I think that as long as you run them through the dishwasher on a regular basis, and keep them clean, it probably won't make a bit of difference whether you use metal, plastic or ceramic. Generally, plastic can harbor bacteria in the little slits created by utensils, stirring, etc. If your dog loves to tote them around and chew on them, then plastic might not be the way to go.
Or, if you want to approach it from another angle, don't feed them in anything you wouldn't want to eat out of.
