At home remedies for gastrointestinal upset include feeding a bland diet--boiled rice, boiled chicken or hamburger, and small amounts of cottage cheese. Also canned pumpkin (non-spiced) and wheat or whole grain bread can help by providing fiber; this bulks the diet and can help the gastrointestinal tract move things along. Plain yogurt is also good for diarrhea; it contains lactobacillus-a good probiotic promoting healthy bacterial flora.
Fiber ,they have dog foods made with fiber buy alittle bag of it mix it with her normal food, it works But first remember loose bm is the bodies way of ridding itself of something .If your dog ate something bad or has worms be wary but if you know the cause like to many table scaps I say this method really works. Fiber you want to encourage is soluble which means absorbs liquid like anything you put in water and it swells without disappearing
Well make her eat some cheese and crackers because it will bind you up and stop the diarrhea
