The King Charles Cavalier are pure breeds, so both parents are King Charles Cavalier.  They can be tri-colour, blenheim or ruby in colour.

King Charles Cavaliers are very friendly dogs that are affectionate and always willing to please. The Cavalier loves to be included as one of the family. Happy to lie at home or easily pleased with a run at the park, these friendly dogs are more interested in being with their owners than anything else. They need a good-sized yard and regular walks to keep them stimulated. They live for cuddles and are sweet in nature. Typically, the Cavalier lives without fear, is gentle and above all, affectionate.  They can grow to a height of 30 to 40cm and weight up to 6 kilos.
