Epilepsy in dogs: symptoms, possible causes and when to see the vet

Epilepsy in dogs describes repeated seizures that start in the brain, but not every dog seizure means epilepsy. The veterinarian must rule out toxins, metabolic changes, liver or kidney problems, brain disease and other causes before calling it idiopathic epilepsy.

Quick summary

What you notice	Why it matters	Next step
Episode with loss of awareness	It may be a generalized seizure.	Record a video if safe and book a vet visit.
First seizure in an adult or senior dog	Secondary causes become more important to investigate.	Seek veterinary advice soon, even if recovery looks complete.
Repeated or long seizures	They increase the risk of overheating, injury and status epilepticus.	Emergency care if it lasts over five minutes or repeats.

When it is an emergency

Seizure lasting more than five minutes.
Several seizures in one day or no full recovery between them.
First seizure, especially in puppies, senior dogs or sick dogs.
Possible toxin, trauma, fever, low blood sugar or breathing difficulty.
Rapid worsening, blue gums, very high temperature or prolonged unresponsiveness.

What to do during a seizure

Stay calm and time how long it lasts.
Move furniture or objects your dog could hit.
Dim lights and reduce noise or stimulation if you can do so safely.
Record a video if it is safe and does not delay care.
Watch for loss of awareness, leg movements, salivation, urination or stool.
When it ends, keep the environment quiet and call the vet if there are warning signs.

What not to do

Do not put your hand in the mouth: dogs cannot swallow their tongue and you could be bitten.
Do not try to hold the dog down forcefully.
Do not give food, water or human medication during the seizure.
Do not bathe or cool your dog suddenly unless a veterinarian tells you to.
Do not wait at home if the seizure lasts over five minutes or several seizures happen close together.

After the seizure

It is common for a dog to be disoriented, tired, hungry, thirsty, restless, wobbly or visually confused for a while. This postictal phase can last minutes or hours. If your dog does not recover, worsens, has another seizure or shows breathing difficulty, contact veterinary emergency care.

What the veterinarian may check

Detailed history and video of the episode.
Physical and neurological examination.
Blood work, glucose, electrolytes, liver and kidney function.
Medication, parasite product and toxin exposure review.
Advanced imaging or cerebrospinal fluid testing when needed.

What data to record

Date, time and exact duration of each seizure.
What happened before, during and after.
Whether there was loss of awareness.
Leg movements, salivation, urine, stool or vocalization.
What recovery looked like and how long it took.
Possible exposure to toxins, foods, plants or cleaning products.
Recent medication, parasite products or dose changes.
Video of the episode if you could record safely.
Temperature and environment if the weather was very hot.
Monthly frequency to judge treatment response.

An organized history helps the veterinarian see patterns, not just scattered memories. In Dogtorcito you can record each seizure with date, time, duration, video, possible triggers, medication given, recovery afterwards and notes for the clinic.
