Are you talking about teh VanDen Heuvel K9 here on the CT/NY border? If so yes they are neighbors of one of my friends. The produce beautiful dogs. We contemplated one of their puppies about 2 years ago but opted to wait out for just the right puppy and found one with another breeder (temperment/gender/coat color) that we wanted.
Lexi- GSD/Bull Mastiff
Calvin- poyldactyl cat
