Is this statement true? Or does it just mean that you can't get a genuine, certified, Labrador Retriever from your corner pet store?
As is so often the case, the news stories barely contain any information, and are presented as "these people like it but those people don't", which is pretty useless.
I'll bet that under this law, a pet store can still work directly with a dog breeder to provide dogs to their customers. They can just sell a "dog package", which consists of everything you need for a new puppy, and work with the dog breeder to arrange delivery if you are looking for a specific breed. I suspect the only thing disallowed under this system is the display of animals from some source other than a rescue center. It's not that you can't get a purebred from a breeder. It's just that the breeder can't put a dog into a pet store on consignment.
Of course, there's not enough information in the news articles to be sure of that, but that's what it appears to me.
