This in from Reinhard. I translate only for him.
The structure has two components
- the attitude towards the helper
- technical behavior
Shade's dog has enuogh attidude towards the helper, because he is works in french ring, too.
If you look at the work at/in the blind, you can see that the dog will bites the helper not only in the arm. He will have the helper and not the arm.
It will be very difficult to condition the dog to heuwinkl or glöcknermethode.
If I understood correctly, the dog is "still" ok, but you fear that this could not remain so.
I think that here the dog training concept for the known, which was successful, not just on such an experiment should be put at risk. I would work on a visual line, which must not exceed the dog, been working as heuwinkl or glöckner.
so you could throw out the deal of the arm and leave the dog in his already successful. large construction often do you get if you want to make a "small".
so I must detlef in the above-quoted text simply agree.
that would be so my thoughts on this.
greetings from Germany
