 They are often sensitive to humans and have the ability to adapt their behavior accordingly by doing tasks such as preventing panic, waking a veteran from a nightmare, and nudging to help the veteran “stay in the present”.Dogs also provide veterans with a nonjudgmental and safe environment that can help a veteran express feelings and process thoughts without interruption, criticism or advice.Interactions, such as petting, playing and walking, with the dog can increase physical activity, reduce anxiety, and provide encouragement to stay in the present moment.
