Reactivity rarely starts with barking or lunging. Most dogs show subtle signs of stress long before a visible reaction happens. This guide helps you recognize early changes in posture, movement, focus, and breathing — so you can step in sooner, reduce pressure, and prevent escalation before your dog feels overwhelmed.

Reactivity isn’t disobedience — it’s emotion. Learn what happens inside your dog’s body and brain when fear, arousal, and stress take over, why “he knows sit” doesn’t matter when he’s scared, and how understanding canine reactivity helps you build safety, confidence, and calm communication on every walk.

Learn how to read your dog’s body language and understand what yawns, tail wags, ear positions, and eye expressions really mean. This guide unpacks canine communication so you can build trust, prevent misunderstandings, and deepen your connection with your dog. Discover why listening to your dog’s body is the key to a happier, safer relationship.
