is there any killer app that can really stop this habit?

When i found my dog has this problem, i thought that there was a problem with my dry food, and i gave her more meats which disastrously made her poop a fine dining. Then i gave more food to her because i thought that she was too hungry. It didn't work.

It's interesting that dogs seem not to eat ALL their poop. I gave them almost the same food every day, and they leave some of it, eat a little of them.

Are there any explanation on this?

(I've eliminate all poops at home and hope this can help avoid building up this habit. Would it work?)
