Scent Article Configuration - 12 articles

This configuration has been used to help the dog not only learn round the clock but also how to work an entire pile of articles.
Dylan, who is now 9 months old, was introduced to this a few days ago and did positions 1-4 correctly, followed by positions 5-8 another day. Today he will do positions 9-12 for the first time in this video.
I heavily scent the articles. I suspect that for position 11 he was not as confident since it was perhaps not as heavily scented. You will see he checks all the articles several times before settling on the correct one.
