Service animals are well-attuned to recognize PTSD episodes through individual scent training and monitor for hypervigilance to prevent panicking in public. In addition, service animals are trained to provide Deep Pressure Therapy (DPT) to provide a calming influence, grounding the Veteran and bringing them back from a PTSD episode. They’re a calming presence in the often-chaotic minds of Veterans, and scientific studies have shown them to have a tremendous positive impact on their lives, even reducing the need for prescription medications.
