Cavachon Puppy DARLING Blenheim Boy Ah, the classic blonde & white version of the Cavachon, in my opinion, the closest in appearance to the Cavalier King Charles Spaniel, I love these little Blenheims, they are so sweet and loving, always smart and trainable and they seem to have an extra measure of the Cavalier sweetness of temperament. Alfie is especially blessed with beauty and the most delightful personality, he’s so affectionate and while he loves to play, he’s always ready to snuggle in your lap for a nice nap and a tummy rub. He’s a smallish puppy guy, I’m thinking about 10 to 12 pounds when he’s all grown up!
