Does anyone have a solution for stopping a dog from eating

feces? Stormy my boxer,drives me nuts. I try to keep the yard picked up, but sometimes she goes crazy. This morning she was doing it right after one of the other dogs finished her business. I didn't have my shoes on and it was freezing out. I yelled at her, but she just kept on. She is like a bratty kid who acts up when their parents can't get to them. LOL
She makes me so mad because I give the dogs a premium food and then she eats that stuff.
