If your dog has a seizure, stay calm and focus on safety. Move nearby objects away, keep your hands away from the mouth, and time the episode if you can.
After it ends, keep your dog quiet and warm, then contact your veterinarian for advice. A first seizure, repeated seizures, or any seizure that lasts more than a few minutes needs urgent veterinary attention.
What To Do When A Dog Has A Seizure?
Protect your dog from injury, do not restrain them, and do not put anything in their mouth. Time the seizure, note what happened before and after, and contact a veterinarian as soon as possible. Call emergency care right away if the seizure lasts longer than a few minutes, repeats, or your dog does not recover normally.
What to do during the seizure
Most seizures are frightening to watch, but your main job is to keep your dog safe until the episode passes. Dogs usually cannot swallow their tongues, so trying to open the mouth is dangerous for both of you.
- Stay calm and speak softly.
- Move furniture, sharp objects, stairs, or other hazards away if you can do so safely.
- Dim lights and reduce loud noise if possible.
- Time the seizure with a clock or phone.
- Keep children and other pets away from the area.
- Do not hold your dog down or try to stop the movements.
- Do not put fingers, spoons, or any object in the mouth.
If your dog is near water, stairs, a road, or a hot surface, carefully move them only if you can do it without getting hurt. Otherwise, keep the area clear and wait for the seizure to end.
What to do right after the seizure
Many dogs are confused, restless, blind-looking, or temporarily unsteady after a seizure. This post-seizure phase can last minutes to hours, depending on the dog and the cause.
- Let your dog recover in a quiet, safe space.
- Offer water only when they are fully alert enough to swallow normally.
- Keep other pets and children away until your dog is steady and calm.
- Watch for stumbling, pacing, unusual hunger, temporary blindness, or disorientation.
- Contact your veterinarian and report what happened, especially if this is the first seizure.
Do not offer food immediately if your dog seems dazed or has trouble standing. A dog that is still confused may choke or fall.
When a seizure is an emergency
Some seizures need immediate veterinary care. Do not wait to “see if it happens again” when any of these red flags are present.
- The seizure lasts more than 5 minutes.
- Your dog has more than one seizure in a short period.
- Your dog does not wake up, recover, or breathe normally afterward.
- Your dog has trouble walking for a long time, collapses, or seems severely weak.
- Your dog has a high body temperature, severe agitation, or appears to be overheating.
- You suspect poisoning, toxin exposure, head trauma, or a medication reaction.
- Your dog is very young, elderly, or has a known medical condition and the seizure is unusual for them.
If the seizure is still happening when you arrive at the clinic, call ahead so the team can prepare. If your dog has repeated seizures or a seizure cluster, emergency treatment may be needed quickly.
What may cause a dog seizure?
Seizures can have many causes, and you cannot tell the cause from the episode alone. A veterinarian may consider epilepsy, toxin exposure, metabolic disease, infection, liver problems, kidney disease, head injury, or other neurologic issues.
Common triggers and risk factors
- Eating something toxic, such as certain human medications, illicit drugs, or poisonous plants
- Low blood sugar, especially in small puppies or dogs with certain illnesses
- Heatstroke or severe overheating
- Head trauma
- Underlying liver, kidney, or endocrine disease
- Idiopathic epilepsy, where no other cause is found
Some breeds are more commonly diagnosed with epilepsy than others, but breed is not a diagnosis. Any dog, mixed-breed or purebred, can have a seizure.
What information to record for your vet
Details from you are often very helpful. If you can safely do so, write down what you saw or record a video after the seizure starts, without putting yourself or your dog at risk.
- How long the seizure lasted
- What your dog was doing before it started
- Whether the dog collapsed, paddled, drooled, urinated, or defecated
- How many seizures happened and how close together they were
- How your dog acted afterward
- Any possible toxin exposure, missed medications, recent illness, or injury
Bring a list of all medications and supplements your dog takes, including flea, tick, and heartworm preventives. Even products that are normally safe can matter if a dose was missed, doubled, or combined with something else.
Should you take your dog to the vet after one seizure?
Yes, in most cases you should call your veterinarian after a first seizure, even if your dog seems normal afterward. A single seizure may not be an emergency if it was brief and your dog recovered fully, but it still deserves medical review.
Seek prompt veterinary advice if:
- This is your dog’s first seizure
- Your dog has any chronic illness
- Your dog is taking medication that could lower seizure threshold or interact with other drugs
- The seizure happened after possible toxin exposure
- Your dog is older and this is a new symptom
Your veterinarian may recommend an exam, bloodwork, and sometimes additional testing to look for an underlying cause. The exact workup depends on your dog’s age, history, and what happened during the episode.
Common mistakes to avoid
Well-meaning owners sometimes make the situation more dangerous. Avoid these common errors when a dog has a seizure.
- Do not put your hands near the mouth.
- Do not try to pull out the tongue.
- Do not give food, water, or pills during the seizure.
- Do not shout, shake, or restrain your dog.
- Do not assume the seizure is “just epilepsy” without a veterinary exam.
- Do not wait at home if the seizure is prolonged or repeated.
How age and health can affect seizure response
What to do when a dog has a seizure is mostly the same for every dog, but the urgency and likely cause can vary. Puppies may seize from low blood sugar, toxin exposure, or congenital problems, while older dogs may need evaluation for metabolic disease, brain disease, or other age-related conditions.
Dogs with diabetes, liver disease, kidney disease, or a history of toxin ingestion need especially prompt veterinary care. If your dog already has a seizure disorder and the pattern changes, that also warrants a call to your vet.
Living with a dog prone to seizures
If your veterinarian diagnoses epilepsy or another recurring seizure condition, you may need a long-term management plan. That plan is individualized and may include medication, follow-up exams, and trigger avoidance.
- Keep a seizure log with dates, times, and duration.
- Give prescribed medication exactly as directed by your veterinarian.
- Do not stop seizure medication suddenly unless your vet instructs you to do so.
- Reduce access to stairs, pools, and unsafe surfaces if episodes are unpredictable.
- Maintain a stable routine when possible, since stress and missed medication can complicate management.
Training can also help with safety. A reliable recall, crate comfort, and calm handling make it easier to protect your dog during recovery and transport.
When to contact a veterinarian even if the seizure stopped
Call your vet soon after the episode if your dog seems normal, because the timing and details still matter. You do not need to diagnose the cause yourself before seeking help.
Contact a veterinarian promptly if your dog had a seizure and also has vomiting, fever, weakness, unusual behavior, trouble breathing, or a recent history of eating something unsafe. These signs can point to a more serious problem.
Bottom line
When a dog has a seizure, keep them safe, time the episode, and avoid putting anything in their mouth. Get urgent veterinary help for prolonged, repeated, or severe seizures, and arrange follow-up care after any first-time episode.
