We currently are feeding your puppy “Kirkland Signature Super Premium Chicken, Rice and Vegetable Formula,” which we purchase from Costco. If you prefer to feed your puppy a different brand of food, start by adding a small amount of your puppy’s new food with their current food, gradually increasing the new food amount and decreasing their current food amount at each feeding. Continue this method for approximately one week. To make this process easier for you, we will be sending a sample of the food we are feeding your puppy home with you. If you do decide to switch your puppy’s brand of food, I recommend that the first ingredient be a meat and no corn products.
