In 1985, we purchased a very pretty Blenheim from Canada. She was from a mating of Can. Ch. Kilspindie Bryony of Beauchamps and Ch. Kindrum Simon of Silvercrest. Her name was Beauchamps Royal Flirtation and we called her “Flirt”. We found, years later, that Flirt was a carrier for the rare chocolate color gene that runs in the longevity bloodlines of Cavalier King Charles Spaniels. Flirt lived 15+ years and was a healthy, sweet, affectionate Cavalier. She is behind all of our dogs and was our foundation female.
Prior to 1973, “All colors were recognized”. It was only in 1973 that the Breed Standard was changed to disallow for showing the wholecolor Blacks, Black & Whites, and the Chocolates. The Chocolate gene expresses itself as Chocolate Tan or Chocolate Tri. They are registered with AKC. I have also registered Chocolates with the CKCSC, USA before AKC recognized Cavaliers in 1995. After AKC recognition of the Cavalier, I registered our dogs with AKC exclusively. [I see no reason to have two sets of papers for one dog.]
