The Cavalier King Charles Spaniel was the favourite dog of the British Royal Family, loved by Mary Queen of Scots and King Charles I and Charles II. It is even more sought after among the British pleasure dogs and is second in popularity after the Yorkshire. The average Cavalier King Charles Spaniel can cost between $800 and $2,000 depending on its type. A slightly better looking Cavalier King Charles Spaniel can cost around $3,000. If it is a racing dog or the offspring of a racing dog, the price is usually in the tens of thousands of dollars.
