Dogs and Post-Traumatic Stress Disorder



Writing for Veterinary Practice News, veterinary behaviorist Dr. Nicholas Dodman, who teaches vet students about PTSD, discussed one of his cases.

Dog Shot by Police Develops PTSD

It involved a dog that decided to follow a police officer in pursuit of a suspect. The dog's interest was peaked by the excitement of the foot chase. Unfortunately, the officer shot the dog, thinking he was about to attack him.

The dog fell to the ground, bleeding from his wounds, and was close to death. His owner scooped him up and raced to a nearby animal hospital, where the veterinary staff was able to save him.

The dog slowly recovered physically from his wounds, but his behavior was forever changed. Normally a sensitive soul but relatively confident, the dog became very anxious and hyper vigilant. He never took his eyes off his owner and had to be near him every minute.

The dog also developed an extreme fear of police cars, flashing lights, and black people (the police officer who shot him was African-American). He had what appeared to be nightmares and developed nocturnal separation anxiety so pronounced the owner and his son had to take turns staying up with the dog so the other one could sleep.

Even though there was no way to determine exactly what was going on with the dog's emotional state, his behavior met the primary criteria for human PTSD, including anxiety lasting more than three months, hyper-vigilance, avoidance of stimuli associated with the trauma, difficulty sleeping, and nightmares.

Abandoned Dogs in Fukushima Show Signs of PTSD

A study published in the journal Scientific Reports documents the condition of dogs unintentionally abandoned after the March 2011 earthquake and major nuclear incident in Fukushima, Japan.



Study authors concluded that their results "... suggest the possibility that stress can induce excessive, deep psychosomatic impacts with implicit behavioral manifestations, such as deficits in attachment and learning ability also in dogs. Long-term care and concern regarding the psychological impact of disasters appears necessary in humans and companion animals."

Post Traumatic "Negative Learning"

According to Dr. Dodman, the post-traumatic learning that results from a terrifying experience depends to a certain extent on the release of catecholamines in the brain in response to the event. Catecholamines are hormones -- including dopamine, norepinephrine, and epinephrine -- produced by the adrenal glands and released into the blood during physical or emotional stress.

Some post-traumatic learning is helpful in that it allows animals to remember a dangerous circumstance so it can be avoided in the future. But this "negative learning" goes from functional to dysfunctional when it becomes excessive and debilitating.


ICU Experiences Can Trigger PTSD in Dogs

It's not only gunshots, earthquakes and war zones that can create PTSD-like responses in dogs. Dr. Dodman believes that similar to people, dogs can also be traumatized by events like automobile accidents and ICU experiences.



If you have a dog who is or might be suffering PTSD-like symptoms, I recommend you consult with both an animal behaviorist with experience in treating pets with PTSD, and a veterinarian who can suggest natural therapies to work in conjunction with behavioral therapy.
