Poor Piper! It sounds like something is definitely wrong. Problems with growth, low energy levels, and diarrhea with blood can be caused by a number of different things - she may have a severe case of intestinal parasites, some type of infection, or even an internal birth defect such as a liver shunt. I would recommend taking her to the vet for an exam as soon as possible, as this sounds like it may be a serious problem. He/she can do a fecal exam to check for parasites, and may recommend blood work or other testing if needed to help make a diagnosis and see what can be done to treat the problem.
