Common causes of seizures in dogs include idiopathic epilepsy (most frequent, unknown cause), toxins (antifreeze, pesticides, certain plants), metabolic issues (liver/kidney disease, low blood sugar), brain abnormalities (tumors, inflammation, trauma, infection), and even heatstroke. Age matters, with puppies often affected by congenital issues and older dogs by tumors, but epilepsy typically starts in young adult dogs (1-4 years).

What are the common causes of seizures in dogs?

The most common extracranial causes are hypoglycemia, hypocalcemia, hyperthermia, hypothyroidism, liver disease, or ingested poisons such as caffeine, chocolate. Intracranial causes of seizures are diseases that cause either structural or functional changes inside the dog's brain.

What's the best thing to do after a dog has a seizure?

If a seizure lasts longer than five minutes, it is considered a medical emergency, and you should seek immediate veterinary care.

What is the rule of 3 for seizures?

The "Rule of 3" for seizures refers to two different concepts: a medical guideline for defining seizure freedom (wait 3 times the longest prior seizure interval) and first-aid steps (Stay, Safe, Side). Medically, the "Rule of Three-To-Six" suggests waiting three times the typical seizure interval to confirm seizure freedom after an intervention, but potentially longer (up to six times) if seizure risk is high, while clinically, the 3 S's (Stay, Safe, Side) guide first aid: Stay with the person, ensure they are Safe, and turn them on their Side for breathing.
 

What is the 5 minute rule for seizures?

The "5-minute rule" for seizures means that if a seizure lasts longer than 5 minutes, it's a medical emergency requiring immediate 911 (or local emergency number) assistance, as prolonged seizures (status epilepticus) can cause brain damage. Always time the seizure, call for help if it exceeds 5 minutes, if another seizure starts without full recovery, if the person has breathing issues, is injured, pregnant, diabetic, or if it's their first seizure, as these also warrant emergency care.

What can be mistaken for a seizure in dogs?

Seizures in dogs can be mistaken for shivering, tremors, dreaming, or fainting (syncope), but key differentiators include a dog's awareness during the event (seizures often involve unconsciousness or disorientation), the nature of the muscle movements (convulsions vs. general trembling), and the trigger (activity for fainting vs. rest for seizures). Other culprits include vestibular issues (vertigo), sleep disorders, breed-specific movement disorders like paroxysmal dyskinesia, or even behavioral problems, making a video recording and vet consultation crucial for diagnosis.
 

Do dogs remember they had a seizure?

Common causes of seizures include brain injuries, infections, stroke, tumors, and genetic factors, while triggers often involve sleep deprivation, stress, alcohol/drug use or withdrawal, high fevers (especially in children), and certain medications, all stemming from abnormal electrical activity in the brain. While epilepsy is a primary cause, many seizures occur due to specific, often reversible, medical issues. 

Do seizures cause brain damage?
