Overview

Epilepsy is a genetic condition in Schipperke, Beagle, and Finnish Spitz dogs due to a mutation in the CFA37 gene. Dogs with the condition experience random, recurring seizures. Epilepsy can be 5 to 10 times more common in some dog breeds than it is in humans.

Symptoms

Symptoms of epilepsy may appear at any time. Depending on the type of seizure, they may include sudden stiffening of the limbs and collapse, repetitive “paddling” movements, uncontrollable chewing or drooling, shaking, and more. Seizures can last anywhere from a few seconds to a few minutes. Dogs return to normal brain activity within a few minutes.

Care and Management

There is no known cure for epilepsy. Anti-epileptic medications can help control both the frequency and severity of seizures.

What are the signs of epilepsy in dogs?

Symptoms of epilepsy may appear at any time. Depending on the type of seizure, they may include sudden stiffening of the limbs and collapse, repetitive “paddling” movements, uncontrollable chewing or drooling, shaking, and more. Seizures can last anywhere from a few seconds to a few minutes. The CFA37 gene mutation responsible for this condition can be identified with a DNA test. Schedule a vet visit to get a clear picture. Our vets are also available for a consult if you want guidance before the appointment.

What should I do if my dog has been diagnosed with epilepsy?

There is no known cure for epilepsy. Anti-epileptic medications can help control both the frequency and severity of seizures. Consistency with medications is key. Set reminders and never adjust doses without talking to your vet first. Reach out to our vets for a consult — we can help you prioritize what matters most and plan for follow-up appointments.

Is epilepsy in dogs treatable?

A cure isn't available for epilepsy, but effective management exists and many dogs live comfortably with the right approach. There is no known cure for epilepsy. Anti-epileptic medications can help control both the frequency and severity of seizures. Stay consistent with the management plan and keep up with regular vet checks. Early intervention on any flare-ups or changes makes a big difference in long-term outcomes.

How much should I budget for my dog's epilepsy?

A DNA test for the CFA37 gene costs $75–$150. Combined with a veterinary exam and any additional workup, initial diagnostics typically run $300–$800 total. Anticonvulsant medications typically run $30–$100/month, with blood monitoring every few months at $80–$150. Ongoing neurological monitoring typically costs $150–$300 per visit every 3–6 months. Physical therapy or hydrotherapy, if recommended, runs $50–$100 per session. If you have pet insurance taken out before diagnosis, check your coverage for genetic conditions — it can make a real difference.

Which dog breeds are at risk for epilepsy and can it be prevented?

Epilepsy has been identified in breeds including Schipperkes, Beagles, and Finnish Spitzs. The condition is complex, likely involving multiple genes including CFA37. DNA testing for the CFA37 gene is available and gives a definitive answer. No single DNA test can predict this condition. Prevention relies on tracking affected lineages and careful breeding decisions. Responsible breeders test both parents before any mating. Not sure how to interpret your breeder's health testing? Our vets can break it down for you in a quick consult.
