I have two 3-yr-old chocolate labs who were gun shy and they now love the dummy launcher . I have an 8-yr old black lab who looks for what to fetch when he hears a gunshot so he loved the launcher at first shot. it took some time, but first one 3-yr-old chocolate and then the second decided they could get past the noise for the fun of fetching. they got nervous when i held it like a gun from my shoulder, so i started with shooting from the hip, and now they don't mind if I shoot from the shoulder. haven't tried a real gun yet, but this makes as much noise. the yellows will throw 300 yards pretty easy and quite loud. the greens are all i really need.
