I would stay away from any type of multivitamin for a number of reasons.
As long as the foods you're feeding are for "all life stages" or puppy foods, they will contain all the vitamins and minerals a growing puppy needs. With some multi's, you run the risk of upsetting the balance of the overall diet and you don't want to feed an unbalanced diet to a growing puppy.
At the other end of the spectrum, a lot of pet multivitamins contain really tiny amounts of vitamins and minerals. This is because these manufacturers know that any substantial amounts could actually cause harm when fed with a commercial food. Since the foods you're going to feed are already balanced, why waste your money on tiny amounts of unneeded vitamins and minerals?
