I too fed my puppies ( shih tzus ) Innova Puppy from the moment I brought them home. Make sure you introduce the food over a period of 7-10 days. 1st day, 90% old, 10% new, 2nd day 80% old, 20% new...until last day 100% new food. As for treats, I gave them ( still do ) a puppy kong stuffed with kibble and sealed with a bit of Jif peanut butter.
Best wishes,
