It’s not a bad thing to have the dog work out the problem but you have to decide if it’s demotivating to the dog if you keep turning them away from a previous hide. I RARELY suggest removing a hide but sometimes the backlash isn’t worth the effort. OR – resetting the search with different odors might be what the dog needs at this stage of the game. Hard to know and you just have to go with your gut sometimes for the benefit of the dog and the learning they’re having.
