A Retrospective Study of Canine Idiopathic Epilepsy in Referral Centers in Japan

Idiopathic epilepsy (IE) is one of the most common neurologic disorder in dogs. The aim of this study was to describe the clinical data of dogs with IE in Japan and to search for predisposing factors of IE for further investigation. Medical records and clinical information of dogs diagnosed with IE at 2 referral centers between April 2013 and March 2016 were retrospectively reviewed. It was conducted according to the consensus statement published by International Veterinary Epilepsy Task Force. A total of 70 dogs were used with a median (range) weight of 5.15 (1.85–79.85) kg and age at initial epileptic seizure onset of 4.2 (0.3–11.8) years. Fortyfour dogs were male, and 26 were female. Toy Poodles were over-represented in the present study indicating that this breed may be predisposed to IE and would be a candidate for gene study to elucidate the cause of IE in dogs
