I've been mixing the INNOVA DRY PUPPY FOOD with SugarDaddy's SCIENCE DIET for a few days now. He really seems to like the INNOVA. The pieces are a little larger with the INNOVA, but they have a little hole in the center (kinda like cat food) to make it easier to chew up.
Question, isn't loose stools a sign of upset stomach???

What does it mean if his stools have gotten harder???

Should I speed up the process of switching him over???
