Do puppy mill laws hurt responsible dog breeders?

Oregon has a new law going into effect with the goal of curbing problems with puppy mills. A few other states have similar laws or are considering them, but Oregon’s is considered quite comprehensive. It will limit breeders from owning more than 50 adult dogs for breeding, require more comprehensive record keeping, and regulate how the dogs are treated – no more small crates and no more stacking crates. Each dog has to get at least one hour a day out of the crate. Also, pet shops will be required to provide puppy buyers information on where their new pet came from.

This all sounds totally sensible and minimally humane to me. But I know the law of unintended consequences can create unforseen problems. With one exception that ended badly, I have always adopted mixed breed dogs, so I have no personal experience with large scale breeding operations, bad or good. Anyone here have experiences they’d care to share?
