During a seizure: Time it, clear nearby hazards, and keep hands away from the mouth. A seizure reaching five minutes, repeated seizures, or another episode before recovery needs emergency care. Contact your veterinarian after a first seizure even if it stops.
“Dr. Kraemer, my two year old bulldog Romeo had a seizure last week and it was terrifying to watch. I felt completely helpless. What do I do now, and is this going to be his life from here on?”
Watching a seizure is frightening. Awareness can vary with the type of event; keep the area safe and avoid handling your dog’s mouth. At two years old, idiopathic epilepsy is one possibility, but age alone is not a diagnosis. The work up comes first, because the causes that are treatable, liver disease and low blood sugar among them, look identical from the outside. Three practical things from here. Film the next one, even ten seconds, because what you describe and what I see on video are often two different events. Write down the date, the length, and how long he took to come back to himself, because that log helps your veterinarian decide whether medication is needed. And know your three emergency thresholds: a seizure reaching five minutes, repeated seizures, or serious breathing or recovery problems. Seek emergency veterinary care for any of these.
Seizures, Convulsions, and Epilepsy in Bulldogs
A seizure is an episode of abnormal electrical activity in the brain, not a diagnosis of its cause. Health issues such as infections, toxins, or metabolic disorders can cause seizures. Seizures are episodes of disturbed brain activity that manifest in various forms such as:
- Convulsions
- Sensory disturbances
- Loss of consciousness
Epilepsy may be idiopathic or associated with structural brain disease
Keep your Bulldog safe, time the episode, and contact your veterinarian. A prolonged or repeated seizure needs urgent care.
Bulldog Seizures and Epilepsy 5 MUST KNOW
- Not every seizure means epilepsy; other causes must be considered.
- Idiopathic epilepsy is one possibility; it is diagnosed after other causes are considered.
- New seizures in an older dog require assessment for brain disease and causes outside the brain.
- Bulldog idiopathic head tremors are seldom a result of seizure activity.
- Epilepsy is typically managed with medication, while treatment for other types of seizures depends on the underlying cause.
What is Bulldog Epilepsy (idiopathic Seizures)?
Epilepsy is a disorder characterized by recurrent, unprovoked seizures. Many Bulldog owners assume that epilepsy and seizures are the same thing, but epilepsy describes a recurring seizure disorder, not every seizure event.
While all epileptic conditions involve seizures, not all seizures indicate epilepsy.
How Does Age Affect the Investigation?
Age is one clue alongside the examination, history, and tests. Seizures in puppies, adult dogs, and seniors can have different causes. Do not assume that every young dog has idiopathic epilepsy or that every older dog has a tumor.
🚨Breeding bulldogs and French bulldogs with a history of epilepsy is strongly discouraged
Seizures and Episodes That Can Resemble Them
Seizures may be focal or generalized. Their cause is a separate question.
Head tremors and movement disorders can look similar; a video and veterinary assessment help distinguish them. See the guide to seizure-like episodes.
What Are Bulldog Head Tremors?
The “bulldog head shake” is often mistaken by owners for something more serious. While these sudden head-bobbing episodes can be startling, they’re typically harmless and seldom linked to seizures.
What Is Paroxysmal Dyskinesia (PD) in Pets
Paroxysmal dyskinesias are movement episodes that can resemble seizures. Awareness often remains normal, but that alone does not distinguish them from every focal seizure.
Dietary treatment is relevant only to selected diagnosed disorders; do not change diets to diagnose a seizure-like event yourself.
How Are Seizures Described?
Seizures are typically classified based on three key factors:
- Presentation: How do they appear or manifest? (e.g., full-body convulsions vs. subtle twitching)
- Duration: How long do they last? (a few seconds, several minutes, or prolonged episodes)
- Frequency: How often do they occur? (isolated incident, recurring, or in clusters)
#1 FOCAL vs. GENERALIZED SEIZURES:
- Focal seizures in bulldogs are often subtle and less dramatic, affecting only a specific part of the body, like a twitching limb or facial muscle, and can be easy to miss.
- Generalized seizures, on the other hand, are far more noticeable, involving the entire body with symptoms like
- full-body convulsions
- loss of consciousness
- and uncontrolled movements.
#2 STATUS SEIZURES vs. CLUSTER SEIZURES
- Cluster seizures: Multiple seizures within a short period, commonly within 24 hours; a dog may recover between them. Repeated seizures need urgent veterinary advice.
- Status epilepticus: A seizure reaching five minutes, or repeated seizures without recovery between them, is an emergency requiring immediate veterinary treatment.
🚨Continuous status epilepticus seizure requires immediate intervention!
What Causes Seizures in Bulldogs and French Bulldogs?
- Idiopathic epilepsy (unknown origin): This is likely the most common cause of seizures in young bulldogs and is most often associated with generalized seizures. The cause remains unknown, though there may be a genetic component.
- Hypoglycemia (Low Blood Sugar) Hypoglycemia is a more common cause of seizures in infants and young puppies, typically due to inadequate food intake or fasting. In mature bulldogs, seizures caused by hypoglycemia are rare and are usually linked to a rare pancreatic tumor that excessively secretes insulin.
- Toxins & Poison Exposure to various toxins and poisons can also lead to seizures.
- Metaldehyde (snail bait)
- Lead
- Organophosphates ( weed killers)
- Pyrethrin’s (used in insecticides)
- Brain tumors are more common in aging bulldogs and rare in younger dogs.
- Head Trauma A physical injury to the head can lead to acute seizures.
- Heat Stroke Overheating in Bulldogs, especially during hot weather or excessive exercise, can trigger seizures.
- Liver Disease Liver conditions such as a liver shunt (portosystemic shunt, PSS) can be congenital or acquired, like portal hypertension.
- Viral, Infectious, and Inflammatory Diseases Certain diseases, like canine distemper and rabies
Seizures Symptoms in Bulldogs and French Bulldogs
There is a significant difference in seizure manifestation when comparing focal to generalized ones
#1 BULLDOG FOCAL SEIZURES:
Focal seizures, also known as partial seizures, affect only one part of the brain and can result in more localized symptoms. Common behaviors associated with focal seizures include:
- Fly-biting behavior: A movement that looks like the dog is snapping at flies when no flies are present.
- Focal twitching: Twitches that occur in one area or side of the body without affecting the whole body.
#2 BULLDOG GENERALIZED SEIZURES
Generalized seizures involve multiple regions of the brain and cause symptoms that affect the entire body. These seizures are typically more severe and include:
- Generalized tonic-clonic seizures: characterized by stiffening of the body (tonic phase) followed by rhythmic jerking (clonic phase).
- Incontinence: loss of control over the bladder and bowels during the seizure.
- Teeth chattering: rapid clattering of teeth, which can be accompanied by other facial muscle spasms.
- Recumbency with leg paddling: The dog may lie down and move its legs as if running or cycling.
- Loss of consciousness: The dog may appear unresponsive or dazed.
- Stiffness: generalized muscle rigidity across the body.
- Vocalization: making noises, which may include barking or crying out, usually due to disorientation or distress.
The Three Stages of Seizure and Epilepsy in Bulldogs:
Understanding the stages of a seizure may help bulldog owners better manage and respond to these episodes. Seizures generally have three distinct phases:
Stage 1: BULLDOG PRE-SEIZURE (Aura)
The aura is the initial stage where your bulldog might sense an impending seizure. This phase serves as a warning that a seizure is about to begin. Signs to watch for include
- seeking extra attention
- appearing restless
- exhibiting unusual behavior.
Stage 2: BULLDOG ACTIVE SEIZURES (Ictus)
The ictus is the seizure event itself. This phase can last from a few seconds to several minutes.
Stage 3: BULLDOG POST-SEIZURES (Post-Ictal)
Following the seizure, during the post-ictal phase, your bulldog may seem
- confused
- disoriented
- do not recognize familiar surroundings or people
- impaired coordination
⚠️ This phase duration can vary from a few minutes to several hours.
When Should I Seek Veterinary Help For My Bulldog Seizure?
It is crucial to seek veterinary care for seizures that
- reach five minutes, or do not stop as directed in your prescribed rescue plan
- for repeated cluster seizures within the same day
- if your bulldog experiences a prolonged post-ictal recovery.
How to Care for Your Bulldog During a Seizure?
Caring for a bulldog during a seizure involves ensuring safety and closely monitoring the situation. Here are some practical steps to follow:
#1 Create a Safe Environment:
- Clear nearby hazards and block access to stairs without restraining your dog or reaching near the mouth.
- Use pillows, carpets, and blankets to cushion any potential blows to the head and body.
#2 Optimal Head Positioning:
- Check the head position to ensure it is safe and clear from any objects.
- Trying to touch the mouth could result in bites.
#3 Adequate Monitoring:
- Note the duration and frequency of the seizure. This information is crucial for your vet to understand the severity and pattern of the seizures.
- Have an adult stay close to or sleep near your bulldog
#4 Use of Alarming Accessories:
Attach a bell to your bulldog’s harness or collar. This may help alert you to any movements that might indicate the start of a seizure, especially during the night. 🔔
#5 Watch for Accidents:
Observe for any unusual urine or fecal accidents, which might indicate a seizure occurred when you were not present.
#6 Documentation & Recordings:
- If possible, take a video of the seizure event. This can provide your veterinarian with valuable information for diagnosis and treatment.
- Note any specific symptoms or behaviors you observe during the seizure.
#7 Do Not Delay Emergency Care
Prolonged seizures can cause dangerous overheating. Call an emergency veterinarian and follow their transport instructions. Do not delay care to take a temperature or force anything into the mouth.
How Bulldog Seizures and Epilepsy Are Diagnosed?
Medical exam:
- pet’s age
- video of the event when possible
- timesheet duration of the event
- history of past events
- toxins or poisons in and around the house
Blood test: including
- blood sugar
- liver enzymes
- and a bile acid test
Radiograph and ultrasound: abdominal for liver size MRI, CAT Scans for suspected brain injuries and tumors Spinal Fluid for suspected central nervous system disease Nuclear scintigraphy for liver shunt
Reducing Avoidable Seizure Risks and Managing Epilepsy
- Annual Blood screenings
- Vaccination, including distemper and rabies
- Protect your house and environment from toxic material and poison
How to Treat Bulldog and French Bulldog Epilepsy and Seizures?
The treatment approach for bulldog seizures depends on the underlying cause. Here are some common treatment options:
#1. SEIZURES DUE TO LIVER DISEASE TREATMENT:
- Liver shunts can often be surgically repaired.
- When surgery is not an option, medical management may involve dietary changes and medications to support liver function.
#2. SEIZURES DUE TO LOW SUGAR TREATMENT:
- Bulldog puppies with hypoglycemia may require short-term intravenous treatment with glucose and proper feeding
- For adults with insulinoma, surgery might be necessary to remove the tumor.
#3. EPILEPSY SEIZURES IN BULLDOGS TREATMENT:
Veterinarians may select phenobarbital, potassium bromide, levetiracetam, zonisamide, or another antiseizure medicine. The choice depends on the seizure pattern, health conditions, other drugs, and monitoring needs. These medicines are not interchangeable.
Phenobarbital can cause adverse effects and is unsuitable for dogs with certain liver disease. Ask about blood tests and drug-level monitoring. Do not change or stop prescribed medication yourself. A home rescue medicine should be used only under a specific veterinary plan.
Seizure Monitoring in Bulldogs and French Bulldogs
Some medications, like phenobarbital, require regular monitoring of blood levels and liver enzymes to ensure efficacy and safety. Based on these results, dosage adjustments may be required.
Bulldog Seizure and Epilepsy Supportive Care:
Supportive care is essential alongside medication; this includes maintaining
- a safe environment
- proper nutrition
- reviewing any supplements with the prescribing veterinarian
- regular veterinary checkups
What Are The Best Supplements For Dogs Seizures and Epilepsy?
Many of you already give your Bulldog preventive-care supplements, such as multivitamins, joint and bone formulas, immune support, and probiotics.
If your dog develops seizures, review the entire supplement list with your veterinarian to make sure it fits the diagnosis and current medications.
Your veterinarian may recommend continuing some products, adding selected supplements, or temporarily stopping others.
Think of it as checking the whole team’s playbook: everything your Bulldog takes should work together.
Omega-3 fish oil has been studied for potential neurological benefits in dogs, although the evidence varies. Other supplements, including magnesium and melatonin, could be considered under veterinary guidance.
Supplements should support the treatment plan, never replace veterinary medical management and prescribed seizure medication.
What is The Prognosis for Seizures and Epilepsy in Bulldogs
Watching your bulldog puppy experience an epileptic event can be frightening and may seem painful or even life-threatening. Prolonged or repeated seizures can be life-threatening, even when the dog has previously done well on treatment. Many dogs achieve useful seizure control, but outlook depends on the cause, frequency, severity, and treatment response. Some need ongoing adjustments or specialist care. 
⚠️ On the other hand, the prognosis for non-epileptic seizures varies depending on the underlying cause and is determined on a case-by-case basis.
Insider tip
My bulldog’s head bobs and shakes. Is that a seizure?
What do I actually do while it is happening?
When is it an emergency?
Why does my bulldog’s age change the answer?
What will the work up involve?
Is he on medication for the rest of his life?
Can seizures be prevented?
Epilepsy is managed with prescription medication chosen and monitored by your veterinarian, and there is no supplement that takes its place. I want that said before anything else, because this is a condition where owners are sold hope. In one survey of owners of epileptic dogs, nearly half were giving a supplement and the great majority believed it was reducing seizures. For most of those products there is no trial support for that belief at all.
The warning on this page is worth more to you than anything in my store. If your dog is on potassium bromide, changing his food, his treats or his salt intake can move the drug level in either direction, which means losing seizure control or drifting toward toxicity. So tell your veterinarian before you add anything, including anything from me. That applies to a diet change as much as a supplement.
There is one real and well documented problem where ordinary care does help: the weight. Phenobarbital and bromide both increase appetite. When researchers compared 222 dogs with epilepsy against more than seven thousand healthy dogs, the medicated dogs were hungrier and carried more weight, and their owners were already working harder at restricting food than other owners were. That tells you ordinary effort often is not enough. Measured meals rather than a full bowl, counting the treats, and keeping him moving are the useful responses. On a restricted ration, a daily multivitamin may help cover what a smaller portion no longer supplies, and the pre and probiotic chews may help a dog whose stomach is unsettled, which is common on bromide. Whether either suits your dog is a question for the veterinarian who is managing his medication.
Two things I will not claim, because the evidence is not there. Liver supplements are widely sold for dogs on phenobarbital. There is no study in dogs showing that any of them protects the liver from it. What catches a liver problem early is the recheck blood panel, so keep the rechecks rather than buying reassurance. And medium chain triglyceride oil, which you may have read about, does have real trials behind it, but as an addition alongside medication, with a modest average effect and only a minority of dogs responding meaningfully. It is a conversation to have with your veterinarian, and I do not sell it.
Veterinary Care and Supportive Products
A first seizure always earns a veterinary examination, and a seizure that reaches five minutes, repeats within the same day, or is followed by a prolonged recovery is an emergency rather than an appointment. Store products are not established treatments or preventives for epilepsy. If your veterinarian recommends nutritional support for a separate need, review the ingredients alongside your dog’s medicines before shopping.
