If you are using a high quality brand then it is more than likely an All Life Stages food. This means you can feed it to puppies or adults. A good brand I used to use was Innova. They have a puppy formula and adult but both are ALS formulas. When compared, the puppy formula has more fat and protein.
I would just check to make sure the puppy formula you choose is approved for all life stages. It will tell you on the bag (or usually a brand's website) somewhere around the ingredient list. |
