BTW, I used to show German Wirehaired Pointers and train them for field work. I bred three small litters over the years. Kept a male and female from my last litter born in 1989. The male died in February 2004 and his sister died in April of last year. (As I sit here typing this, their photos surround me.) So I understand the issues as they pertain to breeders of all types.
GWP! I used to have (and will again) Spinone, which used to always be accused of being BAD GWP! :)
Anyway, check out this link, it may shed some light for you:

The biggest problem with legislation in these areas is the law of unintended consequences. I too would love to shut down puppy mills and pet shops that sell puppies (except for those who adopt out pets from the local shelter). However, it's tough to draft a law that shuts them down, but doesn't harm the small hobby breeder.
I have to run, show this weekend, but nice chatting.
