How do you stop dogs from eating their poop?

I have two little digs and they will not stop eating their poop. Does any one have any suggestions on how to get them from stop eating their poop?!?!?

clean it up right after they go.

Clean up after them! Try putting a bit of pineapple on their food. If that doesn't work, the vet can give you a powder to sprinkle on their food called For-Bid.

Change their diet. Their bodies can sense that they are not recieving enough nutrients in their diet so they are trying to compensate that by eating their poop. Put them on a higher quality food.And pick up the poop as soon as they do it. Don't give them the opportunity to eat it.
