Dogs that have strong instincts and/or were developed to work autonomously can just be challenging to train. My Great Pyrenees mix just turned two and I'm still working on certain things with him. The strict, dominance-asserting stance that usually works great for me, even with an Akita, just doesn't track with him. I get the best results by being gentle and encouraging and using games to make good behaviors into habits. He's quite intelligent and understands what I want quickly, but unless something is ingrained to the point of being a habit there's no guarantee he will prioritize it over what
he thinks he should be doing.
Also, his instinct to maintain a perimeter makes him easily distractible by scents. I can only imagine if he had the nose of a hound...
