What Do You Do When a Dog Has a Seizure? (First Aid Steps)

When a dog has a seizure, you keep your dog safe, keep your own hands out of the way, look at the clock, and call your veterinarian. Phone your vet or your nearest 24-hour emergency hospital immediately if this is your dog's first seizure, if the episode runs past about five minutes, if a second seizure follows within a day, or if your dog does not return to normal afterwards. If there is any chance your dog swallowed something toxic, a human medication, a household chemical, rodent bait, xylitol, or a toxic plant, call an animal poison control service such as the ASPCA Animal Poison Control Center or the Pet Poison Helpline at the same time.

Here is the part that is hard to accept in the moment: nothing you do during the seizure itself will stop it or shorten it. Your job is not to intervene in the brain. Your job is to stop your dog getting hurt, gather accurate information, and get professional help lined up for the minute it ends.

The first sixty seconds, step by step

1. Look at the clock. Note the exact start time, or start a stopwatch on your phone. Seizures feel ten times longer than they are. The duration is the single most useful number your vet will ask for.
2. Clear the space, not the dog. Push coffee tables, chairs, water bowls and anything hard away from your dog. Moving your dog risks a bite and can worsen injury, so change the room instead of the patient.
3. Keep your hands away from the head and mouth. Dogs cannot swallow their tongue. A seizing dog has no control over its jaw and can bite through a finger without any aggression involved.
4. Turn the volume down. Switch off the television, dim bright lights, and ask everyone to speak quietly. Reducing sensory input is one of the few things that may genuinely help.
5. Cushion the head only if you can reach it safely. Slide a folded towel or thin cushion under the head from behind, never across the muzzle, and never pin the body.
6. Move other pets and children out of the room. Other dogs sometimes react badly to a seizing housemate, and the noise raises everyone's stress.
7. Film it if you have a free hand. A short video of the body posture, the limbs, the eyes and the recovery is worth more to your vet than any description you can write afterwards.
8. Watch for overheating. Prolonged muscle activity raises body temperature. A fan or a cool damp cloth on the paws and belly is reasonable, but do not pour cold water over a seizing dog.
9. Call your veterinarian. If the seizure is still going at the five-minute mark, you are calling an emergency hospital and heading there, not waiting it out.

What never to do while your dog is seizing

• Do not put your hands, a spoon, a wallet or anything else in the mouth.
• Do not hold your dog down, wrap the legs, or try to stop the paddling. Restraint does not shorten a seizure and increases injury risk to both of you.
• Do not offer food, water, or any oral medication during the seizure or while your dog is still groggy. The swallow reflex is unreliable and liquid can go into the lungs.
• Do not give human anti-seizure drugs, sedatives, painkillers or anything from your own medicine cabinet. Some are toxic to dogs at any amount.
• Do not move your dog unless they are in real danger, for example at the top of stairs, near a pool, in a road, or beside a fire. If you must move them, drag the whole bed, rug or blanket rather than lifting the body.
• Do not shout your dog's name or slap the face to wake them up. They cannot hear you, and the noise prolongs the disorientation afterwards.
• Do not drive with a seizing dog loose on a lap. Wait for the episode to end, then transport with the dog supported on the floor or in a crate with a passenger watching.

Reading the clock: when a seizure becomes an emergency

A seizure that lasts longer than about five minutes, or a second seizure that starts before your dog has fully recovered from the first, is a medical emergency, and you should be on your way to a veterinary hospital rather than waiting to see what happens. Research suggests that prolonged and clustered seizures carry a higher risk of complications than brief isolated ones, which is exactly why timing matters more than anything else you do.

What you observe	What it generally means	What to do
One seizure under roughly two minutes, dog recovers	An isolated seizure event	Call your vet the same day, log the details
Seizure still going past five minutes	Prolonged seizure activity, treated as an emergency	Go to emergency care now, call ahead
Two or more separate seizures within 24 hours	Cluster seizures	Go to emergency care now
Back-to-back seizures with no recovery between	A true emergency	Emergency hospital immediately
The first seizure your dog has ever had	Cause unknown until investigated	Veterinary appointment today
Seizure after possible toxin or medication access	Possible poisoning	Emergency vet plus an animal poison control service
Blue or grey gums, laboured breathing, injury, or very hot body	Complications needing immediate care	Emergency hospital immediately
Seizure in a very young puppy, a pregnant dog, or a diabetic dog	Higher-risk situation	Call your vet immediately for instructions

After it stops: the postictal period

The seizure ending is not the end of the event. Most dogs enter a recovery phase, called the postictal period, that can last minutes or hours. Your dog may be blind or deaf temporarily, bump into walls, pace in circles, pant heavily, drool, appear not to recognise you, seem ravenously hungry, or sleep deeply. All of this is common and not a sign that something extra has gone wrong.

In this phase, keep the room quiet and dim. Sit nearby without crowding. Block stairs and keep your dog away from water. Do not offer food or water until your dog is clearly alert, steady on their feet and swallowing normally. Note when normal behaviour returns, because the length of this recovery is another detail your vet will want.

If your dog had urinary or faecal accidents during the seizure, clean up later. Comfort first. And please do not feel guilty for being frightened. Watching this is distressing even for people who have seen it many times.

When the situation is not straightforward

If this is the first seizure your dog has ever had

Call your veterinary practice the same day even if your dog seems completely fine. A first seizure is a symptom, not a diagnosis. Causes range from toxins and low blood sugar to liver or kidney disease, head trauma, infection, and idiopathic epilepsy, which is diagnosed only after other causes are ruled out. Expect a physical and neurological exam and bloodwork, with imaging considered depending on age and findings.

If your dog is already diagnosed with epilepsy

Follow the written emergency plan your veterinarian gave you for your dog, and keep giving prescribed medication exactly as directed. Never stop or adjust an anti-seizure prescription on your own, because abrupt withdrawal can itself trigger seizures. Keep a seizure diary with the date, start and stop time, what the seizure looked like, how long recovery took, and anything unusual beforehand. Seizure patterns and treatment responses are individual, and results vary from dog to dog, so your diary is what lets your vet adjust the plan intelligently.

If it happens at night, or you are alone

The steps do not change. Clear the space, start the timer, keep your hands clear, and stay low and quiet. Have your regular clinic's number and your nearest 24-hour emergency hospital saved in your phone now, before you need them, and know the route. If you live alone, call someone to meet you at the hospital rather than driving while shaken.

If you think your dog had a seizure but you did not see it

Write down the evidence: drool on the floor, urine or stool where it should not be, a rucked-up rug, a dazed or circling dog, or unexplained disorientation when you walked in. Note the time you found them. Then book an appointment and describe exactly what you saw and what you are unsure about. Guessing is fine as long as you label it as a guess.

What your veterinarian will want from you

Bring the facts, not an interpretation. Useful details include how long the seizure lasted, whether your dog was conscious or responsive, which parts of the body were involved, whether there was paddling, stiffening, chomping, urination or defecation, how long recovery took, and whether anything similar has happened before. Add a full list of medications, supplements and recent diet changes, plus anything your dog could possibly have accessed: bins, garage chemicals, sugar-free gum, mushrooms in the garden, a dropped pill.

Video beats memory every time. If you captured even ten seconds, show it. It helps your vet distinguish a generalised seizure from a focal seizure, a fainting episode, a vestibular event or a tremor syndrome, and those distinctions change the workup entirely. Talk to your vet about whether an at-home emergency plan is appropriate for your dog, because for some dogs with a known seizure disorder, a vet may prescribe something specific to use at home under instruction.

Key Takeaways

• Time the seizure from the first twitch. Duration is the number that decides what happens next.
• Clear hazards away from your dog instead of moving or restraining your dog.
• Never put anything in the mouth. Dogs cannot swallow their tongue.
• Lower light, noise and activity, and keep other pets and children out of the room.
• Treat anything past five minutes, or a second seizure in 24 hours, as an emergency and head to a veterinary hospital.
• Expect a confused, blind, hungry or exhausted dog afterwards. That recovery phase is normal.
• A first seizure always warrants a same-day call, even if your dog seems perfectly fine.
• Keep a written seizure diary and film episodes when you can.

Seizures are a neurological symptom, and the diagnosis and the treatment plan belong to your veterinarian. Only an exam, bloodwork and, where needed, imaging can tell you whether you are looking at epilepsy, a metabolic problem, a toxin or something structural, and only a prescribing vet can decide whether medication is appropriate and when. Your role is the part no one else can do: keep your dog safe during the episode, record what happened accurately, and get that information in front of the person qualified to act on it.
