Reactivity is typically defined as an over reaction to people or dogs, resulting in lunging, barking, snarling, which can lead to frustration and aggressive behavior. However, if we consider all behaviors that reflect dogs over emotional threshold as reactivity, the definition of reactivity can be expanded to include excessive timidness, submissiveness, anxiety, general overexcitement, and even the over-exuberant, happy zoomies. All of these unstable behaviors should be treated the same as typical reactivity because other dogs will attempt to neutralize these seemingly non-aggressive behaviors or the dog may lash out and harm another dog or person. Therefore, it is critically important to address all behaviors above emotional threshold so that dogs can approach the world in a more balanced state to keep all dogs and people safe.
