Recurrent seizuring is a common neurological problem in dogs and can present diagnostic difficulties for the attending clinician. Associated interictal neurological deficits strongly suggest brain disease but the frequency of structural abnormalities in patients without such deficits is unknown. In this study the prevalence of clinically significant magnetic resonance imaging (MRI) abnormalities was determined in two groups of interictally normal dogs, those younger than 6 years and those older than 6 years of age. In the former group, only 1/46 dogs (2.2%) had significant MRI abnormalities, whereas in the latter group, 8/30 (26.7%) were abnormal. None of the dogs had an identifiable metabolic cause for the seizures. These findings suggest that the diagnostic yield of advanced neuromiaging techniques in young seizuring dogs without interictal neurological deficits is low, but reaffirms their value in similar older individuals.
