title: Status epilepticus and epileptic seizures in dogs.
abstract: BACKGROUND
  A special form of epileptic seizures (ES) is the life-threatening condition of status epilepticus (SE), which requires immediate and specific treatment based on a correct diagnosis of the underlying disease condition.
  
  
  OBJECTIVE
  The objectives of this retrospective study were to determine prevalence of ES and SE in dogs presenting at a veterinary teaching hospital, to identify the etiology and relative risk (RR) for SE in general and at the onset of seizures. Furthermore the outcome for dogs suffering from SE was to be evaluated.
  
  
  METHODS
  Three hundred and ninety-four dogs that were admitted to a veterinary teaching hospital (January 1, 2002 to March 31, 2008) with ES.
  
  
  METHODS
  All medical records of dogs with ES were identified by screening the clinical documentation system and evaluated for inclusion in this retrospective study.
  
  
  RESULTS
  Dogs with reactive seizures caused by poisoning had a significantly higher risk of developing SE (P < .001; RR = 2.74), particularly as 1st manifestation of a seizure disorder (P = .001; RR = 1.97). After SE, dogs with symptomatic epilepsy had a significantly lower probability of survival than dogs with idiopathic epilepsy (P < .001) and reactive ESs (P= .005).
  
  
  CONCLUSIONS
  In dogs showing SE as the 1st manifestation of a seizure disorder, intoxication should always be considered and appropriate investigations undertaken. Dogs with SE owing to toxicosis have more favorable outcomes than dogs with symptomatic epilepsy (P < .001).
