"We have a boxer/lab mix that is 10 months old. He comes to work with us, we own a car repair shop. Our dog has ran across the road, which is very busy, and has tried to chase/race people as they pull into our lot. Keeping him in the tiny office doesn't allow him to get a lot of excercise, or be social, so this collar allowed him many freedoms!
He learned his boundaries in ONE DAY! No more flags, he just hears the beep and stops, turns around and starts trouble somewhere else!!
We love it and are purchasing another collar to go with it for our employee to bring his dog to work too!"
