Seizures in Dogs: 5 Dangerous Causes Every Owner Must Know

In addition to being alarming, sudden seizures in dogs may indicate a major medical issue. Abnormal electrical activity in the brain causes seizures, which manifest as drooling, paddling movements, shaking, collapse, or loss of consciousness. Because prolonged seizures can cause brain damage, respiratory problems, or potentially fatal complications, early veterinarian care is crucial. 

What are seizures in dogs

Dog seizures are caused by an abrupt spike in aberrant brain activity. The intensity and length of symptoms may differ depending on the part of the brain that is impacted.

Dogs often exhibit the following symptoms of neurological episodes:

• Abrupt collapse
• Jerking or trembling of the body
• Leg motions while paddling
• Foaming or drooling in the mouth
• Diminished awareness
• Twitching of the muscles
• Short-term disorientation following the seizure

Not all involuntary movements, though, are neurological episodes. Sometimes, shivering, trembling in the muscles, or even active dreaming while you’re asleep can be confused with seizures.

If your dog has a seizure, get medical attention right once, especially if it occurs abruptly or frequently. Epileptic episodes may get worse and raise the possibility of irreversible brain damage if treatment is not received. 

What Causes Sudden Seizures in dogs

• Epilepsy

One of the most frequent causes of repeated seizures in dogs is epilepsy. Over time, seizures result from this neurological condition’s recurrent aberrant electrical activity in the brain.

After eliminating other potential medical issues, veterinarians typically diagnose epilepsy. Anti-seizure drugs may occasionally be recommended to assist regulate the frequency and intensity of abnormal brain activity. 

• Dogs Brain Tumor
  

Brain tumours may trigger abnormal brain activity by placing pressure on the brain tissue. These tumours can be benign or malignant and are more commonly seen in older dogs.

Fortunately, depending on the type and location of the tumor, some dogs may make a full recovery following surgical removal.

• Metabolic Disorders

Dogs may also experience seizures due to certain liver or kidney conditions. Toxins can accumulate in the bloodstream due to conditions such liver shunts, which can impair brain function and cause seizures.

Furthermore, hypoglycemia, or low blood sugar, is another prevalent metabolic disorder associated with epileptic episodes, particularly in small breed dogs and puppies.

• Brain Abnormalities

Brain abnormalities, such as an excess of fluid in the brain, are the cause of structural epileptic episodes. For instance, a puppy may have a liver shunt or have an abnormal brain structure. Infectious diseases like canine distemper or toxoplasmosis, which is brought on by a parasite, can also induce seizures in puppies.

• Breed and Age Group Susceptibility

Some dog breeds have a genetic predisposition to seizures. Among these breeds are:

• Beagles
• Golden Retrievers
• German Shepherds
• Boxers
•  Poodles
• Miniature Schnauzers
•  Saint Bernards
• Cocker Spaniels\

In the meantime, age-related neurological disorders may also make epileptic episodes more frequent in older dogs.

Why are seizures in dogs dangerous?

While some neurological episodes could only last a few seconds, others might go on for several minutes. Long-term seizures can lower the brain’s oxygen supply and raise the possibility of irreversible brain damage.

Most significantly, if emergency veterinary care is not provided, multiple seizures within a brief period of time may rapidly become life-threatening.

What Should You Do During Dog Seizure?

• Try to be composed and concentrate on keeping your dog safe if they have a seizure.
• The following are crucial actions you should take: 
• Keep furnishings and potentially harmful items away from your dog.
• Keep your dog away from sharp edges and staircases.
• Keep your hands away from your dog’s mouth.
• If at all feasible, note how long the seizure lasted.
• To lessen stress, keep other pets away.
• Get in touch with a veterinarian. 

Owners of pets may occasionally attempt to halt the seizure by stroking, restraining, or misting the dog with water. This should be avoided, though, as it could lead to unintentional harm or raise stress.

Veterinary evaluation is still highly advised even if the seizure lasts less than a minute.

When Is a Seizure an Emergency?

• The duration of the seizure exceeds five minutes.
• Your pet experiences several seizures in quick succession.
• After the seizure stops, they do not get better in a few minutes.
• They appear feeble and unresponsive, or they have trouble breathing.
• They have never experienced a seizure before

How Veterinarians Treat Seizures in Dogs?

Long-Term Medication

To lessen the frequency and intensity of seizures, dogs with epilepsy frequently need daily medication for the rest of their lives.

• Typical Drugs: The following are the most widely used anti-seizure drugs (AEDs):
• One popular first-line treatment is phenobarbital. Frequently used, levetiracetam (Keppra) frequently has less early side effects.When treating refractory instances, potassium bromide (KBr) is frequently used in conjunction with other drugs. Another choice for controlling seizure activity is zonisamide.

Emergency Care

If a dog experiences cluster seizures or is in status epilepticus (seizing for longer than five minutes), diazepam or midazolam are administered intravenously or rectally to cease the activity very far away.

Monitoring and Adjustment

Frequent blood tests are essential for tracking drug levels and organ health, particularly with phenobarbital. This enables dosage modifications to reduce adverse effects, such as ataxia and sleepiness.

Treatment Restrictions

Although drugs control seizures, they cannot stop them, and fewer than half of dogs receiving treatment attain total seizure independence. 

When to visit a veterinary hospital

Dog seizures should never be disregarded, particularly if they occur frequently or abruptly. Your dog’s quality of life can be enhanced and major issues can be avoided with early diagnosis and treatment. Visit Starlight Veterinary Hospital care for a thorough assessment and monitoring if your dog has a seizure.

Depending on the dog’s condition, treatment may include:

• Immediate medication to stop or control seizure activity
• Oxygen support and continuous monitoring if needed
• Intravenous (IV) fluids to maintain hydration and stabilise the patient
• Blood tests to identify issues such as low blood sugar, toxin exposure, infections, or metabolic abnormalities
• Advanced imaging such as X-rays or CT scans if neurological conditions are suspected

Once the patient is stabilised, our veterinarians work to determine the root cause of the seizure episode. Since seizures can be triggered by conditions ranging from epilepsy and toxins to organ disease or brain abnormalities, treatment plans vary for every patient.

Early veterinary intervention can make a significant difference, especially for first-time seizures, prolonged episodes, or repeated seizure activity.
