Review title: Can only shock dog if you have more than one dog?!?
Product review: I just got this and the Add-A-Collar since I have two dogs, and if I'm reading the manual right, all three buttons on the transmitter do the same thing, shock the dog. I want to be able to train them with the tone and use the shock as a last resort, so if I want to do that, I have to buy another transmitter? How stupid is that?!?
