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.
Laura Gumble (and the Leos in PA)
feed twice a day about two cups per meal and use a Large Breed Formula
with
a marginally lower percentage of fat than adult formulas.
Some people have found Innova to be too
rich so you may have to find another brand,
