Sorry to have kept everyone hanging. We just got back from MIL and I had taken Kasie with us so the vet could check her out. We were told to take her off Purina and put her on either Nutro Maxx or Science Diet. Diagnosis for her bloody stool. She was straining to poop. The vet was asking me what kind of jelly the blood looked like apparently a brightly colored blood is nothing to be overly concerned. When its darkly colored is when it is majorly concerned.
