  • Do time and record the event e.g. on your phone, if safe to do so, sharing this with your vet maybe helpful Do keep him/her cool to avoid overheating  

  • Do reduce stimuli (switch light off, or television) to minimise sensory input 

  • Give medications, such as use of rectal ampule during your pet fitting to stop fitting only if prescribed by your vet 

  • Do contact your vet for an appointment after your pet has come around, especially if this is the first time. 

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

  • Do not restrain your pet and allow the seizure to run its course 

  • Do not put anything in his/her mouth 

  • Do not offer food or water until your pet is fully conscious

When should I think about going to the vets?

If it's your pet's first seizure or if your pet is seizing even if already on medication for it, it's essential to seek veterinary attention to determine the cause and appropriate treatment plan.  

Even if the seizure is brief and your pet seems to recover quickly, it's important to contact your vet for a check-up. 

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

Dog seizures lasting more than five minutes require emergency care. This condition can cause brain damage or overheating. Multiple seizures within 24 hours (cluster seizures) also need quick attention, even if each seizure is brief. 

Call us right away if your dog's seizure continues beyond five minutes or if they have more than one seizure in a day.
