That's the thing, Hank does well on all foods, just not long term. I would think giving him something different everyday will make things worse. I can't even give him a treat without soft stool.

The way I'm thinking is that if he is doing well on a food but after a time on it doesn't it may be that as his body "adjusts" to the food he also begins to have difficulty with it. By changing it up constantly, he wouldn't really have a chance to develop problems with the food.
