We have successfully sent blood samples to the Netherlands now, with much thanks to Mijke. The university now has our samples and we are awaiting results back soon.
So, posting from the USA is not a problem .. this test is accessible and the bill will be sent to you once the testing is complete. Because the bill is posted to the owner and not necessarily the person submitting the test, it will be no financial burden to the breeder - we have also asked overseas breeders whose puppies we plan to have to do the testing before we fetch the puppies, so that it can be posted from within Europe.
It may be a helpful thing to ask!
