The American Kennel Club is opposed to the ongoing crisis in Ukraine. In solidarity with Ukrainian people, effective immediately, judges from the Russian Federation will not be approved to judge at AKC sanctioned events. Additionally, new requests for imported dog registrations (AKC Foreign Registration) from the Russian Kennel Federation will be denied effective immediately.
