There is sparse published scientific data on the associations between neutering and the severity and survival of dogs with idiopathic epilepsy. This study used VetCompass™ data on 117 Labrador retrievers and 57 Border collies, diagnosed with idiopathic epilepsy, to examine the evidence base for these associations. Prior published research has suggested a beneficial effect of neutering in dogs with idiopathic epilepsy. However these results do not support a recommendation to neuter dogs with idiopathic epilepsy within an evidence-based treatment plan.

Key findings of this study include:      

• The majority of neutered epileptic dogs were neutered before the onset of seizures. 
• Age at onset did not differ between intact and dogs neutered before onset.
• Cluster seizures did not differ across sex-neuter groups.
• Intact males had longer median survival times than dogs neutered before onset.
• Intact females had longer median survival times than dogs neutered before onset  

RVC’s VetCompass™ project analyses anonymised veterinary clinical records from over 1,500 UK vet clinics to enhance understanding and improve the health and welfare of all companion animals.
