For months now we've been on this road. Max has stomach issues, where his starts with a rambling tummy and them mucus on his soft stool, also blood. Blood work came back fine, no intestinal parasites, the only thing I can think of is food allergies.When the colon is irritated, it secretes mucus to protects it walls, and thats what you see when they poop.Since they strain to poop that may explain the blood. You could start writing down when she has these episodes and what she ate the day or two before. Im doing this and so far chicken is the the only thing I see every time he has issues.
