Can anyone help me here with any suggestions. I currently feed my 4 mnth Boxer that is 35lbs 3 cups a day of Acana - Large Puppy Breed formula. WE just switched him from Orijen - large breed puppy and he had really soft stool all the time with it so the pet store recommended us trying a lower protein diet. After reading other posts, does anybody recommend I should maybe try cutting back the amount he's being fed a day or what?? It is getting frustrating not always being able to pick up all his stool especially when we take him to the dog park. At a last note, He was just at the vet for his last set of Puppy shots and said he's healthy puppy. Please help me out if you can... Thanks
