Honestly. Everyone thinks of his dog, he was intelligent. We thought it well from our Labrador bitch. After the first filling of Wobblers, we had to show her good 15min long, as it could work. She had actually afraid of the device. We decided then, just so to let alone. After a few minutes, "cry" in addition to the lure, we suddenly heard sounds: you have it figured and is now running like a madwoman so around the living room. Great!!!
