With guardian breeds, I want to see that the breeder is producing dogs that are versatile, that can do what they are bred to do, and that they are true to that guarding instinct and can still be a stable companion dog you can take in public with you sometimes (not necessarily to huge crowded events, but for walks in the park and such) without worrying that they will eat someone for looking at them wrong. I want to see that the breeder knows their dogs and does things with their dogs. It can be tricky to do these things with guardian breeds if you are keeping a lot of them at once in kennels. I wouldn't say a kennel is a deal-breaker, but it is hard to gauge their stability in different situations if they don't do much beside sit in a kennel.
Besides, in the guardians they survive on closeness with their people first, food and water second. Being alone too much can literally make them crazy, worse than other dogs.
