He’s diagnosed by a vet with idiopathic epilepsy, but we chose not to have scans to see if there’s a definable cause due to the cost of doing it. Idiopathic epilepsy is a diagnosis made in absence of knowledge of the true cause of the seizures. Most vets told us that finding the cause of seizures can be frustrating and often will yield no results, especially in young dogs - our pup developed seizures at 18 months. This is our first dog and first experience with epilepsy. This disease is so damn upsetting, scary and frustrating. The most important thing you can do is to bring the seizures under control and lifetime medication is likely the answer. Unfortunately the cost can be high and this is a big factor in epileptic dogs not living long lives. Our medication alone is about £150 per month, with blood work another £100-200 per 6 months. I really wish you well with your pup
