Is it epilepsy or poisoning?

Question: 

My 2 year old female Labrador Retriever is suffering from severe seizers. She is currently at a local Veterinary Clinic and keeps having continuous seizers. I'm not sure if it is a form of epilepsy seizers or she possibly may have been poisoned.

Answer: 

Seizures may occur for many reasons and it will be near impossible for us to thoroughly answer your question in this forum. In a young dog though, we often worry about toxins/poisons, infections, trauma, and idiopathic epilepsy, although other causes are certainly possible. After basic bloodwork and urinalysis is completed to rule out metabolic causes for the seizures, additional diagnostic testing may include an MRI of the brain and cerebrospinal fluid analysis. Treatment for seizures can vary depending on the underlying cause. Idiopathic epilepsy is commonly treated with anticonvulsant medications, such as phenobarbital and potassium bromide. You will need to work closely with your primary care vet, or consider asking for a referral to a veterinary neurologist or internal medicine specialist who will be able to facilitate some of the advanced testing and treatments.
