As the title, but how can I change his ways? It can be almost impossible to put his lead on, he barks excessively, jumps around and dives around the place. As I go to grab his collar, he makes it very difficult to access it. I would prefer to see him calm when I get the lead out. I had hoped that he would get out of this by now, being almost two years old. He has always done this... Any advice please?
