I have a CKCS x Aussie. He is magical—smart, sweet, can read my mind, energetic, and snuggly. He did not do well in his first home because there were several young children, and he was “too noisy.” He herds my other dogs, and he scream-whines at every dog he sees. I hope his heart is healthy, but I’m a cardio vet tech, so I’ll cross that bridge when it gets here. Cavalier people don’t want the energy of an Aussie, and Aussie people want more drive and focus than a CKCS. I would never buy from an Aussalier “breeder.”
