Would anyone have suggestions on how to train a "cover your eyes/be shy" trick that doesn't involve tape on the nose? Some time ago, I taught my dog to balance a cookie on his nose and it seems that he has generalized that to the tape on his nose where he would just sit there and look at me patiently with the tape on his nose waiting for his treat. Adorable, but not quite what I was hoping for. I was wondering if you guys would have any thoughts on alternative approaches to train this trick? Thanks!
