Hello all, Please allow me to offer a different perspective. First of all, I do not breed, train or work dogs, nor have I done it in the past. I am certainly no expert in dog or animal behavior, and my formal education in dogs and animals, other than humans, is nonexistent. That said, I do take my responsibility as a dog owner seriously. As my 115 lb sarplaninac (the master observer) is watching everything, I am watching him and I have learned a lot about him just by watching him. He was a cute, adorable, fluffy, happy-go-lucky puppy, until one day he decided he had a serious guarding job to do. His hardwiring just kicked in. No training, no decoys, no commands needed. I almost feel sorry for the lousy bastard that decides to break into my house and gets personally acquainted with my dog's teeth. Almost. Anyway, my point is that he instinctively knows what his job is and how to do it. It is truly amazing. This is just my personal experience, nothing else, no hype. Cheers, Sue
