The Maltese is a breed of dog in the toy group. It is thought to have originated in south-central Europe from dogs of spitz type. Despite the name, it has no verified historic or scientific connection to the island of Malta. Adult Maltese range from roughly 1.4 to 4.5 kg (3 to 10 lb). The international FCI standard specifies a weight of 3–4 kg (6.6–8.8 lb); the American Kennel Club calls for a somewhat lighter weight of 4–7 lb (1.8–3.2 kg), with 4–6 lb (1.8–2.7 kg) preferred, They are usually 18 to 30 cm (7 to 12 in) tall. The Maltese is kept as for companionship, for ornament or for showing. It is ranked 59th of 79 breeds assessed for intelligence by Stanley Coren. The Historie of the World. Book III.
