Why don't some trainers like head collars?
I have used head collars on my last three dogs and they've worked great. I've been taking my youngest dog to training classes and one trainer literally said to me, "I just hate that thing on her head" and another trainer said, "we don't use those here." The trainer who told me she hated haltee/holt/gentle leaders promotes pinch collars instead. I will be starting a new class with a trainer who does like head collars. Why do some trainers not like head collars?
