Another Acana lover here! Bailey had soft stools on several foods before we switched to the Pacifica grain free. Our older dog has colitis so I am use to soft stools, but Bailey now has normal stools and loves the food also. He is just a puppy so I don't think he has a food allergy, I just think this food works for him; not sure if it is because it is grain free, but it works and we are sticking with it!!
