 give it a hand signal, whatever you want it to be. I mean, if you talk to dog trainers, it's like bringing your left arm to your chest, to where your heart is. I don't know why that is the signal for come, or you can create a signal for sit or whatever you think, because that way you will still be able to communicate with your dog if the hearing does begin to continue to go. One more thing, I just talked about this.
