Barn Hunt is a thing too. I hardly know anything about it aside from the name, but you might want to look into it.

Dogs are a lot like people. Some are genetically defective and are going to be annoying shitheads no matter what. Some are raised poorly or have bad experiences and go nuts from that. The rest are variously trainable as determined by their intelligence and biddability (innate desire to please you).
It's easier to get a dog that is naturally good and not even worry about training. I got a mutt for free. She's dumb as hell and a bitch to train because of that, but it hardly matters because the only annoying thing she really does is counter surf. I've watched friends' dogs, most of which are untrained BYB science experiments, and some of them are well behaved anyway. They're out there and they aren't that hard to find.
