I'm not sure how the different size crates will affect the shipping cost, that might be something to check into as well. I'm sure others that might have shipped a puppy or had one shipped to them (older pup) might have an idea. I would think the smallest size that would comfortably fit the puppy. Not sure about for extended shipments, though.
