The Havanese, a breed of Bichon type, 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 Bichon Tenerife, which was introduced to the Canary Islands by the Cubans. 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. Sometimes referred to as "Havana Silk Dogs," this was originally another name for the Blanquito de la Habana. The Havanese is small in size and sturdy in structure with a tail carried over its back and ears that drop and fold. The coat is abundant, long, and silky and comes in all colors. The Havanese has a spirited personality and a curious disposition, and is notable for its springy gait, a characteristic that distinguishes the breed from all others. The Havanese is considered an ideal family pet and a true companion dog. They are highly adaptable to almost any environment, and their only desire is to be with their human companions. Because of their strong social needs, Havanese will not thrive in an environment where they are isolated for several hours each day.The Havanese, while a toy dog, is sturdy and does not appear fragile or overly delicate. Weight can vary greatly, but most are from 10 to 16 pounds (4.5 to 7.3 kg). Height is 8.5 to 11.5 inches (22 to 29 cm), with the ideal being 9 to 10.5 inches (23 to 27 cm), at the withers. The body, measured from point of shoulder to point of buttocks, is slightly longer than the height at the withers, giving the dog the appearance of being slightly longer than tall. The length of the body results from the long ribcage, not the loins.
