Dog Seizures: What to Do During and After an Episode

Quick Answer: Act Promptly

A single, brief seizure (under 2-3 minutes) in a dog that has had previous seizures is monitored at home. A first-time seizure, a seizure lasting over 5 minutes, or cluster seizures require emergency veterinary care.

Seizures are one of the most distressing things a dog owner can witness. Understanding what to do in the moment -- and what questions to ask your vet afterward -- reduces fear and leads to better outcomes.

Most Common Causes

Idiopathic epilepsy (common)

Most common cause in dogs 1-5 years old. No underlying disease found. Managed with medication.

Toxin ingestion (moderate)

Xylitol, certain plants, prescription medications, pesticides. Often abrupt onset with other symptoms.

Low blood sugar (hypoglycemia) (moderate)

Especially in toy breeds and puppies. Seizures, weakness, collapse.

Metabolic disease (liver, kidneys) (rare)

Organ failure can cause neurological signs including seizures.

Brain tumor (rare)

More common in older dogs. New-onset seizures in a dog over 7 years old without prior history warrants MRI.

Wait, Act, or Emergency?

You Can Watch and Wait If:

  • Known epileptic dog, brief seizure (under 3 min), returns to normal -- contact vet same day

Call or Visit Your Vet If:

  • First-time seizure
  • Post-seizure state lasting more than 30 minutes
  • More than 2 seizures in 24 hours

Go to Emergency Vet Immediately If:

  • Seizure lasting more than 5 minutes (status epilepticus -- brain damaging)
  • Cluster seizures (multiple seizures back to back)
  • Seizure in a puppy
  • Known or suspected toxin ingestion

Frequently Asked Questions

What do I do during a dog seizure?
Stay calm. Keep the dog away from stairs, furniture edges, and water. Do not put your hands near the mouth -- dogs can bite reflexively. Time the seizure. Talk to the dog calmly. Turn off bright lights. After it ends, keep the dog quiet and warm while you call your vet.
Do dogs know they are having a seizure?
Dogs are unconscious and do not experience the seizure as it is happening. However, the post-ictal period (after the seizure) can involve confusion, blindness, hunger, and disorientation lasting minutes to hours.
Does every dog that has a seizure need medication?
Not necessarily. Dogs with infrequent seizures (less than once per month) may be monitored without medication. The decision depends on frequency, severity, and underlying cause. Your vet will guide this decision.

Is Your Dog an American Bulldog?

American Bulldogs have breed-specific health vulnerabilities. ABRA-registered dogs from health-tested lines have better documented health histories.
