ALSO per moving into lesson 4 and outside- remember to keep the area you start to work in SMALL. When she bypasses the container indoors with the odor the first time (that is fine) and comes back to it, it shows a confidence dilemma. She likely smells it is there but is checking to see if there is a stronger source. When outside the potential area to check just got HUGE, and you want to keep her focused in a certain section. Might not be problematic- but keep your eye out for if she misses it and doesn’t return to it when practicing outdoors.
Give her time to figure it out herself, and be patient. You guys are doing great.
