I do actually live in reality as well.
I have dealt with dogs as pets and as predators my entire life. Tasting blood does not magically change a dog's brain chemistry. They might kill something and think - that was fun- and want to do it again, but it has nothing whatsoever to do with "tasting blood". People raw feed dogs all the time without them somehow turning into serial killers. Also dogs can be trained not to harm things, even when they have done so before.
Raw feed does not equate to a dog's predator instincts, so please, don't equate the two as being the same thing. The raw feed is prepped so that it is no longer 'prey' to a dog, so they don't associate the food with the actual animal, as well as the actions of obtaining that food, associated with hunting that animal, the hormones that surge through a dog's body when they are on the prowl, attack, and killing. Not all dogs experience this, just like not all humans do, but there are psychopathic humans that get a thrill out of killing another human, or animal that cannot defend itself against them. The same goes for the canine world.
It is VERY hard to retrain a dog, once it happens. Just like it is impossible to do for a human psychopath... which is why we put them in prison for the remainder of their lives, to protect society. Some are put to death, which is why we have capital punishment.
I have trained personal protection dogs, so I know, they can be trained appropriately. I have also trained search and rescue dogs. All of them were Rottweilers. My last one was actually a livestock guardian dog. He wouldn't attack my flock, or the birds, individually, but if one got out and I couldn't capture it to return the bird to its sanctuary, where it was safe, he would help me flush the bird out so I could capture it. He never harmed the bird. But you have to know the dog's personality, on an individual basis. Individual dogs can be threats.
I have a friend who just had to put his 5-month-old pup that he was training to be an LGD down because he went rogue on him. The older LGD he had is the one that attacked the pup, because the pup was attacking, and trying to kill, the goat on the property. The older LGD was responding to her training to protect the livestock, and she perceived the pup while attacking the goat and the sounds that the goat was making, as a threat and responded appropriately. My friend said that when he had to put his pup down, himself, on his property, he no longer saw 'Bandit', but a feral dog, in the dog's eyes. This same friend also shot and killed his neighbor's dog, after multiple warnings to the owner, and multiple attacks on his alpacas, on his property. The dog wouldn't stop. The dog was paired up with a Great Pyrenees, but the Great Pyrenees wasn't shot and killed, because they had it on video... the Great Pyrenees was reacting to the predator dog's actions and joining in, but once the predator dog was out of the picture, the Great Pyrenees was no longer a threat to the livestock. The pack mentality was gone. The owner of the dog was upset but realized that it was the only outcome plausible, as they couldn't control the dog's actions.
