Seizures in German Shepherds can be caused by genetic factors, with some breeds being more susceptible due to their genetic makeup.
Idiopathic epilepsy is a common cause of seizures in German Shepherds, accounting for about 80% of cases.
Symptoms of seizures in German Shepherds can vary, but common signs include confusion, loss of coordination, and foaming at the mouth.
Seizures can be triggered by stress, fatigue, or certain medications, making it crucial to monitor your German Shepherd's environment and health closely.
Causes and Symptoms
German Shepherds are at a higher-than-average risk for developing primary epilepsy, which means the underlying cause of their seizures is unknown. This breed-specific risk is likely due to genetics.
Seizures in German Shepherds can be caused by various factors, including hypoglycemia, hypocalcemia, and head trauma, which can lead to structural or functional changes in the brain.
The symptoms of seizures in German Shepherds can vary depending on the type of seizure. In partial or focal seizures, symptoms may include hallucinations, hackles standing on end, dilated pupils, and issues with mobility and coordination. In generalized seizures, symptoms may include muscle contractions, jerking, or a sudden collapse and loss of consciousness.
Here are some common symptoms of seizures in German Shepherds:
- Repetitive licking
- Facial twitching
- Snapping at the air
- Repeatedly kicking one leg
- Repeated twitching of the lip, eyelid, and/or ear
These symptoms can be an indication of a seizure, and it's essential to seek veterinary attention if your German Shepherd is exhibiting any of these behaviors.
What Causes?
Seizures in dogs can be caused by a wide range of factors, from internal health issues to external toxins.
Epilepsy is the most common cause of seizures in dogs, affecting between 2% and 5% of dogs. It's a condition that can be challenging to diagnose, especially in young dogs.
Some breeds are more prone to developing primary epilepsy, which means the underlying cause of the seizures is unknown. These breeds include Schnauzers, Basset Hounds, Collies, and German Shepherds.
Intracranial causes of seizures, which originate within the brain, can be caused by genetic epilepsy, trauma to the brain, tumors, nutritional imbalances, autoimmune disease, or infectious diseases such as canine distemper virus (CDV) and rabies.

Extracranial causes of seizures, on the other hand, can be caused by hypoglycemia, hypocalcemia, hyperthermia, hypothyroidism, liver disease, or ingested poisons such as caffeine and chocolate.
Here are some common causes of seizures in dogs:
- Infection or inflammation of the brain
- Cancer affecting the brain
- Head trauma
- Hypoglycemia (low blood sugar)
- Liver disease
- Hypocalcemia (low blood calcium levels)
- Kidney failure
- Low blood oxygen levels
- Lead toxicity
- Organophosphate toxicity
- Mycotoxins from fungi
- High levels of caffeine exposure
- Exposure to certain recreational drugs like methamphetamine
- Antifreeze poisoning
- Hydrocephalus (buildup of fluids in brain cavities)
- Portosystemic shunt (a congenital blood vessel abnormality)
- Heatstroke
Some causes of seizures are more common at certain life stages than others. For example, hydrocephalus and hypoglycemia typically affect puppies, while brain cancer is more commonly diagnosed in older pets.
What Are Symptoms of?
Seizures in dogs can be a scary experience, but recognizing the symptoms is key to getting your furry friend the help they need. Some symptoms are more noticeable than others.
Partial or focal seizures only affect a distinct region on one side of the brain, and symptoms can include hallucinations that lead the dog to snarl at nothing or bite at the air.
Generalized seizures, on the other hand, affect both sides of the brain and are more noticeable, causing muscle contractions, jerking, or a sudden collapse and loss of consciousness.
Dogs with focal seizures may exhibit strange behavior, such as hackles standing on end, dilated pupils, or sudden issues with mobility and coordination.
If your dog begins to show signs of a seizure, try to think back to what they were doing right before the seizure began and notify your vet.
Here are some common symptoms of generalized seizures:
- Pre-ictal phase (aura): unusual sights, smells, or other sensations
- Ictal phase: tonic-clonic seizures with muscle contractions and jerking
- Post-ictal phase: dull, lethargic, restless, unsteady on their feet, or temporarily blind
- Generalized tonic seizures: stiffness without paddling
- Generalized clonic seizures: paddling without stiffness
- Generalized seizures without stiffness or paddling: loss of consciousness
- Repetitive behaviors: licking, facial twitching, snapping at the air, kicking one leg, or twitching of the lip, eyelid, and/or ear
Health Issues and Risks
German Shepherds are at a higher risk of experiencing seizures due to their breed characteristics. Some German Shepherd owners may have noticed their dog's increased sensitivity to stress or anxiety.
Certain breeds, including German Shepherds, are more prone to seizures. These include large herding and retriever dogs, such as Labrador and Golden Retrievers. Bull Terriers can also be affected by an inherited form of epilepsy.
If your German Shepherd is experiencing a seizure, it's essential to act quickly. Seizures lasting longer than 3 minutes or multiple seizures in a row can be life-threatening and require immediate veterinary attention.
Prone to Certain Health Issues
Some dog breeds are more prone to certain health issues than others. German Shepherds, Australian Shepherds, and Labrador and Golden Retrievers are at a higher risk of experiencing seizures due to their large herding and retriever nature.
Seizures can be a significant concern for these breeds, and owners should be aware of the signs and symptoms. Large herding and retriever dogs are more susceptible to seizures, which can be triggered by various factors.
Bull Terriers, on the other hand, can inherit a form of epilepsy that leads to behaviors such as tail chasing, irrational fear, and unprovoked aggression. This inherited condition can have a significant impact on a dog's quality of life.
Breeds with short, flat noses, such as Pugs, Boston Terriers, and English Bulldogs, are more prone to breathing difficulties and other respiratory issues. This is due to the unique structure of their nasal passages.
Here is a list of dog breeds that are more prone to seizures and other health issues:
- German Shepherds
- Australian Shepherds
- Labrador and Golden Retrievers
- Bull Terriers
- Pugs
- Boston Terriers
- English Bulldogs
Are Fatal to Me?
If your dog may be having a seizure due to poison, contact your primary veterinarian or emergency vet right away.
Seizures lasting for more than 5 minutes could cause serious permanent brain damage.
If your dog has had a seizure lasting longer than 3 minutes, contact your primary veterinarian or emergency vet right away.
Multiple seizures in a row are a cause for concern and warrant immediate attention from a veterinarian.

Metabolic Disorders
Metabolic disorders can cause seizures in dogs, often due to a buildup of toxins in the bloodstream. Liver shunts, where the blood vessels in the liver aren't connected properly, can lead to seizures in puppies and older dogs.
This condition can be surgically repaired to prevent future seizures. Hypoglycemia, or low blood sugar, is another common metabolic disorder that can cause seizures in dogs.
Blood sugar levels can drop suddenly, triggering a seizure. Proper nutrition and regular feeding schedules can help prevent hypoglycemia.
Diagnosis and Treatment
If your German Shepherd has a seizure, it's essential to take them to the vet as soon as possible. The vet will perform a thorough health history, physical exam, and neurological exam to determine the underlying cause of the seizure.
Blood work, urinalysis, fecal exam, and specialized laboratory tests may be necessary to rule out underlying health problems. In some cases, a sample of cerebrospinal fluid (CSF) may be taken for analysis, or an MRI or CT scan may be ordered.
Seizures in German Shepherds can be treated with anti-seizure medications, such as phenobarbital, potassium bromide, or newer medications like zonisamide and levetiracetam. Combination therapy may be used if the dog responds poorly to standard treatments.
Diagnosing
Diagnosing seizures in dogs is a crucial step in determining the underlying cause of the seizure.
The diagnostic process starts with a thorough health history, a physical exam, and a neurological exam.
Your veterinarian will need to look for any underlying health problems that could have caused the seizure.
A detailed description of what happened during and after the seizure is essential in helping your veterinarian determine the cause.
Take a short video of your dog seizing if possible, as this can provide valuable information for your veterinarian.
Blood tests will be performed to determine if a metabolic disorder is causing the seizures.
A bile acid test may also be done, where the dog is fasted, given food, and has their blood tested two hours later.
Treatment Options
Medications are a common treatment for seizures in dogs. Phenobarbital and potassium bromide are two relatively inexpensive first-line treatments that can help reduce the severity and frequency of seizures.
Some dogs may require combination therapy, where multiple medications are used together to achieve better results. This is often the case when a dog responds poorly to standard treatments.
Veterinarians may prescribe medications like zonisamide, levetiracetam, gabapentin, and pregabalin (Lyrica) if first-line treatments are ineffective. These medications can be used alone or in combination with other medications.
