I've read the threads about the poop eaters and said to myself "Thank God that's not MY dog."! I've recently switched Dixie's food from Royal Canin (which she wasn't very fond of) to Blue Buffalo (she loves) within the past week. She hasn't had any trouble with diarrhea and really likes the food. BUT...I've caught her twice trying to eat her poop!!! Why now?!! My dainty little puppy is turning gross on me! HELP!
