When working to modify aggressive behavior, the approach must
focus on changing a dog's emotional state first, through
carefully planned low intensity exposure to the triggering
event - while at the same time, pairing the experience with
highly pleasant things for the dog. Through this approach,
the dog's existing negative emotional association is modified
first, and as a result, the behavior changes too.
These modification techniques are known as desensitization and
counter classical conditioning. Click here to see video
examples of the process in action!
