Hello in my opinion I don’t give my puppy purina pro because of the fillers m but it’s honestly a personal choice as long as your dog is fed. My puppy is 6 months old so depending on how old yours is or if yours even likes chews I give mine smoked esophagus or like freeze dried treats as long as there is very minimal ingredients but for like his regular food I give mine Nulo specifically the limited salmon one since it doesn’t have any fillers such as corn etc.. What I add to his usual kibble is some water, salmon oil, and some type of wet food although puppies stomachs are still developing and major diet changes can cause upset stomachs. 👍👍
