I am trying to make a change in Merlin's dog food to the Chicken Soup for the Dog lovers soul. The problem is that he eats only that food now but suffers from Diarrhea. He is able to pick out that food from the mixed dry of ProPlan and CSFTDLS. I have taken him out at leat 10 time today where he expelled very soft stools. Has anyone else had this problem and if so how long did it last? Should I change back to proplan only?

PS We are fostering Merlin's sister. She is headed to West Palm Florida tomorrow to live with my Brother in Laws family. She will have a great home down there. Hildee is on the right. We will miss her.
