Right now we are feeding Nutri Source For Puppies, I suggest for you to buy some IAMS For Puppies. IAMS is very close to the same formula and is much easier for everyone to find. Buy the smallest bag you can at first because your new puppy will not eat very much. 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.  Supply the bottled water for about two straight weeks and then gradually start blending the tap water in slowly over the next two week period so the puppy can get use to the chemicals. 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 IAMS For Puppies. When all the mixed food is gone than you can start feeding your new food straight. If you do not transition your new puppy over by following the instructions about the puppy could get a loose stool and get dehydrated. 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 or weeks does not help in getting your new puppy potty trained.
