I've been using Shock/Vibrate remote-control collars on my dogs. Bought them years ago, really, to ensure the dogs' safety. Once i taught them the voice commands they should listen for - the commands which mean a vibration is imminent i can use only my voice and rarely have to vibrate. I've shocked them a few times - once, for example, Meatball was running full sprint (well, a sprint from HER perspective) towards a horse. Not going to let that happen - meatball disregarded my verbal command so I gave her a 1 second shock. She hit the brakes hard and came back.
Their safety is worth the risk of people looking at me as a bad pet-dad. Their safety is of paramount importance.
“… the greatest detractor from high performance is fear: fear that you are not prepared, fear that you are in over your head, fear that you are not worthy, and ultimately, fear of failure. If you can eliminate that fear—not through arrogance or just wishing difficulties away, but through hard work and preparation—you will put yourself in an incredibly powerful position to take on the challenges you face" - Pete Carroll.
