No problem. Innova also has an adult formula that is ALS, too. The only difference and why they are labeled "puppy" and "adult" is the different amounts of protein and fat. I plan to switch mine to the adult fomula when Daisy is over a year. Since yorkies usually don't over-eat, it's OK to feed them the puppy (higher protein/fat) formula past a year.
Innova is a SUPER good food so if your little guy likes it, you're lucky. I went through a gazillion samples before I found what Nick liked. I'm just glad he picked such a healthy brand!
