[Sadie's Mom]

I used to have Sadie on RC and she would get loose (and then very bloody) stools. I have nothing against the food, it just didn't sit well with her. Her fecals always came back normal. It kept happening, though, so I took her to an internal medicine specialist & she put us on a prescription food.

I'm not saying it's the same thing, but maybe your vet could recommend a different food to you (maybe a prescription one)
