Very interesting. About 1 month ago I was asked to help someone re-home their PBGV. I contacted the US and got a hold of a chair person that has someone here in Canada and one in Vermont. They worked extremly fast and was able to find a home. They are very strict with this breed and tracked the breeder who in turn agreed to have them re-home on his/her behalf. Apparently this breed, though rare and very particular have leaked out in the 'puppy mill' stream. There is one dog that was sold and then purchased by a 'bad breeder' in Minnisota if memory serves me correctly.
I do know that they have one best in show about 2 years ago, so I am certain that they will be popping up in the system very shortly. This breed certainly is not for everyone. Hide your rabbits!
