    What do I need to do?

    When our stocks of the old formula are depleted, you will be sent the new formula in your Auto Delivery. As the feeding guidelines for these products have changed, you may need to adjust your Auto Delivery frequency. Click here to view your Auto Delivery and manage it directly online through the Auto Delivery section in your account.

    Ensure a gradual transition

    Because the ingredients of these products have changed slightly, to avoid any dietary upsets, we recommend that you gradually transition your dog from the old to new formula over a period of 7 to 10 days.

    To make this transition possible, we recommend keeping approximately a week's worth of the old formula in reserve, so it may be necessary to bring your next scheduled Auto Delivery forward by a week.

    For detailed instructions on how to transition your pet's food, please see How to Introduce a New Food to Your Pet.
