Cavaliers come in four color variations: Black & Tan, Ruby, Tri-Color, and Blenheim.
President Ronald Reagan, as a Christmas gift to his wife, Nancy, adopted a Cavalier King Charles Spaniel, Rex, while in office in 1985. Rex's responsibilities included helping to light the National Christmas Tree and he was widely known for refusing to enter the Lincoln Bedroom.
On the popular TV series, Sex and the City, Charlotte York adopted a blenheim Cavalier and named her Elizabeth Taylor Goldenblatt.
Dash was Queen Victoria’s beloved Tricolor Cavalier. His tombstone is inscribed with the following message written by the Queen herself:
"Here lies Dash, the favorite spaniel of Her Majesty Queen Victoria, by whose command this memorial was erected. He died on the 20th December 1840 in his ninth year. His attachment was without selfishness, his playfulness without malice, his fidelity without deceit.
Reader, if you would live beloved and die regretted, profit by the example of Dash.”
"You can’t help being enchanted by the big, twinkling eyes of the Cavalier, a gentle, pint-sized bundle (13 to 18 pounds) of tail-wagging joy. Friendly and easily trained, the Cavalier is an ideal companion for families with young children and other pets. "Sex and the City" fans will recognize this breed as the same as Charlotte’s dog, Elizabeth Taylor, but they first gained popularity as the preferred pet of King Charles II and still appear frequently on the UK Kennel Club’s list of most popular breeds."
