The Science Behind Companion Dogs and PTSD: How Canines Improve Mental Health


The unconditional love and support provided by companion dogs have long been known to have a positive impact on the mental health of their owners. In recent years, awareness surrounding the use of companion dogs to help individuals struggling with Post-Traumatic Stress Disorder (PTSD) has grown. But what exactly lies behind this seemingly powerful connection between canines and mental health? In this blog post, we will delve into the science behind the role of companion dogs in alleviating PTSD symptoms and promoting emotional wellbeing.

The Hormonal Connection

When we interact with dogs, our brains release a hormone called oxytocin, often referred to as the “love hormone” or “bonding hormone.” Oxytocin is known to have a range of physiological effects, including reducing stress, promoting feelings of wellbeing, and enhancing social bonding. In individuals with PTSD, increased oxytocin levels may help combat the anxiety, depression, and social isolation that often accompany the disorder.

Canine Communication & Empathy

Dogs have an innate ability to communicate and express empathy, which can be especially beneficial for those struggling with PTSD. They easily sense their owner’s emotions and can quickly react, offering comfort, and reassurance during moments of distress. A companion dog’s non-judgmental support and consistent presence can help promote trust and feelings of safety in individuals with PTSD.

Routine & Responsibility

Caring for a companion dog also provides individuals with PTSD the opportunity to establish and maintain a structured daily routine. This routine can help improve sleep patterns and instill a sense of responsibility, reducing symptoms of depression and anxiety. Furthermore, companion dogs often need regular exercise, promoting physical fitness and overall health for both the dog and their owner.

The Benefit of Touch

For individuals with PTSD, touch can often feel overwhelming or even threatening. However, the gentle presence of a companion dog can provide them with opportunities to engage in positive, safe physical touch. The act of petting or stroking a dog has been shown to lower stress levels, heart rate, and blood pressure.

Companion Dog-Specific Training

Companion dogs specifically trained for working with individuals with PTSD are not only adept at providing emotional support but can also learn various tasks to assist their owner during challenging moments. These tasks can include recognizing triggers or early signs of distress, providing deep pressure therapy during panic attacks, or guiding their owner away from a triggering environment.


Companion dogs’ unique combination of unconditional love, empathy, and specialized training makes them powerful tools in alleviating the symptoms of PTSD and improving mental health. By focusing on understanding and supporting the science behind this amazing bond between humans and canines, we can continue to promote the role of companion dogs in mental health care and make a positive difference in the lives of those struggling with PTSD.
