It’s not the tool…it’s the way it’s used and when. If I am being honest, I’ve seen countless owners create reactivity from harnesses… The prong collar is all about timing. Use it when your pup is already going buckwild at another dog? That’s when associations can be built between pain, reactivity, owner aggression, and overarousal. Use it before the dog loses it? That’s when you enable clear communication at the exact right time. — dog reactivity, reactive dog, dog training, dog aggression, dog behavior, Maryland
