I am sure it is hurtful that Van and many others knock the lack of health testing and, well I'm not in the know enough, whatever else, but surely we can't be blaming a puppy buyer backing out because of online harassment? If that we're the case that puppy buyer probably isn't what you want anyways, if they felt, in their hearts, this was the perfect dog and breed for them they wouldn't let someone online sway them.
It would make no sense for me to knock health testings because no one in the breed does it yet.
I've gotten some serious hatemail for the breeder I chose for my next dog and it just didn't change my opinion. I say, consider the source.
