Do not buy.
DO NOT BUY THIS! I bought this for a small dog as this claims to be good for dogs of 5 to 150 lbs. The instructions state there is no sensitivity setting, but I did see a slider on it and set to lowest setting. My dog was wining and crying in pain. He was rolling on the ground crying. His whines would spark more shocks, and he would cry more. There are no instructions included with this to explain how to set any sensitivity settings. My dog is so afraid of this device that I picket it off the table and he ran away to another room in the house. While I believe a similar device would work well..It needs to have settings and instructions for those settings in order to work. Also a 5 lb dog cannot take the punnishment of a 150 lb dog.
