Does anybody elses pure bread Golden Retrievers have siezures?

My 3yr old golden has been having seizures for, well since we've had him which is his whole life. he all of a sudden can't get up and starts to tighten or seize up and can't move. then he starts to drool and then after that he's all better and gets up but then he pukes up bile. i don't know really what to do w/ him. is it his breed or family genes?
