Is Your Dog Having a Seizure | Canmore Veterinarian
Is Your Dog Having a Seizure?
Seeing your dog suddenly collapse, stiffen, shake, or become unresponsive can be frightening, especially when you don’t know what’s happening.
If you suspect your dog is having a seizure, focus on keeping them safe and observing the episode. What you notice during those few moments can help your veterinarian understand what happened and determine the appropriate next steps.
Recognizing the Different Signs of a Dog Seizure
A dog seizure isn’t always the full-body shaking many people picture. Depending on the type and severity, the signs can look quite different.
You may notice:
- Stiffening of the body
- Sudden collapse or loss of awareness
- Jerking or paddling movements
- Drooling or foaming around the mouth
- Repetitive or unusual movements
- Unexpected vocalization
- Loss of bladder or bowel control
- Confusion or unusual behaviour afterward
Some seizure symptoms in dogs can be much more subtle than a full-body convulsion, which is why sudden changes in movement, awareness, or behaviour are worth paying attention to.
Keeping Your Dog Safe During a Seizure
Trying to restrain your dog won’t stop the seizure and could put both of you at risk. Instead, clear furniture, sharp objects, or other hazards from the immediate area. If they’re near stairs or an edge, block access if you can do so safely.
Keep the surroundings quiet and reduce unnecessary light and stimulation.
Never put your hands or an object inside your dog’s mouth. Involuntary jaw movements during a seizure can result in an accidental bite.
Start a timer as soon as possible. Knowing how long the episode lasts is important information for your veterinarian. If it’s safe, you can also record a short video.
The Recovery Period After a Dog Seizure
The shaking may have stopped, but your dog may not immediately be back to normal.
During the recovery period, they may appear confused, restless, exhausted, unsteady, or temporarily unfamiliar with their surroundings. Give them a quiet place to recover and prevent access to stairs or other areas where poor coordination could cause an injury.
Stay nearby and watch for gradual improvement in their awareness and behaviour.
Small Details That Can Help Your Veterinarian
Because the seizure may be over by the time your dog is examined, what you observed can provide important context.
Make a note of:
- What your dog was doing before the episode
- How it started and what movements you saw
- How long it lasted
- What your dog was like afterward
- Whether this has happened before
- Any medications they currently take
- Any possible exposure to toxins or unusual substances
Bring along any video you were able to safely record. These details can help your veterinarian build a clearer picture of the episode.
Looking Beyond the Seizure to Find the Cause
A seizure results from a sudden disturbance in the brain’s normal electrical activity. The seizure itself is a symptom rather than a diagnosis, which means the next step is understanding what may have triggered it.
Possible causes of seizures in dogs can include epilepsy, metabolic problems, toxin exposure, or conditions affecting the brain, such as inflammation, injury, or structural abnormalities.
Determining the cause isn’t always possible from the seizure alone. Your dog’s age, medical history, examination, and the circumstances surrounding the episode can help guide what your veterinarian investigates next.
Signs a Dog Seizure Needs Immediate Veterinary Care
Not every seizure presents the same level of urgency, but some situations require immediate veterinary attention.
Seek emergency veterinary care if your dog’s seizure is prolonged, if several seizures happen close together, if your dog isn’t recovering appropriately between episodes, or if poisoning, trauma, or another medical emergency may be involved.
A first-time seizure also warrants contacting your veterinarian, even if your dog appears to recover afterward.
If you’re uncertain about what you’re seeing or how your dog is recovering, contact a veterinary professional for guidance.
Getting Answers After Your Dog’s Seizure
Once your dog is stable, attention turns to finding out what may have caused the episode.
Your veterinarian may review your dog’s medical history, perform a physical examination, and determine whether additional testing is appropriate based on their symptoms and individual circumstances. The information you’ve gathered before, during, and after the seizure can help guide this process.
Identifying an underlying problem, when possible, can help determine what care or monitoring your dog may need moving forward.
