RE: I'm more concerned with DS drowning in the water bowl
I completely agree that scheduling food and water times is the best approach. In addition to the hazards already mentioned, dry dog food is a choking hazard!
If you have a pet that is used to grazing, don't worry, they won't starve! They will quickly figure out what they need to do to get what they want (or learn to ask for it when they want it at a different time - both of our dogs and our cat ask for the water dish a couple of times during the day, we give it to them and then pick it up when they are done).
