On a side-note, I JUST bought some more dog food today from Petsmart. For a 44lb bag of Nutro ADULT Lamb Meal & Rice (I'm getting my pups off the puppy formula since there's no real difference) it only cost me $31!! A 20lb bag of Nutro PUPPY cost me $23. So for less than $10 more a bag (and going from puppy to adult) I got more than TWICE the amount of food!

I also forgot to add, its better to buy the new food NOW and then mix the new food with the old for a few weeks to get their body adjusted to the new formula.
