When you set up your account you tell us all about your dog and we come up with a feeding plan. We can pretty much anticipate when your dog needs more food and we’ll text and e-mail you when it’s almost time to ship. You can always adjust if you need it sooner or later by going to our website on your computer or phone. We’re always learning based on those adjustments and within a couple shipments we should know exactly when you need more food. Smart!
