Thanks, Performance Kennels!
I generally do trust my instincts and, this time, they were giving me red flags. I did find a reference to this breeder on another forum who has done the same thing with another buyer who bought two dogs from him and then he disappeared without handing over the registration papers to the new owners. It's interesting to me, in this age of technology, that there is no reference whatsoever to this person in any kind of search related to anything this guy ever told us about himself. None.
