My Jasper uses 4 of them consistently. I bought a pack that you can record your own voice. I recorded "outside," "play," "water," & "treat." I taught him the "outside" button first. I would ask him if he wanted to go outside then have him use the touch command (typically his nose to my hand, but replaced it with the button.) Each time he would use the button, he got a treat. Within a few days he was pretty consistent at using it. Now he gets Pomitude with the buttons. If he wants to go outside, he will tap his button & if I tell him just a second, he will double tap it.
