Any good articles on seizures, or information about possible causes and actual epilepsy in the Labrador Retriever?

Thanks any help would be useful...

And remember, some Tick diseases can give a dog affects that can look like seizures. So hope its neither, but check out everything.

particularly erlichiosis in it's more advanced stages. If a dog comes back negative for Lyme, test for erlichia.
