My Kuv, Beauty is a barker, she has gotten better as she gets older, but still does alot of unneccessary barking at times when watching is more in order. We worked with her alot on her barking incessantly. She alerts us to problems, or what she feels is an uncomfortable situation, but after we are aware she continues to alert instead of "waiting" for our lead. I don't use bark collars, and tried a shack collar at one pint not for the barking (she was a car chaser) however the breed, and I assume the Pyr's are the same as they are descendants of the Kuv's, have incredibly HIGH pain tolerances, a jolt that should lay a dog down did not phase her, therefore I found it a totally waste of time, and I hated that it did inflict pain/discomfort even if she did not respond as desired. I use positive reinforcement training with her, lots of praise and a treat for obeying. But as another member stated they are guard breeds and thisi s what they do. However they should know when to bark and when to be "quiet" Beauty is much better and does not often bark out of control anymore. I don't think there is any "one" way to redirect your companion, I believe you have to find what works for your boy's personality type. Just like kids, what works to teach one won't always work for the other! Good Luck!
