Seizures in dogs: first aid, emergency timing and recovery

What to do now

Start a timer and clear hazards. Call an emergency vet if a seizure lasts longer than two minutes, if another occurs within 24 hours, or if the dog does not regain consciousness between episodes. A seizure reaching five minutes is a critical emergency; do not wait until then to seek help. Call immediately for suspected poisoning, breathing difficulty or serious injury.

Keep children and animals away, dim lights and reduce noise. Do not restrain, shake or put anything in the mouth. Follow the vet’s instructions about transport during an active seizure. Contact your vet after a first brief seizure even if recovery seems complete.

Emergency? Call a vet now

Know what a seizure may look like, how to keep your dog safe, when to call urgently and what investigations may involve.

Veterinary help in your selected country

Phone your usual vet; their recorded message should explain out-of-hours arrangements. If unavailable, contact a local emergency veterinary hospital. Confirm that it can receive your dog before travelling if possible; do not delay urgent care. Human emergency numbers are not veterinary helplines.

Understanding the signs

A seizure is an episode of abnormal electrical activity in the brain. A generalised seizure may involve loss of awareness, stiffening, paddling, drooling and loss of bladder or bowel control. A focal seizure can affect one area, such as facial twitching, with less obvious loss of awareness. Trembling while alert can have other causes, including pain or cold; fainting and balance disorders can also resemble seizures.

A video is useful only when safe and without delaying care. One seizure does not automatically mean epilepsy.

Possible causes

Recurrent seizures may result from idiopathic epilepsy, where other explanations are excluded. They can also accompany low blood glucose, liver or other metabolic disease, toxins, head injury, brain inflammation or a structural brain problem. Age, history, examination and test results help distinguish possibilities. A new seizure in a puppy, an older dog or an unwell dog deserves particularly careful assessment rather than assuming a familiar epilepsy pattern.

Safe practical steps

Move nearby furniture away and block access to stairs or water without putting yourself in reach of the jaws. Do not try to hold the tongue: dogs do not need their tongue pulled out during a seizure. Avoid wrapping the dog in blankets, because overheating is possible. After the movements stop, allow quiet recovery in a safe floor-level space.

Confusion, pacing, temporary difficulty seeing, hunger or tiredness may follow; avoid crowding or startling the dog, who may bite unintentionally. Do not offer food, water or oral medicines until fully alert and swallowing normally. Use emergency medicine only if prescribed for that dog and exactly according to the individual plan.

What the vet may do

The vet will ask about duration, awareness, movements, recovery, previous episodes, medicines and access to toxins. Examination and blood or urine tests may check for problems outside the brain. MRI and specialist assessment are sometimes appropriate, particularly with an unusual age of onset or other neurological signs. An ongoing seizure may require injectable medication, hospital monitoring and occasionally anaesthesia.

Long-term treatment decisions depend on frequency, severity and recovery, rather than automatically prescribing after every isolated event.

Recovery, recurrence and prevention

Keep a seizure diary with dates, duration, videos and recovery changes. Give prescribed anti-seizure medicine consistently; do not abruptly stop or change doses. Ask for a written emergency plan and advice on missed or vomited doses. Report longer, closer-together or different episodes. Persistent abnormal behaviour, inability to stand, breathing changes or further seizures need urgent advice; do not assume every prolonged recovery is harmless.

Common questions

Should I wait five minutes before calling?

No. Use the earlier two-minute call threshold, or call immediately for repeated episodes, incomplete recovery or other danger signs.

Can a dog swallow its tongue?

Do not put hands or objects into the mouth or pull the tongue; this risks serious injury.

Does shaking always mean epilepsy?

No. Tremor, fainting and other disorders may look similar; the vet needs the history and examination.

Is confusion afterwards expected?

It can occur, but severe or persistent changes and failure to regain consciousness need urgent assessment.
