Dash (1830–1840) was a King Charles Spaniel owned by Queen Victoria. Victoria's biographer Elizabeth Longford, called him "the Queen's closest childhood companion", and in the words of the Oxford Dictionary of National Biography, he "was the first in a long line of beloved little dogs".

The King Charles Spaniel is a small dog breed of the spaniel type. In 1903, the Kennel Club combined four separate toy spaniel breeds under this single title. The other varieties merged into this breed were the Blenheim, Ruby and Prince Charles Spaniels, each of which contributed one of the four colours available in the breed.
