Hi :)
As Barbara suggested, it is worth contacting the Kennel Club. If you click
HERE it will take you to the info page on the Long Coat Chihuahua, with a list at the bottom of the contact numbers for various clubs:)
If you click
HERE, it will take you to the main Kennel club page.
Also, not sure if this is the right page, but I think this is the
Danish Kennel ClubHope that helps
Ali :)
