Lucydogs,
Why don't you ask whoever is buying the puppy in America what food they feed their dogs - assuming they have other dogs? Or if they have had dogs in the past, what food they would recommend? If it's a packaged food they may be able to ship some over here so a couple of weeks before the puppy is due to be transported you can gradually put it on its new menu. Or, try to match the ingredient list in the U.S. food with one available here.
On Eukanuba - I have never heard a good thing about it, but it has been around for many years so I assume lots of people use it and are happy with it. It is available in the U.S. - but you cannot assume it is exactly the same food. Unless the Eukanuba we can buy here is imported from the U.S. the ingredients sold in the U.S. may be slightly different and will be sourced from different suppliers.
