There are changes within a dog's brain when they experience trauma. From an evolutionary perspective, its about survival. The dog's brain becomes "primed" to search out the threat in order to avoid it. "Where's the threat? Where's the threat?"
This can spread to different, yet similar triggers. For example: A dog who has gone into the yard for a potty break is startled by fireworks. The initial trigger/threat is fireworks, yet over time the dog may become more and more noise sensitive in general.
Trauma may occur as a single event learning experience -- one experience being enough to change the dog's brain. In other instances, trauma may occur through repeated exposure over time.
It's important to remember that the dog is who determines what is traumatic, not us humans. We may feel the dog should "just get over it", yet to the dog the threat is very real.
For instance, one dog may experience trauma after being barked at by another dog with no physical contact. Another dog may be attacked and injured, yet never display signs of trauma after the event. (BTW, both examples are real-life ones experienced by people we personally know.)
If your dog is showing signs of trauma, seek the assistance of a qualified professional. It goes without saying that anyone who treats trauma with aversives or corrections of any kind should be avoided at all costs.
