizure or seizures.

History

Your veterinarian will want to ask questions about events before, during, and after the seizure.

BeforeDuringAfter
Changes in food, schedule
New supplements
New pets/humans
How dog was acting
Any loud sounds
Any bright lights  
When it started/finished
Length of seizure
Time of day
What symptoms/behavior you observed  
Behavior after seizure
How much did he sleep?
Was he hungry/thirsty?
How long to return to normal?

Examination

In the examination, your veterinarian will evaluate your pooch, check vital signs, and conduct a neurological evaluation. He’ll look for an indication of the underlying cause of the seizure.

Diagnostic Tests

Depending on the history and examination, your veterinarian will choose diagnostic tests.

  • Blood count and chemistry
  • Urinalysis
  • CT or MRI
  • Cerebrospinal tap

When is a seizure an emergency?

Seizures become an emergency when

  • The seizure lasts over 3-4 minutes
  • Your dog has a cluster of seizures in a short time (over 2-3 seizures in 24 hours)
  • You suspect your dog ate a toxic substance
  • Your dog shows labored breathing, collapses, or has pale gums

If any of these are true, get your dog to the emergency clinic immediately.

What are the treatment options for seizures in dogs?

Treatment depends on the cause and severity of the seizures.

When a dog has a seizure that can be linked to an infection, toxicity, or a metabolic cause, your veterinarian will treat the underlying condition. Dealing with the root cause may be enough to resolve your dog’s convulsions.

Dogs that experience minor seizures, focal events, or isolated episodes usually don’t require treatment. Your veterinarian will usually prescribe anticonvulsant medications if your dog has:

  • Over one seizure a month
  • Cluster seizures in which one seizure follows closely after another
  • Prolonged or severe grand mal seizures
  • A history of brain trauma or injury
  • Evidence of a brain lesion on advanced imaging
  • Severe disorientation in the postictal phase

The most common anticonvulsant drugs for dogs are potassium bromide and phenobarbital. Some newer drugs include Zonisamide and Levetiracetam. Some dogs may require a combination of treatments if they don’t respond to standard treatments.

What can I do to prevent my dog from having another seizure?

If your dog has a seizure, there are some holistic approaches you can take to try to reduce the risk of his having more events.

  • Don’t stop giving anticonvulsant drugs without your vet’s approval – sudden disruption of these medications can trigger seizures in some dogs
  • Avoid salty treats if your pup is on potassium bromide
  • Feed a ketogenic diet
  • Give MCT oil as a supplement
  • Identify and remove potential triggers for your dog’s seizures
  • Provide a peaceful home environment

What are some misconceptions that people have about seizures in dogs?

There are some common misconceptions people have about seizures in dogs, such as dogs may swallow their tongues and choke during a seizure. Below, we’ll look at some false beliefs and set the record straight.

Frequently Asked Questions

Are seizures painful for dogs?

No, seizures are not painful for dogs. However, some dogs may become disoriented and frightened during a seizure.

Is there a cure for seizures in dogs?

If the seizure is caused by an underlying condition, treating the root cause may resolve the seizures. However, with idiopathic seizures, there is no known cure. Symptoms can often be minimized with treatment and monitoring.

What does it cost to treat seizures in dogs?

When dogs need anticonvulsant medications to treat seizures, the drugs can cost several hundred dollars a year. The total expense depends on the specific drug, your dog’s size, and the frequency of doses.

What dog breeds have a higher incidence of seizures?

Idiopathic epilepsy usually has a genetic component. The breeds that are more likely to develop seizure include:

  • Beagle
  • Belgian Tervuren
  • Bernese mountain dog
  • English springer spaniel
  • Golden retriever
  • Irish wolfhound
  • Keeshond
  • Labrador retriever
  • Shetland sheepdog
  • Vizsla

What should I look for after my dog has a seizure?

Following a seizure, your dog may be disoriented and unsteady on his feet. Make sure there are no hazards like open stairs or water. When you take your pooch outside, use a leash and observe him for signs of diarrhea, vomiting, or incoordination. Also, track how long it takes your dog to recover and return to normal.

Can a focal seizure develop into a generalized seizure?

Yes, some focal seizures will progress to generalized seizures. When this happens, abnormal electrical activity spreads to the rest of the brain.
