In order to successfully train Dobermanns for the long distance attack, or Courage Test, we have to change their thinking. Anyone who has ever owned or trained a Dobermann knows very well that they are a thinking breed. Lower threshold dogs get aggressive easily with very little stimulation. So, we can begin right away to channel their drives into prey. Because the Dobermann responds so well to agitation, it's important not to over stress them with civil agitation.
Continuous defense leads to avoidance.
The helper must become the dog's friend. Just like a sparring partner in Boxing, the dog must trust the helper. On leash, the Dobermann bites impressively because his handler is beside him and he feels secure. The further the dog gets from his handler, the more unsure he becomes. This is typical off all lower threshold type dogs.
