<P> The Second World War caused a drastic setback to the emerging breed, with the vast majority of breeding stock destroyed because of wartime hardship and food shortages . For instance, in the Ttiweh Cavalier Kennel, the population of sixty dogs dropped to three during the 1940s . Following the war, just six dogs would survive as the new beginning from which all present - day Cavaliers descend . These dogs were Ann's Son, his litter brother Wizbang Timothy, Carlo of Ttiweh, Duce of Braemore, Kobba of Kuranda and Aristide of Ttiweh . The numbers increased gradually, and in 1945 the Kennel Club first recognised the breed in its own right as the Cavalier King Charles Spaniel . </P> <P> The history of the breed in America is relatively recent . The first recorded Cavalier living in the United States was brought from the United Kingdom in 1956 by W. Lyon Brown, together with Elizabeth Spalding and other enthusiasts, she founded the Cavalier King Charles Club USA which continues to the present day . In 1994, the American Cavalier King Charles Spaniel Club was created by a group of breeders to apply for recognition by the American Kennel Club . The Cavalier would go on to be recognised by the American Kennel Club in 1995, and the ACKCSC became the parent club for Cavaliers . </P> <P> Historically the Cavalier King Charles Spaniel was a lap dog and is small for a spaniel, with fully grown adults comparable in size to adolescents of other larger spaniel breeds . Breed standards state that height of a Cavalier should be between 12 to 13 inches (30 to 33 cm) with a proportionate weight between 13 to 18 pounds (5.9 to 8.2 kg). The tail is usually not docked, and the Cavalier should have a silky coat of moderate length . Standards state that it should be free from curl, although a slight wave is allowed . Feathering can grow on their ears, feet, legs and tail in adulthood . Standards require this be kept long, with the feathering on the feet a particularly important aspect of the breed's features . </P> <P> The Cavalier King Charles Spaniel and the English Toy Spaniel can be often confused with each other . In the United Kingdom, the English Toy Spaniel is called the King Charles Spaniel while in the United States, one of the colours of the Toy Spaniel is known as King Charles . The two breeds share similar history and only diverged from each other about 100 years ago . There are several major differences between the two breeds, with the primary difference being the size . While the Cavalier weighs on average between 13 to 18 pounds (5.9 to 8.2 kg), the King Charles is smaller at 9 to 15 pounds (4.1 to 6.8 kg). In addition their facial features while similar, are different; the Cavalier's ears are set higher and its skull is flat while the King Charles's is domed . Finally the muzzle length of the Cavalier tends to be longer than that of its King Charles cousin . </P>
