From what i have seen on tv and heard from people... The wolves in the balkans are very different than their north american counter parts. They are not as tall, but they have much more powerful builds overall, thicker neck and shoulders, broader more powerful jaws, and they are NOT afraid of man... It is quite cool to see though, that dogs bred as Livestock Guardians, their size, builds and attitudes go hand in hand with the predators they will encounter. Look at the co, the bears and wolves are bigger, and have harsher environment than in the balkans... making a bigger, more ""on"" dog. Mike
