Yes! Working a new dog makes you appreciate those with experience!
Question: I realize I did not specify Lesson 2 to be an ON-LEASH exercise, but have you considered working this on leash? Especially at his young age, if you limit how far he gets to go into the search area, it should encourage him to go directly to the hide and eliminate the ranging out. We want him to ASSUME there is something close by, not that he will find a hide by searching the entire area.
