Let’s be clear…an e-collar does NOT fix reactivity nor does it necessarily make a dog reactive ❌ It’s simply a communication tool and shouldn’t be used before a dog understands engagement, markers, leash pressure, and basic obedience cues. The collar keeps communication clear & works best once the relationship is already established. It doesn’t solve anything just by having it. In fact, used incorrectly, it can make things worse. — dog reactivity, reactive dog, dog training, dog aggression, dog behavior, Maryland
