Inspired of Dr. Helmut Raiser Edgar trained the dogs in the defence work.
With training to a competition Armin saw there dogs, which worked with pressure and sensationally and stood at it very well in the obedience.
Edgar did not know "Rambo" yet, but he was immediately inspired by him. He taught Armin a lot of things not only in practice, also in nightlong theoretical explanations at a chalk board.
And it works. After approximately 8 weeks Armin had learned much, as helper and also as handler. In this time he didn't make only once defence service in his club.
The reward was a examination with 292 Pts.
Then there were following 3 years with competitions, qualifications for the German Championship (dHV DM), and so on.
In 1989 they reached with "Rambo" the 8. place on this championship.
All that Armin had to thank Edgar Scherkl.
