A short while back I posted a thread about having problems with a clients neighbors pit. This morning I pulled up and the dog burned the 100 yards between the two houses and would not let me out of the truck or even open the door. My client who saw me out the window called her neighbor and asked her to come get the beast which she did quickly and took him back home and put him in the house. My client then comes out and hands me this item called a Dazer 11 and told me "I bought this just for you and that da*m beast to try and keep peace in the neighborhood before that dog attacks you or someone else working at my place. He explained it was suppose to send out a signal that dogs can't stand. He then pointed it at his dog, a friendly lab and two cats and pushed the button. You would have thought someone lit a fire under those animals azzes the way they scattered! I did not see the pit bull anymore just heard him barking non stop on the neighbors porch. I wanted to try it on the pit but was glad I did not have to encounter him. It would be nice if the dazer worked. That way I am safe and the dog is not injured in anyway. Just wondered if anyone on here had ever used them?
