Reactivity

Reactivity describes an intense response to a trigger. A reactive dog may bark, lunge, pull, freeze, spin, or struggle to disengage when a person, dog, sound, vehicle, or environment becomes too much.

Common Signs

  • Barking
  • Lunging
  • Pulling
  • Fixating
  • Stiff Body
  • Freezing
  • Unable to Disengage
  • Slow Recovery

Important Distinction

Reactivity is a description of behavior, not a diagnosis. A reactive dog is not automatically aggressive, and two dogs showing similar outward behavior may be reacting for very different reasons.

What Can Help

Useful work begins with distance, management, recognizing threshold, improving handler timing, and creating controlled opportunities for the dog to notice a trigger without being overwhelmed.

When To Get Professional Help

Professional help makes sense when reactions are escalating, recovery is slow, walks feel unsafe, the dog has made contact, or the owner cannot create enough distance to train safely.
