The Havanese, a bichon-type dog, is the national dog of Cuba, developed from the now extinct Blanquito de la Habana ("little white dog of Havana"). The Blanquito descended... from the also now-extinct Bichón Tenerife. It is believed that the Blanquito was eventually cross-bred with other bichon types, including the poodle, to create what is now known as the Havanese. They are sometimes referred to as "Havana Silk Dogs", but this is a separate breed, which has been bred to meet the original Cuban standards.
