Hahaha no kidding. I love that response
I'd be fooling you if I said this is foolproof with my dogs but I try to make life easier for them in the following way.
Their collars beep twice when I hit the tone button. If I want them to heel, and don't want to use my voice, I use a two note whistle, same note. I snap my fingers twice if that isn't appropriate, say if there are folks close around. I tap my chest twice if I want them to see an action. All of it means, to them, "Pay attention, your personal lord and savior is requiring you to heel."
Using the cadence of two makes it easier for them to understand, in my small universe of experience. No need to over complicate things.
