CHARACTERISTICS AND CARE 
Cavaliers are happy active toy dogs who love to please people. They should - be quite fearless, affectionate and sporting in character and make excellent companions to young and old alike. They are easily trained. Their coat requires only occasional brushing - just enough to keep the feathering, particularly the ear fringes, from getting dirty or knotted.
HISTORY
Although the breed’s origins in Britain were similar to that of the King Charles Spaniel and date back to the Tudor and Stuart times from the 16th century. Their popularity was really established in the mid 17th century by Charles II who was rarely seen without a number at his heels. At much the same time, the breed was also popular with the aristocracy in Holland and Spain where many art masters included them in their paintings. During the early 19th century, the English breeders selectively bred for shorter muzzles and ultimately achieved this until in profile their faces were quite flat.
In 1926 an American, disturbed by the loss of the original type, offered prize money at the following five annual Crufts Shows in London, for the best specimen of the earlier type with a longer muzzle. The result was that the Cavalier breed as we know it today, was resuscitated with the added prefix of Cavalier to the title King Charles Spaniel.
