Sorry your furbaby's backed up
Try a teaspoon or two of canned pumpkin. Make sure it's just plain canned pumpkin, and not the pumpkin pie filling (has too much sugar and spices and other fillers). I bought a can awhile back and froze the rest in small containers for the next time my two have poo problems. Canned pumpkin will help with constipation and/or with diarrhea, it's a natural way to get the digestive tract back to normal.
I would also push fluids-try giving her some ice cubes, and make sure she's drinking enough water. Fiber also might help-discontinue the treats she's eating now, and try small pieces of fruit like bananas, apples (no seeds!) or veggies like spinach leaves, squash, or carrot pieces.
Edit: Make sure you DON'T give her any raisins or grapes as fruit-they can be toxic to dogs.
