We will now move on to a larger novel area to search. This assignment is ONLY if you are ready. Please make sure that your dog is confident in smaller areas before trying anything larger.
Essentially, keep the challenge the same but just allow the area to be larger.
If you are ready to up the Ante. Pick a larger quiet/easy novel location with little to no obvious distractions. An easy location is one without people nearby, or near critter areas, and on a non-grass surface. Make sure the area has “structure” to catch/hold odor.
Remember that if the hides are taking longer than about 1:30 to find, you have probably overwhelmed your dog.
