traditional training

Tank is dog-reactive.  He and I recently started going to classes at a local training club.  Their methods focus on traditional training.  I haven't found an instructor...yet...that is very knowledgeable of clicker training.  Since I know Tank is reactive and huge, I use a Gentle Leader.  This is against policy at this club.  (A picture of a choke "show" collar is in the logo.)  It has been my intention to go to classes to have somewhere to train and a plan to focus on.  I didn't realize they would not let me use my own methods.
