I just switched my adult male from Innova to Wellness when I got the puppy. So, far so good, and it's supposedly a "better" food just like Innova. His stools are better than they've ever been. With the puppy, because they don't make a large breed formula, I give her half adult and half puppy formula.
You also might want to ask your vet about a dose of Albon. That can give a good jump start on getting firmer stools out of your puppy.
