Attempts were made to recreate the original Cavalier King Charles Spaniel as early as the turn of the 20th century, using the now extinct Toy Trawler Spaniels. These attempts were documented by Judith Blunt-Lytton, 16th Baroness Wentworth, in the book 'Toy Dogs and Their Ancestors Including the History And Management of Toy Spaniels, Pekingese, Japanese and Pomeranians' published under the name of the 'Hon. Mrs Neville Lytton' in 1911. Cavaliers are active and sporting. Cavaliers are successful in conformation shows, obedience and agility and they also make wonderful therapy dogs due to their sweet, gentle natures. The breed is adaptable in their need for exercise, happy with either sleeping on the couch or taking long walks. Cavalier King Charles Spaniel Club. Retrieved 14 November 2009.
