Along with other breeds the vizsla may be affected by Epilepsy. The 2021 UK Kennel Club Breed Health and Conservation Plan confirms the vizsla’s predisposition, on the basis of US and Australian studies. The purpose of this page is to provide information and advice on breeding
Epilepsy
WHAT IS EPILEPSY
Epilepsy is a chronic condition that causes repeated seizures. Your vet may suspect that your dog has epilepsy if they have at least two unprovoked seizures more than 24 hours apart
WHAT CAUSES EPILEPSY
A number of different underlying diseases and other factors can cause seizures leading to epilepsy. Generally, epilepsy can be classified as “structural” (where an underlying cause can be found in the brain) or “idiopathic” (where no underlying cause can be identified, and a genetic predisposition can be presumed)
INFORMATION
The Kennel Club provides very comprehensive information and advice in an article written by leading specialists at the Royal veterinary College (RVC) – read it here
Clare Rusbridge of Fitzpatrick Referrals provides more excellent information (download) on the diagnosis and management of epilepsy
GENETIC RESEARCH
In May 2024 the Kennel Club Genetics Centre at Cambridge University confirmed a restart of their Idiopathic Epilepsy (IE) Research previously carried out at the Animal Health Trust. They also announced a broadening of the project to include Beagles, English Springers, Giant Schnauzers, Hungarian Vizslas and Irish Setters. Epilepsy is common in these breeds. Samples were sought from confirmed IE affected dogs, and healthy controls over the age of 8.
Cambridge Epilepsy Project
At the latter end of 2025 whole genome sequences for the five participating breeds were analysed and this investigation identified 800 DNA variants for further assessment. This database is expected back in early 2026 and it is planned to write up the findings soon thereafter. Click on the flyers for further detail
BREEDING
Familial patterns in the incidence and distribution of Epilepsy are apparent.There is not a genetic screening test for Epilepsy but breeders (stud dog owners too!) should make it a priority to actively monitor the condition in their dogs’ offspring and adapt their breeding programmes accordingly. It is also VITAL that owners of affected dogs should inform their breeders of the incidence of epilepsy (and other health issues too)
