Stop Eating Shit Already!

What did pet owners do in the days before Amazon to get their dog to stop treating their shit as a delicacy?

Some other suggestions for the pet owner squicked out by their dog's eating habits:

1. By better food so they can tell the difference between meals and shit.
2. Pick up shit before the dog takes in in their own hands to clean up.
3. Accept fido might just be dumber than average. 50% of 'em fall in this category.
