  5. DOG TRAINING SIMULATOR INITIAL SITUATION - no past no conditioning

    - rewarding, neutral and punishing consequences - visible reactions to consequences
  6. DOG TRAINING SIMULATOR My training will be successful when... -

    I say "Touch" - and hold two fingers so my dog can access them, - my dog comes immediately and - with a joyful body language to me and - presses its nose at the two fingers shortly.
