I have decided to use a prong collar for my almost 2 yr old male. I have used one in the past with my other GSD with no issues. The problem I am having now is my male is a long coat and the prongs seem to get jammed up in it at times. It feels like it isn't releasing as quickly as I think it should. Not sure what to do. Has anyone else had this issue? I really don't want to give up the prong collar as it is making a huge difference when we walk.
