You know where my mind goes to when I think of this? shock therapy... I know, it might make someone twist their head sideways... but hear me out...
There are people who are afraid of dogs, and the cure is to put them in a room full of harmless puppies... they scream, freak out.. and then realize everything is fine...
Something like that.... i gotta mature the idea..
I had a friend who had a rescue dog who was afraid of cardboard boxes, and the trainer's prescribed treatment was for her to train him to do 100 behaviors involving a cardboard box.
We are on to something... im telling you...
