If you look at history, this very thing IS what leads to tyrany. If people want that kind of intrusion from their government, they ought to live in a country with a history of that kind of tolerance. America is NOT the place, was never the place, was never intended by the drafters of our constitution....to be handed over to the government to run. The governement was designed to do a certain, select, minimal duties. Having the government officials regulate every aspect of our lives is NOT what America was destined to be. Sadly, because of tolerance, it is becoming an over-regulated, over-taxed country where freedoms are going down the drain fast and our freedom to pursue happiness is being stripped as the government strips our standard of living away along with our rights.
If the laws already in place and education by private citizens don't stop dogs from being sold in pet stores, then I say, "Too bad." It's a bummer, but I care more about freedom than anything because without freedom, you have nothing but an empty shell and those doggies that aren't in pet stores will lose their meaning.
