Should not cause a problem really even if the dog were imported after all you can have a dog registered in this country with the same name as your dog, all the other dogs bred by the same breeder will be the same. It would be almost impossible to check that a Kennel Name (Affix) was not used anywhere else in the world, there are loads of unrecognised kennel clubs that specialise in using other peoples kennel names and there is little you can do about it.
