I met someone recently who told me a story that floored me. She approached me while I was walking my three dogs and asked if I was a trainer. She had heard that I was and had a question for me.
She had a beautiful King Charles Cavalier puppy that was as sweet as could be. He acted like a normal 6-month old and approached my dogs with interest and a normal amount of hesitation when approaching my two big Collies and my Sheltie.
