Right now we are feeding Nutri Source For Puppies, the link provided will take you to a website with the same food we feed. We have found that our puppies do very well on it and I say when you find something that works stick with it. We also recommend these other puppy foods Eukanuba, IAMS or Science Diet. What ever you do, don't go cheap on dog food because they will eat the same amount of your moneys worth, they just shoot it out the back end. Notice: We have Well water so I recommend you use bottled water for about the first month to make the transition easier on the puppy, the chemicals in city water can cause a loose stool so please take note when transitioning your new puppy. We will be sending a small bag of puppy food that your puppy has been eating, feed it to your new puppy for the first three days, then mix it half and half with the food your choice to feed. When all the mixed food is gone than you can start feeding your new food straight. This will help the transition of changing puppy foods. We will be sending your new puppy in an Airline approved Pet Carrier for the ride on the plane unless of coarse you are picking it up from the house. You can use the Pet Carrier to Crate Train your new puppy, start as soon as you receive him/her. Waiting for a couple of days only prolongs the problem. We recommend going to the Purina site for crate training tips, it is loaded with great information on raising your new puppy as well, here is the link: www.purina.com Here is a link to our Frequently asked questions. FAQs Potty training is the Sixth question on the page.
