One natural remedy that really works is Doc Ackerman's Seizure Formula (Only Natural Pet has it).
According to the article in the Healthcare Library on seizures:
"A
natural hypoallergenic diet along with
fish oil,
flax seed oil, taurine, phosphatidylcholine, B complex vitamins,
trace minerals, antioxidants (VitC, Vit E, Selenium, Vits A&D) in products
such as
Canine Antioxidant Formula,
Cell Advance or
Vetri-DMG can be therapeutic for epileptics. "
I hope this is helpful!
