Reactivity: Selecting a training protocol to suit the underlying driver.

When a dog performs visibly big behaviors in response to a stimulus, the “reactivity” label is often applied, regardless of the underlying driver.

Any stimulus can trigger these responses, but common triggers include other dogs, people, vehicles, bicycles, skateboards, and other animals.

The behaviors frequently occur whilst on-leash but can also be exhibited at a door or window in the home, at a property fence-line, or from within a crate / enclosure / vehicle.

The behaviors may include any mix of the following:

• Lunging.
