I think you would be better to contact individual breeders whose dogs and pedigrees you like and then ask them whether they would be willing to export semen to you. If you are thinking about a UK dog, very few breeders have their dogs' semen already stored but may be willing to export on request, although it is an expensive process. If you are in Germany, it might be easier (with more chance of success) to travel with your bitch to another European dog (unless you are thinking about dogs further away in the US etc)
