Ivar was an aggressive dog who I had for boarding training. His owners were not able to walk him because he would react to every person and dog on the street. He actually tried to attack both dogs that you see in the video, Choco and Rocky.

He is not the type of dog who is friendly to every person. I was able to get him to walk nicely around distractions, with people and dogs around. But to introduce him to people it had to be in a certain way. He does let his guard down if you introduce people properly.
