I met a woman in Petco the other day who happened to mention that she was buying bitter apple spray to spray in her newly adopted dog's face when he pulled on the leash and/or showed any agression towards men. Of course I told her that the product was only to be used as a deterrent for chewing, and that the store sold gentle leaders or haltis that would prevent her pooch from pulling. I also told her that he was probably leary of men because he had probably been abused by one in the past, and that it might take some time for him to regain their trust. Wouldn't you know, I later saw this woman buy the bitter spray anyway. Some people should not be pet owners ~ Cathy
