Surely this cannot be the case everywhere in the US, no? I mean in rural areas people still have their dogs breed, I assume?
It’s not illegal to breed dogs anywhere in the US AFAIK. The act of leaving your dog un-neutered/spayed is looked down upon and suggested against because they can breed on their own (and produce a lot more dogs) if they escape their owners. Lots of people breed dogs inside and outside metropolitan areas.
