Symptom: Fits & Seizures – When Should I Contact a Vet?

What are the signs of fitting or seizures in pets?

A fit or seizure occurs when there is abnormal electrical activity in the brain. It can look frightening to witness, and although many pets recover well afterwards, any seizure should be taken seriously and discussed with your vet. 

Common signs include: 

  • Becoming restless or staring into space before the seizure starts  

  • Falling over, becoming stiff, then jerking or paddling their legs  

  • Losing consciousness  

  • Passing urine or faeces during the seizure  

  • Afterwards, your pet may appear confused, restless, unsteady or temporarily unable to see. This recovery period can last from a few minutes to several hours before they gradually return to normal.

Frequently asked questions

Why is my pet having fits?

- Idiopathic Epilepsy: The most common cause of recurrent seizures in otherwise healthy dogs. "Idiopathic" simply means that no underlying cause has been identified.   
- Toxins: Certain poisons, medications and toxic substances can trigger seizures. 
- Brain disease: Brain inflammation, tumours or head injuries can all cause seizures.
- Underlying medical conditions: Liver disease, kidney disease, low blood sugar and other illnesses can affect the brain and lead to seizures. Related reading - Kidney disease in cats 
- Congenital or inherited conditions: Some pets are born with conditions that increase their risk of developing seizures 

DOs - My pet is fitting/seizing, what to do at home

- Keep your pet away from hazards. Move furniture or other objects if necessary to help prevent injury, but don't put yourself at risk.  
- Time the seizure and, if safe to do so, record it on your phone. This information can be very helpful for your vet. 
- Reduce noise and other stimulation. Dim the lights, turn off the television and keep the area as calm as possible.  
- Contact your vet once your pet has recovered, especially if this is their first seizure or they are not already being treated for epilepsy. 

DON’Ts - My pet is fitting/seizing, what not to do at home

- Don't try to restrain your pet. Allow the seizure to run its course while keeping them safe from injury.  
- Don't put your hands or anything else near your pet's mouth. They will not swallow their tongue and may bite unintentionally.  
- Don't offer food, water or medication until your pet is fully awake and able to swallow normally.  
- Don't leave your pet unattended until they have fully recovered, as they may be confused or unsteady. 

My pet is having a fit. When is it an emergency?

Seek immediate veterinary attention if your pet: 
- Has a seizure lasting more than five minutes.  
- Has more than one seizure in 24 hours (cluster seizures).  
- Has a first-ever seizure.  
- Does not recover normally after the seizure or remains unconscious.  
- Has a seizure after a head injury or possible toxin exposure.  

If your pet has been prescribed emergency seizure medication by your vet, give it exactly as directed while arranging immediate veterinary care.
