You can HELP to minize seizures by avoiding feeding him treats with dyes in them.
For some reason, food dye seems to be one of the triggers of epileptic
seizures. Even in epileptic humans, one of the main things they can do to try to minimize seizure activity is to avoid dyed foods (colored cereals) and drink only clear sodas like 7-Up or Sprite, avoiding colas and other dark or brightly colored sodas.
