Labs in general are notorious for having insane food drive to the point where when you run into one that does not, they're certainly an exception. All dogs in general have food drive, as it is a necessity to live, but they're given basically unlimited access to it which diminishes it's value in their psyche.

Once you pull that prey drive out of a working dog and associate it with something such as a ball, there's no greater satisfaction this planet than doing the thing for that animal. It usually works better as a reward for what we're doing, is more instant, but also it can be deadly for a dog to eat food when they're at working-level activity.
