I wish I were closer, I'd come with you! I HATE these puppy stores!!!
I would be willing to bet that they will tell you they get their puppies from local breeders and never get them from puppy mills or farms. That's what they ALL say!!! I have inquired into MANY of them, and that seems to be their classic answer around here.
I am so glad to hear you are trying to get something done. I have been trying to do the same here, but I've found that Ohio has horrible humane laws.

So, I'm thinking I have to start there and try to get some of these laws changed.
GOOD LUCK!!!
