I used the shock collar just for one session. Shocked my dog 4 times. When he received a shock he stopped and looked confused. I think the shock collar is similar to electrical shock therapy. It may destroy brain tissue.Before I used it on my dog I touched the terminals with the fingers of one hand and pressed the shock button. It was painful and my forearm still feels a little strange, even days later.We wanted the collar to stop our dog from running away. We will try using a long cord to catch him when he takes off and then will yell at him when we pull him in. Hope that works better.Amazon.com is nice anyway, they took the shock collar back.
